不同品种金银花生长过程中生理性状变化研究

Study on Physiological Trait Changes in Growth Process of Different Varieties of Lonicera japonica

目的:了解不同品种金银花生长过程中生理性状变化,掌握金银花的生长规律。方法:观察研究3个品种金银花的生长发育过程中花蕾长度、颜色、折干率和开花率等的变化,并运用SPSS非线性回归分析得出金银花生长模拟曲线方程。结果:不同品种之间以及同一枝条不同节位之间金银花生长均呈现相似规律,折干率均在三青期呈现最大值,二白期百花重最大,且品种间无差异。筛选的两个曲线方程拟合度分别为0.996、0.995。结论:本研究所得曲线能很好地反应金银花的生长规律,较系统的研究了金银花生长过程,能很好的应用于农业生产的指导。

Objective ： To study the physiological trait changes in the growth process of different varieties of Lonicera japonica, and to explore the growth regularity. Methods：Length, color, flowering rate and drying rate in the growth and development process of different varieties of Lonicera japonica were observed. Nonlinear regression analysis was used to conclude the growth simulation curve equation. Results ： Among different varieties and different sections of the same branch, the growth showed a similar law, the drying rates of the＇ sanqing＇ period got the maximum value in all of the three varieties, the weight of the flower in ＇ erbai＇ period was the highest, and no differences between varieties. The R2 of the two curve equations was O. 996 and 0. 995, respectively. Conclusion ： Both of two curve e- quations can reply the growth regularity of Lonicera japonica flower very well. Study on the growth process systematically can guide the agricultural production very well.
