不同处理方法对皂荚种子萌发及幼苗生长的影响
Effect of Different Methods on Seed Germination and Seedling Growth of Gleditsia sinensis
摘要
Abstract
[Objective] To shorten the dormancy time and improve the germination rate of Gleditsia sinensis seeds.[Method] The seeds were treated with concentrated sulfuric acid method,alkaline water method,hot water method,altemate hot and cold water method,sand paper method and stratification method to compare the influence on seed germination and seedling growth through the germination time,germination rate,plant height,root length,fresh weight and chlorophyll content.[Result] Germination rate of sandpaper and sulfuric acid methods was 84％,which was the highest.The seeds of sandpaper method germinated in 4 days,and germination time was the shortest.The root length of sandpaper method was the longest,that was 80.52 mm.The treatment of sulfuric acid had the highest chlorophyll content,which was 6.597 8 mg/g.Contrast treatment had obvious advantages in plant height.Plant fresh weight of sulfuric acid and sandpaper was the best.[Conclusion] It can be concluded that sandpaper and sulfuric acid method were the best ways to promote the germination and seedling growth of Gleditsia sinensis.关键词
