Abstract

A new plant growth stimulant was developed according to the technology engineered by the scientists of ITMO and SPBGAU Universities. The biological effectiveness of the preparation was assessed by measuring 20 wheat productivity parameters and 16 parameters of various types of pathogenesis formed during the progress of root rot caused by Helminthosporium, different types of rust, powdery mildew, and wheat leaf blotch. Application of the stimulant promoted a potential yield increase in 64% of samples (statistically significant at P < 0.05 in 28% of samples). Among the essential parameters of the yield formula, the preparation exerted the most remarkable action on spike length, the number of spikelets per spike, number of grains per spike, and weight of grains in one spike. Foliar spraying of plants with the protein growth stimulant promoted an increase in total nitrogen content of wheat leaves by an average of 84.6% in 92% of samples. Wheat grains exhibited better characteristics with the application of the protein stimulant compared to the control according to the results of microfocus X-ray radiography and optical analysis. The use of the protein growth stimulant delayed the progress rate of Helminthosporium root rot by an average of 60%, powdery mildew by 5% (based on the number of spots and their area by 36 and 52%, respectively), brown rust by 2.9% (based on the number of pustules per leaf by 76.8% and pustule area by 79.7%), and wheat leaf blotch by 15.9% compared with the control. The stimulant effectiveness has been found to depend strongly on wheat variety. Thus, the prospects of using the new, effective plant-growth stimulant to increase wheat productivity and protect against diseases have been shown experimentally. Further research is necessary due to the heterogeneity of outcomes in experiment variations.

使用微焦点X射线和光学成像技术刺激蛋白质生长以提高小麦产量和评估谷物品质的生物学原理

摘要

根据ITMO和SPBGAU大学的科学家设计的技术，开发了一种新的植物生长刺激剂。通过测量20种小麦生产力参数和16种在蠕虫，根锈病，不同类型的铁锈，白粉病和小麦叶片斑点引起的根腐病进展过程中形成的各种发病机理的参数来评估该制剂的生物学有效性。施加刺激剂可提高64％样品的潜在产量增加（在P值上具有统计学意义<0.05（在28％的样本中）。在产量公式的基本参数中，该制剂对穗长度，每个穗的穗数，每个穗的晶粒数和一个穗的晶粒重量发挥了最显着的作用。用92％的样品对植物进行叶面喷洒蛋白质生长促进剂后，小麦叶片总氮含量平均提高了84.6％。根据微聚焦X射线射线照相和光学分析的结果，与对照相比，使用蛋白质刺激剂时，小麦籽粒表现出更好的特性。蛋白质生长刺激剂的使用延迟了蠕虫孢子的进展速度根腐平均减少60％，白粉病减少5％（分别基于斑点和面积的36％和52％），褐锈病减少2.9％（基于每片脓疱的数量减少76.8％）与脓疱面积相比，减少了79.7％），小麦叶片斑点比对照组减少了15.9％。已发现刺激效果在很大程度上取决于小麦的品种。因此，实验证明了使用新型有效的植物生长刺激剂来提高小麦产量并预防疾病的前景。由于实验变异结果的异质性，因此有必要进行进一步的研究。
