中文摘要:
      以石硖龙眼为接穗,研究不同砧木对石硖龙眼生长及叶片矿质元素含量的影响。结果表明,不 同砧木对石硖龙眼的生长量有明显的影响,以沙梨木、顶圆和赐合种为砧木的龙眼生长势较旺盛,以公妈 本、蜀冠、后巷本、乌龙岭、新滘乌圆为砧木的龙眼生长量较小。不同砧木对石硖龙眼叶片矿质元素含量有 不同的影响,以沙梨木作砧木的龙眼叶片Ca、Mg 含量较高,以东壁、新滘乌圆作砧木的龙眼叶片Fe、Mn、 Cu 含量较高,以赐合种作砧木的龙眼叶片Zn、B 含量较高,以顶圆作砧木的龙眼叶片P 含量较高,说明砧 木对植株叶片主要矿质营养的代谢有显著影响。利用逐步回归方法,初步建立了石硖嫁接苗生长量评估预 测模型。
英文摘要:
      In this study,we reseached the influences of different rootstocks on growth and contents of mineral elements in leaf of “ Shixia” longan. The results showed that the growth of ‘ Shixia’ longan was significantly affected by rootstock. The longan plants with‘ Shalimu’,‘Dingyuan’ and‘ Cihezhong’ cultivar as rootstock had larger growth than the longan plant with‘ Gongmaben’,‘Shuguan’,‘Houxiangben’,‘Wulongling’, ‘Xinjiaowuyuan’ as rootstock. We also found that the mineral elements contents in‘ Shixai’ longan leaf were affected by different rootstocks. The Ca,Mg contents in leaf with‘ Shalimu’as rootstock was higher than another cultivars as rootstock;The Fe,Mn,Cu contents in leaf with‘ Dongbi’ and‘ Xinjiaowuyuan’ as rootstock was higher than another cultivars as rootstock;The Zn,B contents in leaf with‘Cihezhong’as rootstock was higher than another cultivars as rootstock;The P content in leaf with‘ Dingyuan’as rootstock was higher than another cultivars as rootstock. The results indicated that rootstock obviously affected the main mineral elements metabolism. The ‘Shixia’ longan growth evaluation model was established using stepwise regression method.
