To clarify the influence of exogenous alpha-ketoglutaric acid (α-KG) spraying after anthesis on the photosynthesis of wheat flag leaves and the characteristics of grain filling, Shumai 830 and Shumai 1868, with significant differences in thousand-grain weight, were selected as materials. Using no spraying as the contrel (CK), 0.50, 0.75, and 1.00 g·L-1 concentrations of α-KG spraying at 0 d and 15 d after anthesis were set up. The differences in chlorophyll content and photosynthetic parameters of flag leaves, grain-filling parameters, and yield under different treatments were compared. The results indicated that compared with the CK, the α-KG treatment enhanced wheat photosynthesis and promoted grain filling, thereby increasing the grain weight of wheat. Among them, the treatment of 0.75 g·L-1 α-KG showed the best effects. Under the treatment with 0.75 g·L-1 of α-KG, the chlorophyll content at 21 d after anthesis and the net photosynthetic rate at 20 d after anthesis of Shumai 830 and Shumai 1868 were significantly higher than those of the CK, with an increase rate of 12.0% and 9.6% for chlorophyll content, and 11.1% and 6.6% for net photosynthetic rate, respectively. And the active grain-filling period, average grain-filling rate, and maximum theoretical thousand-grain weight of Shumai 830and Shumai 1868 were significantly higher than those of the CK, with an increase rate of 3.8%, 4.6%, and 7.9% for Shumai 830, and 1.6%, 4.9%, and 4.9% for Shumai 1868. After the treatment with 0.75 g·L-1 of α-KG, the thousand-grain weight of Shumai 830 and Shumai 1868 was increased by 3.8% and 2.7%, respectively, compared with CK, and the yield was increased by 6.2% and 7.9%, respectively, all showing significant difference from the CK. Thus, exogenous α-KG spraying after anthesis can promote photosynthesis and grain filling by increasing the chlorophyll content of wheat, and ultimately increase grain weight and yield.

为明确花后外源α-酮戊二酸(α-KG)对小麦旗叶光合及籽粒灌浆特性的影响,以千粒重差异较大的品种蜀麦830和蜀麦1868为材料,设置0.50、0.75和1.00 g·L-13个α-KG喷施浓度(于开花第0天和花后第15天喷施),以不喷施α-KG为对照(CK),分析不同处理下小麦旗叶叶绿素含量、光合参数、籽粒灌浆参数及产量的差异。结果表明,与CK相比,α-KG处理均能提高小麦光合作用,促进籽粒灌浆,从而增加小麦粒重,其中0.75 g·L-1 α-KG处理效果最佳。0.75 g·L-1 α-KG处理下,蜀麦830和蜀麦1868花后21 d的叶绿素含量和花后20 d的净光合速率较CK均显著提高,其中叶绿素含量增幅分别为12.0%和9.6%,净光合速率增幅分别为11.1%和6.6%;灌浆活跃期、平均灌浆速率、最大理论千粒重较CK均显著增加,蜀麦830的3个参数增幅分别为3.8%、4.6%和7.9%,蜀麦1868的增幅分别为1.6%、4.9%和4.9%。0.75 g·L-1 α-KG处理下蜀麦830和蜀麦1868的千粒重较CK分别增加3.8%和3.4%,产量分别增加了6.2%和7.9%,均与CK差异显著。由此可见,花后喷施外源α-KG能通过增加小麦叶绿素含量促进光合作用和籽粒灌浆,最终增加粒重和产量。

为明确花后外源α-酮戊二酸(α-KG)对小麦旗叶光合及籽粒灌浆特性的影响,以千粒重差异较大的品种蜀麦830和蜀麦1868为材料,设置0.50、0.75和1.00 g·L-13个α-KG喷施浓度(于开花第0天和花后第15天喷施),以不喷施α-KG为对照(CK),分析不同处理下小麦旗叶叶绿素含量、光合参数、籽粒灌浆参数及产量的差异。结果表明,与CK相比,α-KG处理均能提高小麦光合作用,促进籽粒灌浆,从而增加小麦粒重,其中0.75 g·L-1 α-KG处理效果最佳。0.75 g·L-1 α-KG处理下,蜀麦830和蜀麦1868花后21 d的叶绿素含量和花后20 d的净光合速率较CK均显著提高,其中叶绿素含量增幅分别为12.0%和9.6%,净光合速率增幅分别为11.1%和6.6%;灌浆活跃期、平均灌浆速率、最大理论千粒重较CK均显著增加,蜀麦830的3个参数增幅分别为3.8%、4.6%和7.9%,蜀麦1868的增幅分别为1.6%、4.9%和4.9%。0.75 g·L-1 α-KG处理下蜀麦830和蜀麦1868的千粒重较CK分别增加3.8%和3.4%,产量分别增加了6.2%和7.9%,均与CK差异显著。由此可见,花后喷施外源α-KG能通过增加小麦叶绿素含量促进光合作用和籽粒灌浆,最终增加粒重和产量。

To clarify the influence of exogenous alpha-ketoglutaric acid (α-KG) spraying after anthesis on the photosynthesis of wheat flag leaves and the characteristics of grain filling, Shumai 830 and Shumai 1868, with significant differences in thousand-grain weight, were selected as materials. Using no spraying as the contrel (CK), 0.50, 0.75, and 1.00 g·L-1 concentrations of α-KG spraying at 0 d and 15 d after anthesis were set up. The differences in chlorophyll content and photosynthetic parameters of flag leaves, grain-filling parameters, and yield under different treatments were compared. The results indicated that compared with the CK, the α-KG treatment enhanced wheat photosynthesis and promoted grain filling, thereby increasing the grain weight of wheat. Among them, the treatment of 0.75 g·L-1 α-KG showed the best effects. Under the treatment with 0.75 g·L-1 of α-KG, the chlorophyll content at 21 d after anthesis and the net photosynthetic rate at 20 d after anthesis of Shumai 830 and Shumai 1868 were significantly higher than those of the CK, with an increase rate of 12.0% and 9.6% for chlorophyll content, and 11.1% and 6.6% for net photosynthetic rate, respectively. And the active grain-filling period, average grain-filling rate, and maximum theoretical thousand-grain weight of Shumai 830and Shumai 1868 were significantly higher than those of the CK, with an increase rate of 3.8%, 4.6%, and 7.9% for Shumai 830, and 1.6%, 4.9%, and 4.9% for Shumai 1868. After the treatment with 0.75 g·L-1 of α-KG, the thousand-grain weight of Shumai 830 and Shumai 1868 was increased by 3.8% and 2.7%, respectively, compared with CK, and the yield was increased by 6.2% and 7.9%, respectively, all showing significant difference from the CK. Thus, exogenous α-KG spraying after anthesis can promote photosynthesis and grain filling by increasing the chlorophyll content of wheat, and ultimately increase grain weight and yield.
