烯效唑对低氮水平下红小豆生长和产量的影响
Effects of Uniconazole on Growth and Yield of Adzuki Beans under Low Nitrogen Conditions
摘要
Abstract
To investigate the regulatory effects of uniconazole on the growth and yield of adzuki bean under low nitrogen level,two adzuki bean cultivars,Pearl Red(small-grained cultivar)and Ji Hong 352(large-grained cultivar),were selected as test materials.The 50 mg·L-1 uniconazole solution was used as the exogenous regulator.A pot culture method was adopted to simulate low nitrogen environment,with two nitrogen levels set:low nitrogen treatment(N1:pure N 28.8 kg·hm-2)and conventional fertilization control(N2:pure N 57.6 kg·hm-2).Foliar spraying of uniconazole was conducted at the initial flowering stage.Key physiological indices including morphological characteristics,photosynthetic characteristics,and carbon-nitrogen metabolism of adzuki bean were deter-mined to clarify the regulatory effects of uniconazole on the growth and yield under low nitrogen level.The results showed that foliar application of 50 mg·L-1 uniconazole significantly increased the net photosynthetic rate of adzuki bean under low nitrogen level,with the net photosynthetic rate of Zhenzhuhong and Jihong 352 increased by 25.06%and 11.46%,respectively.Meanwhile,uniconazole enhanced the carbon-nitrogen metabolism capacity of adzuki bean;the fructose content of Zhenzhuhong and Jihong 352 increased by 21.24%and 23.33%,respectively.It further promoted plant growth and biomass accumulation,and ultimately improved the yield of adzuki bean.关键词
