Study on seedling growth rhythm of Toona ciliate var.pubescens
摘要
Abstract
Based on periodic observation of different provenience, the seedling growth was analyzed by ANOV and the growth rhythm of seedling height was analyzed by contrast analysis. The correlation between the height and different seeding date for different seedlings of Toona ciliate var. pubescens was fitted out. The mathematical model of seedling growth was formulated using regression analysis. The results showed: ( 1 ) The fast growth period of one-year-old Toona ciliate var. pubescens appeared from July to September. The height of spring sowing seedlings was better than winter sowing seedlings. (2 ) There were significant differences in seedling growth for different provenience of the seeds, that the provenance from Yifeng was much better than the other provenience. (3) The reliability of the mathematical models of the height growth was simulated with Logistic curve equation, the R2 of model parameters was from 0. 950 to 0. 969, which could be applied to estimate and analyze the growth rate for one-year-old seedlings of Toona ciliate var. pubescens different growing stages.关键词
