Effect of Light and Temperature under Different Sowing Date on Spring Soybean (Glycine max L. Merill)
摘要
Abstract
In order to probe the effect of light and temperature (ELT) on spring soybean, 19 spring soybean varieties bred from different locations arranging from N 22.7°to N 50. 2° were sowed on 4 dates(21th April, 15th May, 11th June, 1st July) in 2 years, respectively. Model of ELT on development, morphological traits and yield-related traits were erected, and by parameters in modles the ELT of ecological traits were analyzed and features of various ecological types were discussed further. The results showed that ELT shortened the growing days from emergence to initial flowering. At the first, second and third sowing date, ELT shortened the growing days from ending flowering to mature. At the fourth sowing date ELT extended the growing days from end flowering tomature. From emergence to initial flowering ELT increased plant height, number of nods in main stem and biomass, from initial flowering to end flowering ELT decreased plant height, number of nods in main stem and biomass, from end flowering to maturity ELT increased biomass. Under the first and second sowing date, by increasing 100-seed weight at stage from initial flowering to end flowering and pods number per plant and seed number per area in the period from end flowering to maturity, ELT increased yield per area. Under the fourth sowing date, by increasing seed number per area at stage from initial flowering to end flowering and pod number per plant and lO0-seed weight in the period from end flowering to maturity, ELT increased yield per area. For responding to ELT, varieties selected should grow slowly from merging to initial flowering and develop rapidly in floweringing stage. Ecological types for early sowing date should be characterized as middle and late maturity, high ratio of bearing pods and seeds in flowering stages and high rate of seed-filling. For ecological type suiting for late sowing date, seed-filling stage should be short, the ratio of bearing pods in fioweringing stage and that of bearing seeds in seed-filling stage should be high.关键词
