The study was aimed to explore the relationship between the root distribution at different growth angles and the ratooning ability in sugarcane, and to screen the iconic root indexes of strong ratooning in sugarcane. Three sugarcane varieties with different ratooning ability, Yunzhe 08-1609 (A), Yunzhe 05-51 (B), Yuetang 93-159 (C) and strong ratooning sugarcane germplasm Erianthus arundinaceus (D) and Saccharum spontaneum (E), were used as the materials. The root morphology of plant and ratoon crops was continuously measured under the conditions of conventional planting in field. The root biomass and quantity of sugarcane varieties with strong ratoon ability increased continuously during elongation stage of plant crop, and the highest was in the angle range 0°-30° from the vertical direction, followed by that of 30°-45°. The root biomass and numbers in ratoon crop were significantly higher than those in plant crop. The root biomass and numbers in varieties A and B were the highest in the angle range 30°-45°, and that in variety C was the highest in 45°-65°. The root biomass in E. arundinaceus and S. spontaneum was much higher than that in sugarcane varieties in both plant and ratoon crops, the root number in S. spontaneum was the largest while that in E. arundinaceus was close to that in sugarcane varieties. The root biomass of the two wild germplasm materials in plant crop was the highest in the angle range of 0°-30°, while in ratoon crop, the root number distribution in E. arundinaceus was similar at three angle ranges, and of whitch in S. spontaneum was similar in the ranges of 30°-45° and 45°-65°. The root number in variety A was the highest (46.43%) in the angle range of 0°-30° at late elongation stage of plant crop, followed by the range of 30°-45° (42.74%) at late elongation stage of ratoon crop. The root number proportion of S. spontaneum and E. arundinaceus was the highest in the range of 0°-30° at elongation stage of plant crop, followed by the range 45°-65° at elongation stage of ratoon crop. The top five indicators correlated with the ratooning ability were the root surface area, root volume, root length, root fresh weight, and root number within the angle range of 0°-30° to the vertical direction. For evaluating the ratooning ability of sugarcane, it is suggested to refer to the root index in the angle range of 0°-30° from the vertical direction in plant crop, and the root fresh weight could be used as a key index for preliminary screening of the ratooning ability. In addition, if there was no rhizomes, the ratooning ability can be predicted by the ratio of average single root weight in ratoon to that in plant crop.

为探究甘蔗不同生长角度根系分布与甘蔗宿根性的关系,筛选出强宿根甘蔗根系的标志性指标。本研究以宿根性有差异的3个甘蔗品种云蔗08-1609(A)、云蔗05-51(B)、粤糖93-159(C)及强宿根性甘蔗近缘种质斑茅(D)、割手密(E)为材料,大田常规种植,连续测定一新一宿的根系形态。结果表明:强宿根性甘蔗品种新植伸长期根生物量和数量持续增加,在与竖直方向夹角0°~30°范围内最高,其次是30°~45°;宿根蔗的根生物量和数量较新植蔗明显增加,品种A和B根生物量和数量分布在30°~45°范围内最高,品种C则在45°~65°范围内最高。强宿根性近缘种斑茅、割手密根生物量不论新植还是宿根均远高于甘蔗品种,而根数量则是割手密最多,斑茅根数量与甘蔗品种接近,二者新植在0°~30°范围内根生物量最大;斑茅宿根在3个角度的根数量分布相近,割手密宿根则在30°~45°和45°~65°范围内分布相近。品种A在0°~30°范围内新植伸长后期根数量占比最高(46.43%),其次是在30°~45°范围内宿根伸长后期(42.74%)。割手密和斑茅根数量占比在0°~30°范围内新植伸长期最高,其次是45°~65°宿根伸长期。与宿根能力相关排名前5的指标分别是新植与竖直方向呈0°~30°夹角范围内的根系表面积、根系体积、根长、根鲜质量以及总根数量。在研究甘蔗宿根能力时可参考新植材料与竖直方向夹角0°~30°范围内的根系指标,该角度根鲜质量可作为初步筛选宿根性的关键指标。另外,若无横走茎则可通过宿根与新植的平均单条根鲜质量比值进行宿根性判定。

