国外过去曾有阶段发育理论,把冬性禾谷类作物,因低温而引起的发育现象,称为“春化现象”,把接受低温诱导发育的阶段称为“春化阶段”。自从这一理论创立后,国内外许多学者曾作了大量的研究,对这一理论进行了充实。研究较多也较深入,但对于在田间条件下,从幼穗分化过程中确定完成春化指标,虽然冲破了过去认为是主茎生长锥伸长的传统认识,但并没有统一一个指标,各说不一。黄敬芬等提出以小穗原基出现为标志,季书勤等又提出春性品种以伸长期为标志,过渡型品种和冬型品种以二棱期通过为标志。本文以贵州小麦垂直生态研究遵义协作点资料进行分析。 In the past, there was a theory of stage development in foreign countries. The development of winter cereal crops due to low temperature was called the “vernalization phenomenon” and the stage of development induced by low temperature was called the “vernalization stage.” Since the founding of this theory, many scholars at home and abroad have made a great deal of research and enriched this theory. The research is more and more in-depth, but in the field conditions, from the panicle differentiation process to determine the completion of the vernalization index, although broke through the past considered the main stem growth cone elongation of the traditional understanding, but there is no unification of an indicator Different. Huang Jingfen proposed the emergence of spikelet primordium as a symbol, Ji Shuqin also proposed spring varieties to elongation period as a symbol, transitional varieties and winter varieties to the two-ridge period for the sign. In this paper, Guizhou wheat vertical ecological research Zunyi collaboration point data analysis.
