Abstract

This study is based on the early discovery that DCPTA has important regulation function to prevent mung bean flower and pod abscission, Spraying DCPTA at the initial flowering stage of mung bean has better effect than other commonly used plant growth regulators on reducing abscission of mung bean flowers and pods. It is further proved that it is an effective strategy to improve the yield of mung bean. Through the combination of pot experiment and field experiment, Spraying different plant growth regulators (PGRs) at the initial flowering stage of mung bean, study the effects of different plant growth regulators on agronomic traits, physiological and biochemical indexes and photosynthetic performance of mung bean, Lvfeng 2 and Lvfeng 5 mung bean varieties were used as materials, and spraying water at the initial flowering stage of mung bean was used as control. DCPTA and α-NAA were sprayed on the leaves. The morphological indexes of plant height were recorded, and determination of dry matter accumulation and photosynthetic indexes in different parts. The results showed that DCPTA could improve the plant height, main stem node number and leaf area of Lvfeng 5, and the fresh and dry weight of Lvfeng 5 could be significantly improved by DCPTA treatment. However, Taking “Lvfeng 2” as experimental material, the effect of different plant growth regulators on improving fresh and dry weight was not obvious. In terms of photosynthetic performance, each treatment of Lvfeng 5 can improve the photosynthetic performance related indicators, the comprehensive effect of DCPTA > α-NAA.