为探究甘蔗不同生长角度根系分布与甘蔗宿根性的关系,筛选出强宿根甘蔗根系的标志性指标。本研究以宿根性有差异的3个甘蔗品种云蔗08-1609(A)、云蔗05-51(B)、粤糖93-159(C)及强宿根性甘蔗近缘种质斑茅(D)、割手密(E)为材料,大田常规种植,连续测定一新一宿的根系形态。结果表明:强宿根性甘蔗品种新植伸长期根生物量和数量持续增加,在与竖直方向夹角0°~30°范围内最高,其次是30°~45°;宿根蔗的根生物量和数量较新植蔗明显增加,品种A和B根生物量和数量分布在30°~45°范围内最高,品种C则在45°~65°范围内最高。强宿根性近缘种斑茅、割手密根生物量不论新植还是宿根均远高于甘蔗品种,而根数量则是割手密最多,斑茅根数量与甘蔗品种接近,二者新植在0°~30°范围内根生物量最大;斑茅宿根在3个角度的根数量分布相近,割手密宿根则在30°~45°和45°~65°范围内分布相近。品种A在0°~30°范围内新植伸长后期根数量占比最高(46.43%),其次是在30°~45°范围内宿根伸长后期(42.74%)。割手密和斑茅根数量占比在0°~30°范围内新植伸长期最高,其次是45°~65°宿根伸长期。与宿根能力相关排名前5的指标分别是新植与竖直方向呈0°~30°夹角范围内的根系表面积、根系体积、根长、根鲜质量以及总根数量。在研究甘蔗宿根能力时可参考新植材料与竖直方向夹角0°~30°范围内的根系指标,该角度根鲜质量可作为初步筛选宿根性的关键指标。另外,若无横走茎则可通过宿根与新植的平均单条根鲜质量比值进行宿根性判定。

The study was aimed to explore the relationship between the root distribution at different growth angles and the ratooning ability in sugarcane, and to screen the iconic root indexes of strong ratooning in sugarcane. Three sugarcane varieties with different ratooning ability, Yunzhe 08-1609 (A), Yunzhe 05-51 (B), Yuetang 93-159 (C) and strong ratooning sugarcane germplasm Erianthus arundinaceus (D) and Saccharum spontaneum (E), were used as the materials. The root morphology of plant and ratoon crops was continuously measured under the conditions of conventional planting in field. The root biomass and quantity of sugarcane varieties with strong ratoon ability increased continuously during elongation stage of plant crop, and the highest was in the angle range 0°-30° from the vertical direction, followed by that of 30°-45°. The root biomass and numbers in ratoon crop were significantly higher than those in plant crop. The root biomass and numbers in varieties A and B were the highest in the angle range 30°-45°, and that in variety C was the highest in 45°-65°. The root biomass in E. arundinaceus and S. spontaneum was much higher than that in sugarcane varieties in both plant and ratoon crops, the root number in S. spontaneum was the largest while that in E. arundinaceus was close to that in sugarcane varieties. The root biomass of the two wild germplasm materials in plant crop was the highest in the angle range of 0°-30°, while in ratoon crop, the root number distribution in E. arundinaceus was similar at three angle ranges, and of whitch in S. spontaneum was similar in the ranges of 30°-45° and 45°-65°. The root number in variety A was the highest (46.43%) in the angle range of 0°-30° at late elongation stage of plant crop, followed by the range of 30°-45° (42.74%) at late elongation stage of ratoon crop. The root number proportion of S. spontaneum and E. arundinaceus was the highest in the range of 0°-30° at elongation stage of plant crop, followed by the range 45°-65° at elongation stage of ratoon crop. The top five indicators correlated with the ratooning ability were the root surface area, root volume, root length, root fresh weight, and root number within the angle range of 0°-30° to the vertical direction. For evaluating the ratooning ability of sugarcane, it is suggested to refer to the root index in the angle range of 0°-30° from the vertical direction in plant crop, and the root fresh weight could be used as a key index for preliminary screening of the ratooning ability. In addition, if there was no rhizomes, the ratooning ability can be predicted by the ratio of average single root weight in ratoon to that in plant crop.

