High Phosphorus Acquisition and Allocation Strategy Is Associated with Soybean Seed Yield under Water- and P-Limited Conditions

چکیده
Both water stress and P deficit limit soybean seed yield, but the effects of regimes application rates, their interaction on status, acquisition, partitioning, roles in yield performance have not been well-studied. Two genotypes (Huangsedadou (HD) Zhonghuang 30 (ZH)) with contrasting root dry weight (DW) were used to investigate formation under two (well-watered (WW) cyclic (WS)) three rates (0 (P0), 60 (P60), 120 (P120) mg kg−1 soil). The results show that increased supply shoot DW concentrations accumulations different organs. Cultivar ZH had a significantly higher than HD at P60 P120 WS P0 WW, lower WW. harvest index acquisition efficiency, HD. between treatments significant leaf stem concentration. partitioning leaves stems seeds was positively correlated efficiency WS. We conclude (1) adequate improved mobilization from maturity, which may yield; (2) high is coordination partition produce water- P-limited conditions.

This study was carried out to investigate the yield response of 2 soybean (Glycine max (L.) Merrill) cultivars to different planting dates and plant populations and to examine the relationships of seed yield with leaf area index (LAI) and total dry matter (TDM) during the vegetative and reproductive periods for planting dates, plant populations, and cultivars. Two soybean cultivars, A3127 (earl...
متن کاملUnderstanding and modeling the effect of temperature and daylength on soybean phenology under high-yield conditions
Temperature and photoperiod can be used to simulate soybean (Glycine max [L.] Merr) phenology because they serve as surrogates for complex biochemical pathways leading to the appearance of certain developmental stages at the whole plant level. We developed a soybean phenology model (SOYDEV) which utilizes non-linear temperature and photoperiod functions and separates floral induction and post-i...
