猕猴桃的冬季耐寒性,意大利北部一次冬季冻害后的调查《New Zealand Journal of Experimental Agriculture(1987) 15(4) 》在1985年元月一次严重的冬寒(气温降至-23℃)后,对意大利北部的25个果园的猕猴桃(Actinidia deliciasa var deliciosa)的开花量进行了调查以评估其抗寒性。其中海欧特(Hayward)雌株的结果枝比例在-11℃开始降低;大约在-18℃时次年春天结果枝很少抽生。随着气温的降低,从冬芽基轴分生组织分化的营养枝的比例增加。马塔瓦(Matua)的
Winter Cold Hardiness in Kiwi, A Survey of Winter Frost Harm in Northern Italy After a severe winter cold (temperature dropped to -23 ° C) in January 1985, the New Zealand Journal of Experimental Agriculture (1987) 15 (4) Flowering of Actinidia deliciasa var deliciosa in 25 orchards in northern Italy was investigated to assess its cold resistance. Among them, the proportion of fruiting branches in Hayward began to decrease at -11 ° C; in the following spring, fruiting branches rarely sewed at about -18 ° C. With the decrease of temperature, the proportion of vegetative shoots differentiated from the winter bud base axis meristem increased. Matua
