1980—1981年我们在本院试验田(合肥市西郊)对太谷核不育小麦开花习性和杂交技术进行了初步研究,现将结果报告于下。一、开花习性每日开花时间于4月26—27日连续观察两天,从早晨6时开始,每小时观察一次,到下午18时结束。每次观察所开之花(指小穗基部两朵小花)均用剪刀将其颖壳剪去一半,以识别和记载开花数。与此同时,用通风干湿球温度表记载株间的温湿度,以观察开花与气象条件的关系。一穗开花日数及一穗每日开花数,则固定样株、挂牌,逐日记载。一株开花所需日数及一株、一穗开花顺序和开花状况等,均选株挂牌,进行观察。
From 1980 to 1981, we conducted a preliminary study on the flowering and crossbreeding techniques of Taigu nuclear sterile wheat in our experimental field (western suburbs of Hefei). The results are reported below. First, flowering habits Daily flowering time in April 26-27 consecutive observation of two days, starting from 6 am, observed once an hour, to 18:00 ended. Each observation of the open flowers (referring to the two small flowers at the base of the spikelets) scissors are used to cut its husk half, to identify and record the number of flowering. In the meantime, the temperature and humidity between the strains were recorded by a ventilated dry-bulb thermometer to observe the relationship between flowering and meteorological conditions. A day of flowering and a spike of a flowering number of spikes, the fixed sample, listing, recorded daily. The number of days and a flower required for flowering, a flowering order and flowering, etc., were selected strains listed for observation.
