1988~1990年,用过渡型小麦品种在黑河、呼和浩特、兰州、乌鲁木齐进行早春播,在西南冬播麦区的昆明和贵阳进行早播,生长发育均正常。与当地春型小麦品种相比,成熟期因各地生态条件不同而有差别。在营养生长、营养生长和生殖生长并进、生殖生长这三大生育阶段中,过渡型小麦品种在黑河、呼和浩特、兰州、乌鲁木齐表现长—短—长的“两长一短”现象,而在昆明和贵阳则表现“三长”现象。田间春化的温度条件较宽,在日均温0~15℃范围内均可。开花前,对日长要求不严格。生理拔节—抽穗期间的天数与同期间的“平均光温积”之间呈极显著负相关,表现温光互作效应。在一定温度范围内,抽穗—成熟天数与此期间日均温呈极显著负相关。与春型小麦品种相比,过渡型品种的千粒重较高。通过在我国非过渡地带试验,从生长发育上,过渡型小麦品种表现了较强的生态适应性
From 1988 to 1990, the transitional wheat cultivars were sowed in early spring in Heihe, Hohhot, Lanzhou and Urumqi, and were sowed in Kunming and Guiyang in winter sowing areas of southwestern China. The growth and development were all normal. Compared with the local spring wheat varieties, the maturity period varies due to different ecological conditions. In the three growth stages of vegetative growth, vegetative growth, reproductive growth and reproductive growth, the transitional wheat cultivars showed long-short-long “two long and one short” phenomena in Heihe, Hohhot, Lanzhou and Urumqi, And Guiyang is the performance of “three long” phenomenon. Field vernalization temperature is wide, the average daily temperature 0 ~ 15 ℃ range can be. Before flowering, the requirements of Japan are not strict. Physiological jointing - the number of days during heading was significantly negatively correlated with the “average photothermal product” during the same period, indicating the effect of temperature and light interaction. Within a certain temperature range, the number of heading-maturing days was significantly negatively correlated with the average daily temperature during this period. Compared with the spring wheat varieties, the transitional varieties have a high 1000-grain weight. Through the test of non-transitional zone in our country, the transitional wheat varieties showed strong ecological adaptability from the growth and development
