种茎贮藏和浸水时间对木薯种苗抗旱性的影响
Effects of Seed-stem Storagea nd Soaking Time on Drought Resistance of Cassava Seedlings
摘要
Abstract
The effects of different seed-stem storage time (0, 7 and 14 d) and various water-soaking time (0, 2, 4, 6 and 8 h) on the drought resistance of seedlings of cassava variety SC 124 were studied.The results showed that:there was a very sig-nificant negative correlation between seed-stem storage time and survival rate; the significant interaction of storage time and soa-king time existed in survival rate,dry tuber yield , and starch yield;soaking the fresh seed-stems could reduce survival rate and yield;soaking the preserved seed-stems for a short time was beneficial to the increase in survival rate , dry tuber yield , and starch yield of cassava;for the seed-stems preserved for 7~14 days, the 2-h soaking treatment could enhance both dry tuber yield and starch yield by over 11.0%in comparison with the not-soaking treatment.关键词
