Seed germination of Ipomoea pes-caprae (L.) Sweet
摘要
Abstract
In this research the influence of different treatments on seed germination characteristics of Ipomoea pes-caprae were studied to determine effective measures for enhancing the germination rate and germination potential. Treatments included a mechanical treatment, 98％ H2SO4 solution for 90 min, 40％ NaOH solution for 36 h, and a temperature treatment between 15 - 20, 20 - 25 and 25 - 30 ℃. Results showed that the mechanical treatment was best with both the average germination potential and average germination rate of 95.3％. Also, with the H2O4 solution, the average germination potential was 91.2％, and the average germination rate was 93.5％. The NaOH solution treatment improved the average germination potential to 79.4％ and the average germination rate to 40％. For the temperature treatment, germination was highest when temperatures were between 25 - 30 ℃ with the average germination potential reaching 24.6％ and the average germination rate attaining 43.4％. Thus, the mechanical, the 98％ H2SO4, or the NaOH solution treatments could improve seed germination of I. pes-caprae.关键词
