摘　　要：以5年生酿酒葡萄’北玫’为试材,在休眠期对枝蔓喷施氯苯胺灵和马来酰肼,研究其对葡萄春季萌芽及新梢抗冻性的影响。结果表明:马来酰肼和氯苯胺灵处理均可推迟葡萄的物候期1~4 d,降低了萌芽率和新梢长度,增加了新梢粗度;使萌芽后新梢中可溶性糖、脯氨酸含量提高,降低了相对电导率和丙二醛含量,明显降低晚霜冻期间新梢受冻率。其中3 g·L-1氯苯胺灵和5 g·L-1马来酰肼处理显著降低新梢相对电导率和丙二醛含量,提高了脯氨酸和可溶性糖含量,葡萄枝蔓受冻率也显著降低。因此,在休眠期对不埋土的酿酒葡萄’北玫’枝蔓喷施适宜浓度的氯苯胺灵或马来酰肼,可以通过延迟萌芽,提高新梢抗性来提高对晚霜冻的抗冻性,降低晚霜冻危害。Taking 5-year-old ’Beimei’ grapevine as experimental material,the effect of branch sprayed chlorphopham and maleic hydrazide in dormancy period on grape germination and the resistance to spring frost of new shoot were studied.The results showed that the phenological period with maleic hydrazide and chlorphopham treatment were delayed 1-4 days,the germination rate and shoot length were reduced,and increased the length of shoots.The sugar and proline content in shoots were increased,and the relative conductivity and malondialdehyde content were decreased,and freezing rate was decreased in the end.Treatment with 3 g·L-1 chlorphopham and 10 g·L-1 maleic hydrazide could significantly reduced the rate of freezing to the shoots,and the relative conductivity and malondialdehyde content of the shoots.At the same time,the soluble sugar and proline content were significantly increased.So branch spayed appropriate concentrations of maleic hydrazide and chlorphopham in dormancy period could delayed phenology stage,increase the content of proline and soluble sugar,reduce the membrane permeability and malondialdehyde content,in the end,the resistance of spring frost was increased.
