摘要
研究了催芽温度对油葵芽苗菜发芽率、根长、根系活力和株高的影响。结果表明:30℃的催芽温度可显著地提高种子的发芽率;低温催芽则有利于根系的生长,促进根的伸长;而相对较高的催芽温度则提高了根系活力,促进了地上部的生长,使株高有所增加。
The effects of germination temperature on germination rate,root length,root activity and plant height of oil sunflower sprout seeding were researched in order to providing a theoretical basis for good quality and high-yield.The results showed that change-temperature had no significant effect on enhancing the germination percentage,while germination temperature of 30℃ could improve the germination percentage significantly.Accelerating germination under low-temperature could promote root growth,and relatively high germination temperature could enhance root activity and growth of aerial part.
