摘要

摘要对3个玉米杂交种在低温条件下的种子萌发能力进行了研究。并对影响种子活力的胚芽长度、根长度和胚芽质量等因素进行了分析。暴露温度分别为25°C(对照)、6°C和5°C,分析杂交种为Olt、f376和Turda 201。研究是在实验室控制条件下进行的,所得结果表明温度因子对分析的参数有严格的依赖性。

Study of the Germination Capacity of Maize Seeds Exposed to Low Temperatures
Abstract In this paper, were studied three maize hybrids in terms of seed germination capacity when they were exposed to low temperatures. Also, some elements regarding the seed vigor were analyzed, namely the length of the coleoptile, the length of the root and the weight of the germ. Exposure temperatures were 25 ° C (control), 6 ° C and 5 ° C and the hybrids analyzed were Olt, F 376 and Turda 201. The researches were realized under laboratory controlled conditions, and the obtained results showed a strict dependence of the parameters analyzed by the temperature factor.
