Abstract

The study investigates the effect of presowing treatment of spring wheat seeds (Triticum aestivum L.) with succinic and salicylic acids at concentrations of 10^–5 M and 10^–3 M with and without the use of a vacuum infiltrator. The obtained results showed a positive effect of seed treatment under conditions of vacuum pressure (0.9 atm, 15 min) on the development of coleoptile and seedling root on the seventh day of germination. In terms of the germination energy or vigor, exposure to a vacuum environment did not have a significant effect on the third day. In the stressful conditions of plant development under hyperthermia exposure, it was found that treatment of seeds with salicylic acid at a concentration of 10^–3 M in a vacuum environment ensured the best result in that it reduced the stress load by suppressing catalase activity. Succinic acid at a concentration of 10^–5 M proved to be the best option as a growth enhancer. In combination with the use of a vacuum environment, this treatment most significantly accelerated the development of the coleoptile and the root of the seedling on the seventh day of germination.

真空环境下天然有机酸预播处理春小麦种子（Triticum aestivum L.）对植物生长发育的影响

摘要

该研究调查了在使用或不使用真空渗透器的情况下，用浓度为 10 ^–5 M 和 10 ^–3 M的琥珀酸和水杨酸对春小麦种子 ( Triticum aestivum L.) 进行播种前处理的效果。所得结果表明，真空压力条件下（0.9 atm，15 分钟）的种子处理对发芽第七天胚芽鞘和幼苗根的发育具有积极作用。就发芽能量或活力而言，暴露于真空环境在第三天没有显着影响。在高温暴露下植物发育的应激条件下，发现在真空环境中用浓度为10-3M的水杨酸处理种子可^确保获得最佳结果，因为它通过抑制过氧化氢酶活性来减轻应激负荷。^{浓度为 10 –5} M的琥珀酸被证明是作为生长促进剂的最佳选择。与真空环境的使用相结合，这种处理在发芽第七天最显着地加速了胚芽鞘和幼苗根部的发育。
