| 摘 要： | 目的]探讨脱毒甘薯生长发育特性和增产效果,选育出适合当地农业生产的脱毒甘薯。方法]以"一窝红"和"卢选1号"2个甘薯品种为研究材料,对其整个生育过程进行调查,对各关键时期植株生长发育的形态指标进行了测定和研究。结果]脱毒在很大程度上影响了甘薯植株的生长发育,一些形态及产量指标如蔓长,茎、叶鲜重,块根直径,块根重量,茎分支数,结薯数和单株产量都发生显著变化。生育前期脱毒甘薯植株的生长优势表现在地上部,后期优势表现在以产量形成为主的地下根部。结论]脱毒甘薯的增产效果明显,因此应用脱毒苗是当前解决病毒病的最好方法。

| Abstract: | Objective] To discuss the growth and development characteristics and yield increasing effects of Ipomoea batatas (L.) Lam.after detoxification,and to breed virus-free I.batatas suitable for local agricultural production.Method] With Yiwohong and Luxuan 2 as the research materials,the whole growth period was investigated,and the morphological index of plant development and growth at key periods were detected.Result] Detoxification greatly affected the growth and development of I.batatas.Some morphological and yield indicators changed significantly,such as vine length,stem and leaf fresh weight,tuber diameter,tuber weight,stem branches number,tuberization number and yield per plant.The aboveground part of virus-free I.batatas showed growth advantage during early stage of growth;while the underground root part showed growth advantage in late stage.Conclusion] The yield of virus-free I.batatas enhanced significantly.Thus,applying virus-free seedlings was the best method at present. |
