Abstract

The effect of growth regulators Albite and Emistim R and pesticide Bunker on the leaf area of spring soft wheat variety Bazhenka and the content of photosynthetic pigments were studied at the substation of the Northeast Federal Agricultural Research Center (FARC) under the conditions of the Kirov region in 2017 and 2019. Using the growth regulator Emistim R alone and in a tank mixture with the fungicide Bunker and the growth regulator Albite in combination with the fungicide for seed treatment, the maximum concentration of chlorophyll a and b in the flag leaf (9.1–9.4 and 5.1–6.6 mg/g of dry weight, respectively) and the highest yield (3.1, 3.5, and 3.0 t/ha, and 1.7 t/ha in the control) was observed. The significant effect of the flag leaf area per yield (r = 0.58), Chl a and b concentration, and the number of grains per head (r = 0.58; r = 0.57) was determined. The pigment content during the period from emergence to heading was affected by temperature (Chl a (r = –0.89), Chl b (r = –0.81), and carotenoids Car (r = –0.79)) and precipitation (Chl a (r = 0.90), Chl b (r = 0.85), and Car (r = 0.86)). The negative correlations with precipitation and positive correlations with temperature were detected for the leaf area of the main stem and subflag leaf.

生长调节剂作用下春小麦品种Bazhenka光合装置的形成

摘要

在基洛夫地区的条件下，在东北联邦农业研究中心（FARC）的变电站研究了生长调节剂Albite和Emistim R以及农药Bunker对春季软小麦Bazhenka叶片面积和光合色素含量的影响。在2017年和2019年。单独使用生长调节剂Emistim R，并与杀真菌剂Bunker和生长调节剂Albite混合使用，与杀真菌剂混合使用进行种子处理时，旗叶中叶绿素a和b的最大浓度（9.1–观察到干重分别为9.4和5.1-6.6 mg / g）和最高产量（对照中分别为3.1、3.5和3.0 t / ha和1.7 t / ha）。旗叶面积/单产的显着影响（r= 0.58），Cla和b的浓度以及每头的晶粒数（r = 0.58; r  = 0.57）。从发芽到抽穗期的色素含量受温度（Chl a（r = –0.89），Chl b（r = –0.81）和类胡萝卜素Car（r = –0.79）的影响和沉淀（Chl a（r = 0.90），Chlb（r = 0.85）和Car（r = 0.86））。在主茎和次旗叶的叶面积上发现与降水的负相关，与温度成正相关。
