摘要
以树番茄干种子为试材,分别用15、30、45、60、75℃的温水浸种至自然冷却,然后每隔8h换一次水,共浸泡处理48h,测定树番茄种子的各项发芽指标,研究了不同水温浸种对树番茄种子发芽的影响,以期为树番茄种子繁殖提供参考依据。结果表明:树番茄种子的最适浸种温度为45℃,在此处理下的腐烂率为4.00%,异状发芽率为0.67%,发芽率为64.00%,发芽指数为2.43,活力指数为5.24。
The dry seed of Cyphomandra betacea Sendtn.was used as the test material.The method of soaking seeds with warm water which the seeds of Cyphomandra betacea Sendtn.were soaking at15 ℃,30 ℃,45 ℃,60 ℃,75 ℃for natural cooling,and soaked for 48 hours by changing water every8 hours was used to determine the seed germination index.The effects of soaking seeds at different water temperatures on the germination of Cyphomandra betacea Sendtn.seeds were studied in order to provide theoretical and practical basis for the propagation of Cyphomandra betacea Sendtn.seeds.The results showed that the optimum temperature for soaking tomato seeds was 45℃,the rotting rate of 4.00%,and abnormal germination rate was 0.67%,the germination rate of 64.00%,germination index was 2.43,and vigor index was 5.24 in 45 ℃.
