Effects of Seed Maturity of Turf-Type Tall Fescue on the Seed Vigor and the Optimal Harvesting Time
摘要
Abstract
By assay of accelerated aging germination, germination index, vigor index, seedling length,seedling weight, electric conductivity, dehydrogenase activity, ATP content and acid phosphoesterase activityduring seed development of turf-type tall fescue, the seed vigor of tall fescue were studied. Combining withseed moisture content and yield, the optimal harvesting time of tall fescue was determined. The results indica-ted that the seed vigor increased continuously along with seed maturity, and the higher seed vigor was achievedat 19th day after perk anthesis and maintained continuously until 31st day after peak anthesis. At 25th day af-ter peak anthesis, the highest yield of 3 533 kg ha-1 and the good quality of seeds of tall fescue were harvestedwith 32.19% moisture content. From 22nd to 31st day after peak anthesis, the seed yield of 3 300 kg ha-1 andthe good quality seeds of tall fescue were harvested with 40 -12.43% moisture content, and the span was theoptimal harvesting time.关键词
