软枣猕猴桃(Actinidia arguta(Sieb.et Zucc.)Planch.ex Miq.),属猕猴桃科(Actinidiaceae),猕猴桃属(Actinidia),落叶大藤本,具有很高的营养价值和药用价值.主要采用种子及扦插方式进行种苗繁殖.但种子繁殖周期长、苗木生长势参差不齐;枝条扦插受母株数量及质量限制,繁殖系数较低,减慢了优异资源的驯化及推广工作.植物组织培养具有生长周期短、繁殖系数高等优点,应用此技术可加快软枣猕猴桃优异资源的驯化及种苗繁殖速度.本文是以延边大学农学院朴一龙教授提供的20-03软枣猕猴桃雄性株进行组织培养获得的试验结果技术总结. 相似文献

In order to study the variation of Begonia × hiemalis after in vitro propagation, one plant of ‘Aphrodite Pink’ and one of ‘Schwabenland Red’ were vegetatively propagated in four ways. One group of plants was obtained by propagation by means of cuttings. For the second group, the bacterial elimination system, as developed by Hakkaart and Versluijs (1983), was applied which includes an in vitro propagation step. The third and fourth groups were obtained by adding one and two cycles, respectively, of in vitro propagation after the bacterial elimination, so that one, two and three propagation cycles could be compared. One cycle, followed by bacterial elimination, gave nearly uniform offspring. However, when this was followed by one or two cycles of in vitro propagation, the variation increased. Variation also increased when the size of the plantlets obtained in vitro decreased. Thus, an important source of variation can be avoided by eliminating the smallest in vitro plantlets. It is recommended to flower and select the plants before propagation by conventional cuttings, whether or not a further in vitro propagation is applied after the bacterial elimination. 相似文献

对黄茉莉的育苗技术与矮化盆栽技术进行了研究。结果表明:黄茉莉能够用压条繁殖及穴盘扦插繁殖育苗。压条繁殖成活率高,但繁殖系数小;而穴盘扦插育苗的繁殖系数大,根系发达,苗木健壮,成苗整齐,最好的育苗时期在4、5月。采用一年3次修剪的方法,能够很好地解决藤本黄茉莉盆栽矮化的问题。 相似文献