甘蔗是我国重要的糖料作物,在我国有近90%的蔗糖产自甘蔗[1]。在甘蔗收获后,地下蔗蔸茎节上的芽萌发,再次生长发育而成的甘蔗称为宿根蔗。宿根蔗具有节省种茎材料、种植工作量和成本,及早发、早熟、糖分高等优点[2-4],在原料蔗生产中占有重要地位。在我国甘蔗宿根年限一般较短,广西、云南蔗区宿根年限一般为2~3年,宿根蔗产量降低导致的宿根面积少和年限短是导致我国甘蔗生产成本高的主要因素之一[4-6]。因此,研究宿根材料的关键性状、选育宿根性强的甘蔗品种、研发延长甘蔗宿根年限的栽培技术对我国甘蔗产业具有重要意义。
根系作为养分吸收器官[7],主要分布在0~60 cm土层[8],是水分和营养物质吸收、储存、转化的重要场所,在作物结构支撑、抗逆和产量形成等方面有着重要作用[9]。同时,甘蔗根系与其宿根能力密切相关,甘蔗大量的根系形成被认为是宿根能力好的性状之一[10],甘蔗根系在前一季地上部分收获后的1~7个月内[11]保持着一定的活性以维持蔗蔸活力并促进地下芽萌发和地上部分的再生生长,直至被新根系取代后才死亡和分解。因此,在干旱的春季,上一季所留的甘蔗根系具有吸收深层土壤水分的能力,是宿根蔗苗早发及快速生长的保障。
甘蔗根系类型分为高度分枝的浅根系、斜向下的支撑根和向下深入可穿透犁底层的深根系,甘蔗深根系最深可达到超过6 m的土壤深度[12],因此,深根系赋予了甘蔗植株对较深层土壤水分的利用能力;深根系是作物抗旱的重要特征,可以维持根系细胞水势,增强细胞对干旱的耐受性,提高作物抗旱能力[13]。前人通过对冬小麦根系氮素吸收对抗旱性的影响研究发现,深根系和作物抗旱性强弱有关[14],深根系可以增加根系对深层土壤中氮的吸收,有利于提高氮利用率[15];而浅根系可以从表层土壤中吸收水分和养分[12],增加作物对浅层土壤中磷的吸收利用[16];支撑根和深根系是支撑地上部分的重要器官,通过吸收水分和增加作物抗倒伏能力参与作物的生长发育[17-19]。相关研究表明,根系越长、数量越多,根鲜质量越大,根系对水分和养分的吸收能力越强,更有利于甘蔗增产[20-21]。ZHAO等[22]研究表明根系的根长、根表面积、根体积与宿根蔗株高、产量呈显著正相关[9]。相对于甘蔗来说,其深根系、支撑根和浅根系的生物量、数量分布以及根长、表面积等形态数据较为缺乏,另外新植和宿根的根系性状及其与宿根能力强弱的关系值得进一步研究。
通过根系测算分析不同角度的根系分布,可以估算作物根系分布模式[23]。根系生长角度决定了根系类型和根系在垂直方向上的分布,并且决定了作物水分和养分的获取特性[24],较浅的根系类型可以促进植物对表层土壤中养分的吸收利用[25]。ZHU等[25]研究表明,玉米浅根系的分布对磷的吸收利用十分重要。ARULMOZH等[26]对干旱胁迫下水稻深根系和根系生长角的研究发现,与竖直方向0°~65°夹角范围内深根系和产量显著相关。前人研究结果表明,水稻的深根特性主要取决于根系生长角度、深层土壤中根系的分布、根系穿透紧实土壤层或犁底层的能力[27]。魏淑丽[28]通过对玉米根系研究发现,田间条件下根系与水平面夹角在10°~80°范围内,耕层根系生长角度对玉米深层根数量有重要影响。增加深层土壤中根数量可以提高作物对深层土壤中水分和养分的吸收和利用[29-30]。因此,研究甘蔗不同生长角度根系形态及其与宿根性之间的关系有一定意义。
本研究以3个不同宿根性的甘蔗品种和2个强宿根近缘种为材料,通过分析其新植和宿根伸长前期、伸长中期、伸长后期的根系在不同角度范围内的生物量、数量及形态差异,以期为筛选强宿根甘蔗标志性根系指标及强宿根甘蔗品种的选育提供理论依据。
