保水剂与多效唑联合施用对木薯光合特性的影响
Effect of water-retaining agent and paclobutrazol on photosynthetic characteristics of cassava (Manihot esculenta Crantz)
摘要
Abstract
[Objective]Effect of water-retaining agent and paclobutrazol on photosynthetic characteristics of cassava was studied in order to provide scientific references for improving photosynthetic productivity and for promoting starch content and cassava yield. [Method]TPS-2 portable photosynthesis determination system, produced by American company PP-SYSTEM, was used to assess the influence of water-retaining agent and paclobutrazol on cassava photosynthetic characteristics under field conditions. [Result]By applying water-retaining agent, the net photosynthesis rate (Pn) of the upper leaves increased, hut the Pn of the middle and lower leaves decreased quickly. Paclobutrazol, which could delay the withering of lower leaves, affected around 15 leaves. [Conclusion]Combined application of water-retaining agent and paclobutrazol in cassava production could improve the net photosynthetic rate of the plant.关键词
