为了使甜瓜雄性不育系种子在低温下萌发长苗,将其种子用盐溶液预处理。最佳的方法是用2.5%KNO_3在黑暗中处理16小时。大田研究表明,引发可使甜瓜雄性不育系种子在较低温下萌发生长,这是提高甜瓜杂交制种的有效方法。
In order to germinate the long seedlings of melon male sterile lines at low temperature, their seeds were pretreated with salt solution. The best method is to treat with 2.5% KNO 3 in the dark for 16 hours. Daejeon studies have shown that priming can induce germination and growth of melon male sterile lines at lower temperature, which is an effective way to improve the hybrid seed production of melon.
