以白木香[Aquilaria sinesis (Lour.) Spreng.] 6个不同种质（3个已认定良种：海香1号、海香2号、海香3号；3个待审品种：皮油种、大叶种、囊泡种）为研究对象，其中皮油种来源于广东省揭阳市，大叶种来源于海南省定安县，其余均来源于海南省文昌市。分别采用GB/T 6043—2009《木材pH的测定》、蒽酮比色法、考马斯亮蓝法和硝酸-乙醇法测定树干木材的pH、淀粉含量、可溶性糖含量、可溶性蛋白含量和纤维素含量，并利用SPSS 26.0软件对以上5个指标的测定结果进行方差分析、多重比较（沃勒邓肯法、LSD法）分析和Pearson相关性分析。结果表明：白木香6个不同种质树干木材均为酸性，pH为5.40~6.06（海香3号最高，大叶种最低）；淀粉含量为13.16~33.85 mg/g（大叶种含量最高，海香3号含量最低）；可溶性糖含量为3.60~20.16 mg/g（大叶种含量最高，海香1号含量最低）；可溶性蛋白含量为0.17~0.25 mg/g（海香1号含量最高，皮油种含量最低）；纤维素含量为0.46~0.61 g/g（海香1号含量最高，海香2号含量最低）。白木香不同种质树干之间的pH、淀粉含量、可溶性糖、纤维素含量存在显著性差异（P<0.05），而可溶性蛋白含量无显著差异。pH与可溶性糖含量、淀粉含量之间均呈极显著负相关（P<0.01）；淀粉含量和可溶性糖含量之间呈极显著正相关（P<0.01）；可溶性蛋白、纤维素含量与其他生理指标无显著相关关系。

Abstract

Six different germplasms of Aquilaria sinesis (Lour.) Spreng. (three approved improved varieties: Haixiang 1, Haixiang 2 and Haixiang 3, and three pre-varieties: Piyou type, Big leaf type and Nangpao type) were used as the research objects. Among them, Piyou type came from Jieyang city, Guangdong province, Big leaf type species came from Ding'an county, Hainan province, and the rest came from Wenchang city, Hainan province. The pH, starch content, soluble sugar content, soluble protein content and cellulose content of the wood from trunk were determined by GB/T 6043—2009 (Determination of wood pH), anthrone colorimetric method, Coomassie bright blue method and nitric acid-ethanol method respectively. SPSS 26.0 was used to conduct variance analysis, multiple comparison analysis (Waller-Duncan method, LSD method) and Pearson correlation analysis on the measurement results of the above five indicators. The test results indicated that the wood from the trunk of six different A. sinensis germplasms were acidic, and the pH ranged from 5.40 to 6.06. The pH of the trunk was the highest in Haixiang 3 and the lowest in Big leaf type. The starch content ranged from 13.16 to 33.85 mg/g. Among them, the trunk starch content of Big leaf type was the highest, and that of Haixiang 3 was the lowest. The soluble sugar content ranged from 3.60 to 20.16 mg/g. Among them, the trunk soluble sugar content of Big leaf type was the highest, and that of Haixiang 1 was the lowest. The soluble protein content ranged from 0.17 to 0.25 mg/g. Among them, the trunk soluble protein content of Haixiang 1 was the highest, and that of Piyou type was the lowest. The cellulose content ranged from 0.46 to 0.61 g/g. Among them, the trunk cellulose content of Haixiang 1 was the highest, and that of of Haixiang 2 was the lowest. The analysis results indicated that there were significant differences in pH, starch content, soluble sugar and cellulose content among different A. sinensis germplasms (P<0.05), but no significant differences in soluble protein content. There was a very significant negative correlation between pH and soluble sugar content, starch content (P<0.01). There was a very significant positive correlation between starch content and soluble sugar content (P<0.01). The content of soluble protein and cellulose content had no significant correlation with other physiological traits. This study could provide basic data for varieties breeding, upgrading and adjustment of planting industrial structure, DUS test guidelines and so on.
