在控制环境的温室中,种了9个代表一系列成熟型的陆地棉品种。根据表达棉花形态生长对生理时间(累积热单位)的反应的方程式所作的分析指出,主茎节产生速度的差异为15%,果座产生速度的差异为23%,铃期的差异为3.5日以及第一果枝节的差异为1.5。在主茎节产生速度、果座产生速度和铃期方面,各品种之间的差异显著。主茎节产生速度和果座产生速度方面各品种的排列次序与主观上对成熟型的排列是相同的。田间数据的分析表明,棉花各品种的排列可以根据果座产生速度或开花速度,或根据由所发现的方程式而计算的垂直开花间期。
In the controlled environment of the greenhouse, planted a series of nine mature varieties of upland cotton. An analysis based on an equation expressing the response of cotton morphology to physiological time (cumulative heat unit) indicated that the difference in speed of production of main stems was 15%, the difference in the speed of fruit set generation was 23%, and the difference in ringing periods was 3.5 days And the difference of the first branch is 1.5. There were significant differences among the cultivars in terms of speed of production of main stems, speed of production of bolls and boll number. The order of arrangement of the varieties in terms of the speed of production of main stems and the speed of production of fruit bases is the same as the subjective arrangement of mature types. Analysis of the field data shows that the arrangement of the cotton varieties can be based on the speed at which the fruit is produced or the rate of flowering, or on the vertical flowering interval calculated from the equation found.