供试材料为云南蔗区推广种植面积较大且宿根性有差异的3个甘蔗品种云蔗08-1609、云蔗05-51和粤糖93-159,其中云蔗08-1609[31-32]和云蔗05-51[33-34]宿根性较强,粤糖93-159宿根性稍弱[35]。此外,选择了强宿根甘蔗野生近缘种质斑茅[36-37]和割手密[38-39]材料各1个。并初步将上述材料的宿根能力分级为:斑茅、割手密(4级)>云蔗08-1609(3级)>云蔗05-51(2级)>粤糖93-159(1级)。
本研究在云南省农业科学院甘蔗研究所第一实验基地进行,设置强宿根品种云蔗08-1609(A)和云蔗05-51(B),强宿根近缘种斑茅(D)、割手密(E)为处理,宿根性一般的粤糖93-159(C)为对照。使用随机区组试验设计,大田试验每个处理设置4个重复,小区面积为36 m2(行距1 m,行长6 m),每个小区设置2行保护行。开沟深度30 cm,沟底宽15 cm,甘蔗品种双芽种茎均匀摆放在沟底,下芽量为72芽/行,下芽后一次性施入氮磷钾含量为15∶15∶15的复合肥1200 kg/hm2+3%噻虫嗪30 kg/hm2,覆土后覆透明全膜,分蘖完成后揭膜培土。斑茅和割手密为种茎育苗移栽,移栽后不覆膜,行距1 m,株距1 m。新植成熟期收获后的第一季宿根苗期施入同样的肥料和农药后进行松蔸培土,不覆地膜。材料种植以及管理方法与常规大田甘蔗种植一致。
种植的5个处理材料在新植和宿根伸长期以丛为单位对地上部和根系进行取样。新植蔗为春植,在伸长前期(NE)即2022年8月(种植后110 d)、伸长中期(NM)10月(种植后170 d)、伸长后期(NL)12月(种植后235 d)取样,每个处理分别选取长势均匀、无病虫害的植株,挖取根系(长50 cm×宽50 cm×深60 cm),尽量保持根系的完整性,同时将对应的地上部分取回实验室待测,每个处理3次重复。新植材料于2023年4月砍收后对其进行常规宿根管理,并于2023年伸长前期(RE)7月(砍收后145 d)、伸长中期(RM)9月(砍收后200 d)及伸长后期(RL)11月(砍收后255 d)进行取样,取样方法同新植材料。
将根系连同蔗蔸清洗干净后,按照根系生长方向与竖直方向的夹角分为0°~30°、30°~45°、45°~65° 3个角度。将根系分别按上述3个角度剪下并记录各个角度根的数量,然后再次清洗晾干表面水分称取鲜质量,进而使用WinRHIZO根系分析系统对根系形态进行扫描分析,得到根长、根表面积、根体积、根尖数、分叉数、交叉数。将扫描分析后的根系放入105 ℃恒温箱烘至恒重并称重。
地上部分和根系同时取样,根系与地上部分分离后,记录每丛株数,将地上部分茎叶分离分别称重,计算鲜质量,然后分别将茎叶放入恒温箱105 ℃杀青15 min,80 ℃烘至恒重,并分别称取干质量。
使用Excel 2007软件和SPSS 19.0软件,采用单因素方差分析(S-N-K事后检验)和相关性分析(双变量相关性-皮尔逊-双尾)对甘蔗生物量及根系形态数据进行统计分析,采用GraphPad Prism 9、Excel软件制图。
3个甘蔗品种在新植和宿根的伸长前期株数均高于其他伸长时期(表1)。甘蔗完成分蘖后进入伸长期,随着生长,无效分蘖消亡,到伸长中期,植株数量趋于稳定;宿根蔗的无效分蘖减少量高于新植蔗,这种无效分蘖消亡造成的植株数量减少的现象在宿根蔗上表现得更为明显。强宿根性近缘种D、E每丛的株数均高于3个甘蔗品种,且每丛株数至少是甘蔗品种的6倍以上。另外值得注意的是斑茅、割手密从伸长前期至伸长后期,并无明显的植株数量减少的现象。
3个甘蔗品种每丛甘蔗生物量除新植伸长中期外,在其余5个生长时期强宿根性品种A、B地上部分生物量整体上高于宿根性一般的甘蔗品种C,在宿根伸长中期和伸长后期达到显著差异水平(P<0.05)。3个甘蔗品种单株生物量与一丛的生物量变化趋势相似(图1),与对照品种C相比,宿根性较强的品种A和B地上部分生物量在新植伸长前期和宿根的3个伸长期均显著高于品种C(P<0.05)。
