【摘要】 研究了观赏枣嫁接繁殖中,不同砧穗比对3个不同枝型观赏枣萌芽及生长的影响。结果表明:嫁接中各品种保持砧穗比>1对提高嫁接萌芽率有正面影响;3个品种粗度小的接穗萌芽期总体上早于粗度大的接穗,但随着嫁接后时间的推移,不同粗度接穗的萌芽率趋于接近;各品种植株的生长状况主要与品种自身生物学特性及砧木的粗度有关,砧木粗度大,苗木生长强,而且强弱苗之间的差距在不断加大。更多还原

【Abstract】 The objective of the study was to investigate the effects of different rootstock-scion ratios in grafting and reproduction on the sprouting and growth of three different shoot-type ornamental Chinese jujube trees.The results showed that when rootstock-scion ratio in grafting was beyond 1,it had a positive effect to raise germination rate.The germination time of the scion with smaller width of Longzao and Dalilongzao was earlier than those scions with greater width.However,with the increase of grafting time,the germination rate of different widths scions showed rough similarity.The shoot growth of each variety was related with its own biological characteristics and the width of rootstock.Bigger width rootstock would grow stronger grafted seedling.The difference between the strong and the weak seedlings was getting bigger and bigger due to the width differences.更多还原
