前言开花是小麦重要的生物学特性之一。充分了解小麦的开花习性对于掌握小麦产量形成规律,提高栽培技术、选配亲本、适时杂交、培育适应性强、丰产性好的新品种都有指导意义。品种的特性和气候条件决定了该品种开花时期。据我们观察,每个品种的开花高峰期不同,在一天内达到高峰期的时间也不一样。阿勃,晋2148、高原338开花高峰集中在湿度大,温度较高的午后,说明这些品种开花时对温、湿度变化的要求较高,但墨波品种一日内开花频率变化很小,表明它较其他三个品种对温、湿度变化的要求不严,正
Introduction Flowering is one of the important biological characteristics of wheat. To fully understand the flowering habits of wheat is of guiding significance in grasping the law of wheat yield formation, raising cultivation techniques, matching parents, timely crossing, and cultivating new varieties with strong adaptability and high yield. Variety of characteristics and climatic conditions determine the variety of flowering period. According to our observation, the peak flowering period of each species is different, and the peak time in one day is not the same. Abercrombie and Fitch, Jin 2148, plateau 338 flowering peak concentrated in the humidity, high temperature in the afternoon, indicating that these varieties of flowers when the temperature and humidity changes higher, but the variety of varieties of flowers within one day of small changes in flow rate, indicating that it More than the other three varieties of temperature and humidity changes in the lax, positive