斑茅和割手密在新植伸长前期地上部生物量显著高于甘蔗品种,而斑茅从新植的伸长前期到宿根的伸长中期,生物量均显著高于3个甘蔗品种及割手密(P<0.05);到宿根伸长后期,斑茅鲜重与甘蔗品种A和B之间无差异,其干质量除新植伸长前期外均显著高于其他材料;割手密地上部分生物量在伸长中期及伸长后期与甘蔗品种地上部分生物量趋于无差异,甚至到宿根伸长后期割手密地上部分鲜质量低于甘蔗品种A和B;斑茅和割手密单株地上部生物量在6个伸长期均显著低于甘蔗品种地上部生物量,整体上斑茅生物量高于割手密(图1)。

在与竖直方向夹角30°~45°范围内,新植伸长前期强宿根性品种A、B根鲜质量高于品种C,干质量差异不显著;从新植伸长前期到新植伸长后期,品种A、C根系生物量呈现先增加后减少,而品种B表现为先减少后增加;宿根伸长期强宿根性品种A的根系生物量平均值显著高于另外2个品种,3个甘蔗品种根系生物量较新植伸长期明显增加;宿根伸长后期,强宿根性品种A的增加量较为明显,根鲜质量是品种B宿根伸长后期的1.83倍、品种C宿根伸长后期的1.69倍,根干质量是品种B宿根伸长后期的2.34倍、品种C宿根伸长后期的1.69倍。总体看,强宿根性品种A根鲜质量表现为由宿根伸长前期至宿根伸长后期持续增加,品种B、C均表现为由宿根伸长前期至宿根伸长后期先减少后增加;强宿根性品种A根干质量变化趋势和鲜质量类似,品种B根干质量在宿根伸长前期达到最大值,随后至宿根伸长后期持续减少,宿根性一般的品种C根干质量由宿根伸长前期到后期呈现先减少后增加的趋势。

3个甘蔗品种新植伸长期平均根系生物量在与竖直方向夹角0°~30°范围内最高,其次是30°~45°。第一年宿根品种A和B的根系生物量分布在30°~45°范围内最高,而品种C的根系生物量则在45°~65°范围内最高。强宿根性近缘种斑茅、割手密的单株根系生物量低于甘蔗品种,在3个生长角度中,新植在0°~30°范围内根系生物量最大,宿根则在45°~65°范围内最大。

在与竖直方向夹角30°~45°范围内,强宿根性品种A新植和宿根3个伸长期根数量平均值均显著高于宿根性一般的品种C;由新植伸长前期至新植伸长后期,强宿根性品种A、B的根数量呈逐渐增加的趋势,宿根性一般的品种C呈先增加后减少的趋势;宿根伸长期3个甘蔗品种根数量较新植伸长期明显增加,均呈先增加后减少的趋势。宿根伸长中期,强宿根性品种A的增加量较为明显,是品种B宿根伸长中期的1.48倍、品种C宿根伸长中期的1.66倍。强宿根性近缘种斑茅、割手密在新植伸长期呈先增后减的趋势,斑茅在宿根伸长期呈先减少后增多的趋势,而割手密根数量随生长时期的变化持续增加。
在45°~65°范围内,新植伸长期品种A和B根数量平均值显著高于品种C,品种A和C的根数量呈先增后减的趋势,品种B的根数量在伸长初期最高,随后减少;宿根伸长期根数量同样高于新植伸长期,3个甘蔗品种根数量均在宿根伸长中期达到最大值。强宿根近缘种斑茅、割手密在宿根伸长期的根数量较新植有所增加,割手密根数量略高于斑茅。
在上述3个角度范围内,新植伸长期3个甘蔗品种根数量均值在与竖直方向夹角0°~30°范围内最高,其次是30°~45°;在宿根伸长期,品种A和B根数量均值在30°~45°范围内最高,在其余2个角度相当,品种C的根数量在3个角度分配相当。斑茅、割手密新植的3个伸长期根数量均值在0°~30°范围内最高,斑茅宿根3个伸长时期根数量均值在3个角度分布一致,割手密宿根3个伸长时期根数量均值在30°~45°和45°~65°范围内分布一致。

