摘要: 以体细胞杂种红橘+枳、红橘+粗柠檬和Troyer枳橙、Swingle枳柚、枳(对照)作砧木的
‘国庆4号’温州蜜柑2年生嫁接苗为试材,通过盆栽试验研究了砧木对苗木生长和抗氧化酶类活性的影响。结果表明:4种处理生长势均比对照旺盛;以红橘+枳作砧木处理花量极显著地高于对照,其余3种砧木则低于对照;还讨论了两种体细胞杂种砧木的利用价值。砧木不影响接穗叶片可溶性蛋白含量和过氧化氢酶(CAT)活性的年变化特征,明显影响叶片超氧化物歧化酶(SOD)和过氧化物酶(POD)活性年动态变化特征,在各时期不同砧木对接穗叶片生化指标有明显影响(4月SOD活性除外);在各对应时期,接穗叶片POD活性高低与新梢生长量和树冠体积大小负相关;在12月,不同砧木根系生化指标差异明显,且根系与接穗叶片在SOD和POD活性上正相关。

Abstract: It was conducted with ‘Guoqing 4’Satsuma mandarin two-year.old young tree whose rootstocks were Trifoliate(CK),Troyer Citrange,Swingle Citrumelo,and Red tangerine+Trifoliate,Red tange-rine +Rough lemon somatic hybrids.Studies on the effects of rootstocks on the growth and the activities of antioxidant enzymes through potted experiment.The results are the following.The four kinds of treatments grew more vigorously than CK.The number of blossoms of Red tangerine+Trifoliate was higher than CK.and the other three were to the contrary.Rootstocks did not influence the annual changes in the content of soluble pro.tein and the activity of CAT.They bviously influence the annual changes in the activities of SOD and POD.In different periods,rootstocks notably influenced the biochemical indexes(except for SOD in leaf in April).During the corresponding periods,the POD activities were negatively correlated with the shoot growth and the canopy volume.In December,there existed significant difference in the biochemical indexes among various rootstocks.The POD and the SOD activities in roots were respectively positively corelated with that in leaves.The utilization potential of these two somatic hybrids were discussed.
