摘要
研究了 5个柑桔细胞杂种的抗寒性 ,其结果是伏令夏橙 +宜昌橙 (C .sinensisOsb .cv .Valencia +C .ichangensisSwingle)抗 - 11℃、伏令夏橙 +‘key’来檬 (C .sinensisOsb .cv .Valencia +C .aurantifoliacv .Keylime)抗- 7 5 9℃、伏令夏橙 +宁波金柑 (C .sinensisOsb .cv .Valencia +FortunellacrassifoliaSwinglecv .Meiwa)抗 - 9 5 4℃、哈姆林甜橙 +粗柠檬 (C .sinensisOsb .cv .Hamlin +C .jamhiriL .)抗 - 7 1℃ ,哈姆林甜橙 +飞龙枳 (CitrussinensisOsb .cv .Hamlin +PoncirustrifoliataRaf.cv .FlyingDragon)抗 - 12 89℃、并且证明了 5个体细胞杂种的抗寒性均介于两亲本之间。其中哈姆林甜橙 +飞龙枳杂种、伏令夏橙 +宜昌橙杂种的抗寒性均高于其它几个组合。
Freezing resistance of 5 Citrus somatic hybrids were studied.The results showed that the freezing resistunce of Valencia sweet orange ( C.sinensis Osb.cv.Valencia)+Ichang papeda ( C.ichangensis Swingle) was -11℃,Valencia sweet orange+ ‘Key’ lime ( C.aurantifolia Key lime) was -7 59℃,Valencia sweet orange+ Meiwa Kumquat ( Fortunella Crassifolia Swingle cv.Meiwa) was -9 54℃,Hamlin sweet orange ( Citrus sinensis Osb.cv.Hamlin)+ Rough lemon ( C.jamhiri L.) was -7 1℃,Hamlin sweet orange + Flying Dragon trifoliate orange ( Pocirus trifoliata Raf.cv.Flying Dragon) was -12 89℃.And it was proved that freezing resistance of 5 citrus somatic hybrids was all between parents.Among them Hamlin sweet orange+Flying Dragon trifoliate orange and Valencia sweet orange+Ichang papeda had higher resistance to low temperatures than others.The test was also proved that freezing resistance of citrus somatic hybrids was hardly influenced by cultivation managements.
