摘要
研究了不同嫁接方式对黄瓜嫁接苗成活率、生物学性状及其植株抗病性的影响.结果表明:以湘园三号黄瓜作为接穗,黑籽南瓜作为砧木,采用靠接、顶插、劈切、芽接四种嫁接方式,其嫁接苗成活率分别为100.0%、78.4%、92.9%和75.5%;其平均株高、平均真叶数均以靠接苗为大,分别为15.8cm、3.0片;四种嫁接苗的平均株幅无明显差异.以津春二号黄瓜作为接穗,分别以黑籽南瓜和西葫芦作为砧木,均采用靠接方式,其靠接苗成活率分别为99.4%、100.0%,平均株高、平均株幅和真叶数均以前者为大.经嫁接后,黄瓜植株枯萎病发病率明显下降,控制在0～14.0%范围之内;而未经嫁接的津春二号(对照1)、津春三号(对照2)黄瓜植株,病株率分别达到48.0%、36.0%.
In this paper, influences of different grafting pattems on surviving rates and biological properties of cucumber seedlings were studied. The results showed that surviving rates of 4 kinds of different grafting seedlings were 100.0 %, 78.4 %, 92.9 % and 75.5 % respectively, average plant height and average real leaves numbe13 of near - grafting cucunmber seedlings were the largest and no apparent difference existed in terms of average plant width under 4 kinds of different grafting pattems including neargrafting, insert - grafting, split - grafting and bud - grafting on the basis of scicon - “Xiangyuan NO. 3”cucumber and stock - “black seed pumpkin”. The surviving rates of near - grafting seedlings are 99.4 %, 100.0 % respectively. Average plant height, average plant width and average real leaves numbets of former were larger than latter. After being grafted, withering disease rate of cucumber plants de- scented apparently（0 - 14.0 % ）, but those of “Jinchun No. 2” （ckl） and “Jinchun No. 3” （ck2） cucumber plants which were not grafted amounted to 48.0 % ,36.0 % respectively.
