摘要
以蕹菜（ＩｐｏｍｏｅａａｑｕａｔｉｃａＦｏｒｓｋ．）小叶品种带芽节段为繁殖体，用４％海藻酸钠（加入ＭＳ基本培养基及３％蔗糖）和２％氯化钙包裹制作人工种子。结果表明，较佳繁殖体的腋芽长度为０．５～３ｍｍ的带芽节段；人工种子在ＭＳ琼脂培养基上的萌发率达引．０２％，在营养土中的成苗率为２７．５９％，幼苗移栽成活率１００％；低温（４±１℃）贮藏３０、６０和９０天后，萌发率分别为４２％、２６％和１８％。
The nodes with axillary buds from Ipomoea aquatica Forsk. were encapsulated with 4% sodium alginate (basal MS medium with 3% sucrose) and 2% calcium chloride as artificial seeds. The better propagators were the nodes with 0.5-3mm long axillary buds. The germination frequency of artificial seeds reached 51.02% on MS agar medium and their seedling frequency reach 27.59% in humus soil. The seedlings were all well established when they were planted in the field. The germination frequency of artificial seeds were 42%,26% and 18% respectively after storage at lower temperature (4 ±1℃ ) for 30, 60 and 90 days.
