单氰胺对桂南地区巨峰葡萄催芽效果研究

The cyanamide effects on germination of Kyoho Grape in Southern Guangxi

以平棚架式栽培的6年生巨峰葡萄为试材,用稀释的单氰胺海棉球点药与喷施枝条2种方式催芽。结果表明,不同催芽时间、单氰胺浓度及催芽方式,均能显著的影响巨峰葡萄的萌芽率,稀释25倍的单氰胺浓度催芽效果较好,海棉球点药效果优于喷施枝条。此外,不同浓度的单氰胺处理对葡萄的花芽分化也有较为显著的影响。

In order to investigate the effect of different germination time and way, as well as different cyanamide concentration on the Kyoho grape branches spring bud, 6 years old of Kyoho grape as materials, cultivated under level scaffolding. From February 2011, 10-16, daily diluted with cyanamide 15-fold germinated every day. On February 10,used 6 different cyanamide concentration, including of 10-fold, 15-fold, 20-fold, 30-fold, 40-fold and 50-fold. Cotton ball point and spraying the branches of two ways were germinated, analyzed the germination rate and the flower situation. The results showed that： different germination time, the concentration of cyanamide and germination way can significantly affect germination rate of Kyoho grape, diluted 25-fold germination effected of cyanamide better than the others, cotton ball point was more effective than spraying the branches. Different concen- trations of cyanamide was treated grape bud which had more significant impact.
