Abstract
本試驗係以硬化處理及滲調處理技術進行探討屏東尖葉青骨與白骨大葉兩不同蕹菜品種種子活力之改進情形，初步結果發現以種子浸水四小時後乾燥二次循環乾濕處理（硬化處理），可以提早種子之發芽並促使發芽快速整齊，在滲調處理方面，不同濃度 PEG 6000溶液於不同溫度條件下進行不同期間之浸潤處理，初步結果發現種子在-1.0 M Pa PEG 溶液在30°C浸潤處理1天，效果較佳，不但提早蕹菜種子發芽，促使種子發芽快速整齊並增加發芽百分比。
The present study was emphasized on improvemet of seed quality of water convolvulus, cultivars Pingtung Green Stem (pointed leaf) and white Stem (broad leaf) by means of hardening (hydration and dehydration) and osmotic seed treament in fiscal year of 1991. The results indicated that the germination of water convolvulus seeds can be promoted and synchronized by 2 cycles of hydration and dehydration seed treatment with 4 hours of seed soaking. The water convolvulus seed were also primed with the concentration of PEG 6000 solution of -0.5, -1.0 and -1.5 Mpa at the temperature of 20, 25, 30, and 35°C for 1 and 2 days. The results indicated that optimum condition for priming of water convolvulus seeds was the seeds incubated by -1.0 MPa PEG 6000 solution at 30°C for 24 hours. All the primed seeds showed earlier and synchronous in germination and advanced the percentage of seed germination.
