Abstract

In this work, we have studied the impact of ozonation, freezing down to liquid nitrogen temperature and their combination on sowing quality and crop yield for Dii cultivar beetroot seeds. The optimal moisture, ozone dose within the ozone-air mixture, and the exposure time, not reducing the germination rate, were determined. The ozonation, freezing, and their combined effect affected neither the seed germination in laboratory, nor biometric indices in a field. The seed freezing down to liquid nitrogen temperature was found to significantly increase its crop yield. Biochemical analysis of root crops showed all the ways of presowing treatment to reduce the content of total sugars and betanine. After freezing and ozonation, the amount of dry matter decreased, but after combined exposure it augmented. Ozonation and subsequent freezing lowered the content of ascorbic acid. Significantly reduced studied parameters did not reach the minimum values specific to this crop. Freezing and a combined impact of the studied factors on the seeds increased the nitrate content in root crops, which did not exceed the maximum allowable rate.

甜菜种子预处理的物理因素对播种质量和产量的影响

本研究研究了臭氧化、冷冻降至液氮温度及其组合处理对Dii品种甜菜根种子播种品质和产量的影响。在不降低发芽率的前提下，确定了臭氧-空气混合物的最佳湿度、臭氧剂量和暴露时间。臭氧化、冷冻及其综合作用对实验室种子萌发和田间生物特征指标均无影响。将种子冷冻至液氮温度可显著提高其产量。根茎作物的生化分析表明，播前处理可降低总糖和甜菜碱的含量。经冷冻和臭氧化处理后，干物质含量降低，但经复合暴露后，干物质含量增加。臭氧化和随后的冷冻降低了抗坏血酸的含量。显著降低的研究参数未达到该作物特有的最小值。冻害及多种因素对种子的综合影响使块根作物的硝酸盐含量增加，但未超过最大允许值。

期刊介绍： The Journal publishes the reviews and original papers on cryobiological and cryomedical research, in particular the elucidation of mechanisms of injuries occurring in biological objects and caused by the influence of low and ultra low temperatures; natural resistance of biologicals to cold and their recovery post effect; the development of effective methods of cryoprotection and technology of storage of biological resources under hypothermic and ultra low temperatures, application of hypothermia, cryotherapy and cryopreserved biologicals for treating various pathologies; cell and tissue based therapies and other issues of low-temperature biology and medicine, as well as development of devices and equipment for low temperature biology and medicine. The journal covers all topics related to low temperature biology, medicine and engineering. These include but are not limited to: low temperature storage of biologicals (human, animal or plant cells, tissues, and organs), including preparation for storage, thawing/warming, cell and tissue culturing etc. response of biologicals to low temperature; cold adaptation of animals and plants; utilisation of low temperature in medicine; experimental and clinical transplantation, cell and tissue based therapies; developing of cryobiological and cryomedical devices; organisation and functioning of low temperature banks etc.
