通过抗枯死能力不同黑穗醋栗（ＲｉｂｅｓｎｉｇｒｎｍＬ．）品种的形态及解剖观察，含水量测定，人工冷冻试验和冻害观察等研究，结果表明，黑穗醋栗枝条含水量下降到３３％以下时出现死亡现象．下降到２４％以下时会大量死亡．死亡时期集中在４月上旬至中旬，而不是最冷的月份．冻害是造成株丛枯死的主要原因，冻害部位发生在枝条基部距地表之上５～２０ｃｍ范围内，由冬季到春季冻害逐渐发展和加重，因此冻害引起的枯死是自下而上的，是严重的．生理干旱也能引起枯死，但它是自上而下的。为害较轻．冻害和生理干旱经常同时发生，此时株丛死亡更重．由于不同品种抗冻能力和抗脱水能力的差异，存在着越冬枯死程度的差异．
Morphological and anatomical observation, water content determination, artificial freezing test and freezing damage observation of different varieties of black currant (RibesnigrnmL.) Were carried out through anti-blight ability. The results showed that when the water content of black currant branches dropped below 33% Death phenomenon. When it drops below 24%, it will die in large numbers. The period of death is concentrated in the first ten days of mid-April, not the coldest month. Frost damage is the main reason that caused the blight to die. Frost damage occurred in the range of 5 ~ 20cm above the ground at the base of branches. Frost damage gradually increased and intensified from winter to spring, so the frostbite caused by frostbite was bottom-up and serious of. Physiological drought can also cause death, but it is top-down. Less harmful. Frost damage and physiological drought often occur at the same time. Due to the different varieties of anti-freezing ability and anti-dehydration ability differences, there is the difference between the degree of winter dead.
