摘要: 抗寒育种是核桃品种选育中的一个重要问题。本文对引自意大利罗马果树研究所的15个核桃品种中的29个品系的研究显示:品种间的单叶重差异较大,最重者是Franquette和Serrento。对叶片细胞结构紧密度(CTR)观察表明:品种间存在极显著差异。最高者为Corne品种的三个品系,它们的CTR>50%;Franquette则居中(CTR=40%~50%);Franquette则居中(CTR=40%~50%);而Teharma为最低(CTR<40%)。叶片细胞膜透性(CMP)观察表明:抗寒性较强的品种中,CMP值差别较小;反之,则较大。数年的观察发现:细胞膜透性与品种抗寒性呈显著正相关,而细胞结构紧密度则与品种抗寒性呈显著负相关。这两项指标可以作为核桃品种抗寒性鉴定的预选指标。

Abstract: Selecting the cold-resistence plants is an important problem in the breeding of walnut. The result of a study of about 29 strains of 15 varieties of walnut that were introduced from Roma Fruit Institute of Italy showed: the weight of one single leaf was different among varieties, the highest weight varieties were Franquette and Serrento. There was a significant difference in the CTR among the different varieties’ leaves: the highest were the 3 trains of Corne, their CTR> 50%; that of strains of the Franquette were of medium (CTR=40%~50%) and the Teharma were the lowermost (CTR<40%). The varience of the cell membrane permeability (CMP) changes less inter the varieties which had a forciable cold-resistence than that the feeble cold-resistence varieties. These two terms may be taken as two pre-selecting indications for the identification of variety on cold-resistence of walnut strains.
