摘  要:
对引种的北美栎树进行的扦插与嫁接繁殖试验结果表明:柳叶栎、纳塔栎和水栎1年生实生母树上的穗条,具有一定的扦插繁殖潜力。以200×10-6ABT6号处理纳塔栎插穗,生根率达52%;以100×10-6ABT6号处理水栎插穗,生根率达22.0%,以100×10-6ABT6号处理柳叶栎插穗,生根率达70%。但从6年生柳叶栎母树上采穗,并进行相同处理扦插后则不能生根,愈合率仅为7.2%。上述3种栎树的扦插生根能力顺序依次为柳叶栎>纳塔栎>水栎;全光喷雾设施的生根效果优于封闭式扦插。生根剂ABT6号处理优于NAA处理和NAA+VB2处理。以麻栎为砧木,对纳塔栎、红栎和水栎等进行春季枝接后,60 d后的成活率分别为47.5%~61.2%,47.5%和13.3%~15.0%,且春季枝接的效果优于秋季芽接。

摘  要:
The cut rooting rate from Quercus phellos,Q.nuttalli,and Q.nigra branch tips of 1-year-old sapling were 70%,52.0% and 22.0% respectively by the best ABT6 treatment,but no rooting from Q.phellos branch of 6-year-old sapling.The rooting ability of Q.phellos was better than that of Q.nuttallii and Q.nigra.Availability of facility was auto-interval spray,better than general closing in cutting with plastic film.Rooting rate of ABT6 treating was better than that with NAA +VB2 and NAA treatments.The field grafting survivals of Q.nuttallii,Q.nigra and Q.coccinea were 47.5%~61.2%,47.5% and 13.3%~15.0% respectively with the rootstock of Q.acutissima after 2 months,but the survivals declined in the end of one season.The bench grafting result in spring was better than budding in autumn.
