摘要
以４个柑桔体细胞杂种哈姆林甜橙＋飞龙炽（ＣｉｔｒｕｓｓｉｎｅｎｓｉｓＯｓｂ．ｃｖ．Ｈａｍｌｉｎ＋ＰｏｎｃｉｒｕｓｔｒｉｆｏｌｉａｔａＲａｆ．ｃｖ．ＦｌｙｉｎｇＤｒａｇｏｎ）、哈姆林甜橙＋粗柠檬（Ｃ．ｓｉｎｅｎｓｉｓＯｓｂ．ｃｖ．Ｈａｍｌｉｎ＋Ｃ．ｊａｍｈｉｒｉＬ．）、伏今夏橙＋宁波金柑（Ｃ．ｓｉｎｅｎｓｉｓ，Ｏｓｂ．ｃｖ．Ｖａｌｅｎｃｉａ十ＦｏｒｔｕｎｅｌｌａｃｒａｓｓｉｆｏｌｉａＳｗｉｎｇｌｅｃｖ．Ｍｅｉｗａ）、伏令夏橙＋宜昌橙（Ｃ．ｓｉｎｅｎｓｉｓＯｓｂ．ｃｖ．Ｖａｌｅｎｃｉａ＋Ｃ．ｉｃｈａｎｇｅｎｓｉｓＳｗｉｎｇｌｅ）及其融合亲本为试材，对其抗寒性、耐热性和抗脚腐病性能进行了研究，并从叶片膜脂脂肪酸成分分析了体细胞杂种的抗寒性和耐热性。研究结果表明，哈姆林甜橙＋飞龙枳杂种表现抗脚腐病、抗寒（－１４℃）、耐热（５２℃）、矮化、半落叶、扦插易生根，是极有希望的新砧木类型；伏令夏橙＋宜昌橙杂种表现抗寒（－１２℃）；哈姆林甜橙＋粗柠檬杂种表现耐热（５３℃）。４个体细胞杂种的抗性较之抗性弱的亲本一方都有提高。
The resistance to the cold, heat and Phytophthora of 4 Citrus somatic hybrids, Hamlin sweet orange (Citrus sinensis Osb. cv. Hamlin) +Flying Dragon trifoliate orange (Pocirus trifoliata Raf. cv. Flying Dragon),Hamlin sweet orange+Rough lemon (C. jambhiri L.), Valencia sweet orange (C. sinensis Osb. cv. Valencia) +Meiwa Kumquat (Fortunella crasslfolia Swingle cv. Meiwa) and' Valencia' sweet orange+Ichang papeda (C. ichangensis Swingle), and their fused parents were studied. The somatic hybrid Hamlin sweet orange+Flying Dragon trifoliate orange showed higher assistance to Phytophthora, coldness (-14℃) and heat (52℃), dwarfing, half-deciduous, easy rooting by stem cutting. Valencia sweet orallge+Ichang papeds showed resistance to coldness (-12℃). Hamlin sweet orange+Rough lemon showed the resistance to heat (53℃) They may be used for Citrus rootstock improvement.