根系生物量方面,在与竖直方向夹角0°~30°范围内,新植伸长期根鲜质量平均占比为35.45%~49.76%、干质量平均占比为38.77%~50.64%,割手密在伸长后期根系生物量占比最高,其次是同时期的品种A;宿根伸长期根鲜质量平均占比为28.07%~33.22%、干质量平均占比为29.56%~35.03%,根系生物量占比较新植伸长期减少。在30°~45°范围内,新植伸长期根鲜重平均占比为28.72%~32.78%、干质量平均占比为28.67%~31.31%,低于0°~30°范围的生物量;宿根伸长期根鲜质量平均占比为31.36%~40.11%、干质量平均占比为30.24%~37.51%,根系生物量占比在宿根伸长期除斑茅略微减少外较新植伸长期均增加。在45°~65°范围内,新植伸长期根鲜质量平均占比为20.57%~33.13%、干质量平均占比为20.69%~30.68%,宿根伸长期根鲜质量占比为31.83%~40.23%、干质量平均占比为29.62%~34.73%,根系生物量平均占比在宿根伸长期较新植伸长期均增加。总体来看,5个试验材料新植伸长期根系生物量平均占比在0°~30°范围内最高;宿根伸长期3个甘蔗品种根系生物量平均占比在30°~45°范围内最高,斑茅、割手密宿根伸长期根鲜质量平均占比在45°~65°范围内最高、干质量在0°~30°范围内最高。
本研究分析了5个材料的地上部分及根系生物量、根长、根表面积、根体积、根尖数、分叉数、交叉数与甘蔗宿根性之间的相关性(表6)。分析结果显示,与宿根性相关性最高的是新植的与竖直方向呈0°~30°范围内的根表面积、根体积、根长,其次是根总数、0°~30°范围内的根鲜质量和分叉数,以及根总鲜质量。从宿根和综合分析整体上看,与竖直方向呈0°~30°夹角范围内的根鲜质量与宿根性的相关性最高,其次是0°~30°范围内的根系形态,而新植伸长期0°~30°范围内的根表面积与宿根性相关性最高(0.894)。新植和宿根伸长期3个角度范围内根系和宿根性的相关性大小为0°~30°>30°~45°>45°~65°。
甘蔗宿根性是新植甘蔗砍收后维持连续多次收获产量的稳定性的能力,也称宿根能力。宿根性强则很大程度上表示除严重自然灾害以外,从宿根第一季后的宿根蔗较新植至少无明显减产或产量持平。甘蔗宿根年限是甘蔗宿根性的体现形式,宿根性强则宿根产量维持稳定,宿根年限长[40]。甘蔗宿根年限受到品种特性、土壤条件、种植管理方式、气候等因素的影响[41]。随着宿根年限的增加,蔗蔸的位置会升高,根系变浅,宿根蔗抗倒伏能力减弱,同时加上病虫害和冬春少雨干旱,地下芽活性降低,极有可能导致地下芽萌发率降低[1,41]。宿根萌发期主要在春季,降雨少,而新根系较少且主要分布在表层土壤中,对深层土壤中的水分吸收只能靠上季留下的深根系[42]。在本研究中,宿根性强的材料在与竖直方向夹角0°~30°范围内根系生物量和数量分布较高,甘蔗品种的深根系对来年地下芽萌发起到关键作用,因此深根系很有可能促进了宿根蔗蔸活力的保持。
甘蔗的强宿根性状主要来自野生种质,目前主要来自割手密,在育种技术成熟后,甘蔗野生种质的许多强宿根优良性状可以整合到现有优良亲本中,使我国甘蔗宿根年限短的问题得以解决。而在本研究中,甘蔗品种、斑茅、割手密的根系在数量和密集程度上有较大差别:斑茅和割手密的单丛根系生物量和数量均远高于甘蔗品种,但单株较低。值得注意的是,斑茅的根系相对于另外2个材料是最密集的,由于斑茅的丛生性较好,植株在每丛中生长较为紧密,因此其根系也较其余2个材料更显密集。另外,根据2 a的试验观察,斑茅根系有一个极为明显的特征:其根系能够长期保持活力,无明显的褐化死亡的现象,其根系近植株茎杆端表皮、皮层细胞死亡后裂解为灰白色薄片紧贴于内皮层,而割手密和甘蔗根系上述部位根系表皮、皮层死亡后则有明显的变黑褐化,同时并非紧贴于有活性的内皮层而是留有较大空隙,且相对于另外2个材料斑茅根系皮层包裹部分木质化程度较高,表现为强度较大、弯曲度较小且直径较大,这很可能是其地上部生物量较高的原因之一。