Effect of Different Treatments on Seed Germination Characteristics of Lagerstroemia minuticarpa
摘要
Abstract
To investigate the seed germination characteristics of Lagerstroemia minuticarpa,three treatments were designed:seed soaking duration,culture temperature,and storage duration.The study examined the effects of these treatments on seed germination capacity,aiming to provide reference value for the conservation of Lagerstroemia minuticarpa germplasm resources.The results showed:(1)The germination percentage and germination index of Lagerstroemia minuticarpa seeds at different soaking times were significantly different(P<0.05),Germination percentage,germination potential,and germination index in descending order:24 h>48 h>0 h.The germination of the seeds could reach 50.67%when the soaking time was 24 h.(2)The germination rate and germination index of Lagerstroemia minuticarpa seeds at different incubation temperatures were significantly different(P<0.05),and seed germination was significantly affected by temperature.At 25℃,the highest germination rate of Lagerstroemia minuticarpa seeds was 50.67%.The order of germination rates,from the highest to the lowest was:25℃>15℃>25/15℃.(3)Storage time had a significant effect on germination of Lagerstroemia minuticarpa seeds.Overall,the germination rate,germination potential,germination index in the order of size were shown as:the current year seed>1 year seed>2 years old seed.Under the conditions of 25℃germination temperature and 24 h immersion,the germination rate,germination potential and germination index of the current year's seed and 1 year seed were significantly higher than those of the 2 years old seed(P<0.05),and the difference reached a highly significant level(P<0.01).关键词
