Abstract: 以体细胞杂种红橘+枳和红橘+粗柠檬、有性杂种Troyer枳橙和Swingle枳柚、枳(对照)作砧木的‘国庆4号'温州蜜柑幼树为试材,通过盆栽试验研究了砧木对幼树的影响.结果表明:两类杂种砧木处理的生长势强于对照;不同种类的砧木对叶片各种矿质营养含量具有明显的影响;4种处理叶片光合色素含量和叶绿素a/b高于对照或与其差异不显著;两种体细胞杂种砧木处理的碳水化合物含量高于对照或与其差异不显著,而两种有性杂种砧木处理的碳水化合物含量低于对照或与其差异不显著;对照的叶片在POD活性上高于处理,两种体细胞杂种砧木处理在叶片POD活性上介于两种有性杂种砧木处理之间;两年里叶片POD活性分别与当年树冠体积极显著负相关.