本研究中割手密根系相对于甘蔗和斑茅最大的特点是有较大部分根系着生于地下横走茎的节上,其分布以地下茎的生长方向为主导,致使割手密根系分布相对较广,便于吸收远端和更深土层的水分和矿质养分,但现有甘蔗品种在筛选过程中似乎未获得地下横走茎性状。甘蔗根系则以向上生长的节为主导,每个节上着生的根形呈伞状分布,越接近于茎的初始萌发基部,其根越密集,且同斑茅和割手密的共同点则是在地上部分收获后,根系能保持活力,直至新根系替代其功能。上述斑茅、割手密和甘蔗根系的特点及相关性状有待后续进一步研究,以期培育出宿根能力更强的甘蔗品种。
高茎率可以成为筛选甘蔗宿根性的指标,宿根分蘖数常被作为评价相关材料宿根性的指标,分蘖力强的材料,可以促进分蘖成茎,获得更多的有效茎数量[2,43-44]。在本研究中,新植和宿根2季的割手密和斑茅表现为分蘖多且成茎率高,其株数从伸长初期到伸长后期无明显变化,而相比之下甘蔗品种的株数在伸长初期较多,但到伸长后期会有明显减少,显然有许多无效分蘖消亡,成茎率较低。因此,在评价甘蔗品种宿根性时,需要考虑宿根与新植相比的发株率和生物量外[3],成茎率高也是强宿根甘蔗品种的表现之一。同时,宿根性好的品种,其在宿根季表现出较高的生物量[45],本研究的3个甘蔗品种中,宿根性较强的甘蔗品种A、B地上部分生物量也证实了这一点。而割手密的地上部分生物量则有所不同,表现出其强宿根的主要性状则是其充满活力的地下横走茎和宿根季分布较为均匀的根系。
根系在作物的整个生长发育过程中起着关键作用[46],MILLIGAN等[44]研究表明,旺盛的根系是甘蔗宿根性强的标志之一,可以增强对土壤中养分的吸收利用,除此之外,蔗蔸形态[43]、宿根季甘蔗有效茎数量、宿根季产量等也被认为是评定宿根性的主要指标。本研究中,相关性分析发现,在整体上,与竖直方向呈0°~30°夹角范围内的根鲜质量与宿根性的相关性最高(r=0.805**),其次是0°~30°范围内的根系形态。说明甘蔗强宿根性与0°~30°范围内根系的各项指标有着极大的关系。新植蔗是宿根的基础,有趣的是新植的0°~30°范围内的根系形态指标与宿根能力的相关性接近于0.900,明显高于宿根季也高于综合相关性,表明该指标可作为强宿根性的代表性指标,可以通过评价新植蔗与竖直方向呈0°~30°夹角范围内的根系相关性状指标得出宿根能力的评价,比如与竖直方向呈0°~30°夹角范围内的根鲜质量指标。另外,通过分析发现,伸长期斑茅宿根与新植的平均单条根鲜质量比值非常接近于1,同时强宿根品种A的比值为0.13/0.14,品种B的为0.12/0.20,品种C的为0.12/0.27,强宿根割手密为0.14/0.26,不同于强宿根甘蔗和斑茅接近于1,很可能是因为它有地下横走茎的生长模式。因此,甘蔗品种宿根与新植的平均单条根鲜质量比值若接近于1或是出现横走茎则极有可能是强宿根种。
保持活力的深根群可能是甘蔗宿根季前期甘蔗萌发早、生长快的重要因素之一,不同宿根性甘蔗品种之间,以及斑茅和割手密之间的根系,在不同生长角度范围内的生物量、数量以及占比分布存在差异。综合分析可得,不同甘蔗品种、斑茅和割手密的根系生长分布和生长模式存在差异和共同点,宿根能力与根系分布及生长模式密切相关,割手密与斑茅、甘蔗品种的差异在于割手密特有的地下横走茎;斑茅与割手密、甘蔗品种之间的差异在于斑茅根系密集度高、强度大及活力的长期保持;甘蔗材料间宿根性的差异在于伸长中后期根系生物量、根数量以及宿根蔗与新植蔗的平均单条根鲜质量比值。上述指标可为筛选强宿根材料提供一定依据,同时与竖直方向呈0°~30°夹角范围内的根鲜质量等性状,以及地下横走茎的有无,在新植蔗阶段评价宿根能力方面可能有一定的应用前景,并需要进一步研究和验证。
