“玫瑰香”(Muscat Hamburg)是我国葡萄生产上广泛栽培的优良生食品种。北京农业大学果树教研组在各生产教学基点进行四年试验(1959—1962)的结果表明,赤霉素对有核品种如玫瑰香葡萄亦具有显著的效应。 花前花期处理的效应 在开花前两周以内用2.5—500ppm范围内的浓度处理花序,强烈刺激穗轴花柄伸长,提前开花期2—3天。同时花序黄化、扭曲,大量的子房不能发育而僵化在各级穗轴上,造成严重的落花落果
Muscat Hamburg is a fine variety of raw food widely grown in our country’s grapes. The results of the four-year trial (1959-1962) conducted by the fruit tree teaching and research group at Beijing Agricultural University on the production of teaching bases indicated that gibberellin also had a significant effect on the nuclear varieties such as Muscat grape. Effect of pre-flowering treatment The inflorescences were treated within 2.5-500 ppm within two weeks prior to flowering, strongly stimulating the elongation of the stems of the spinach and premature flowering for 2-3 days. At the same time inflorescence yellow, twisted, a large number of ovary can not develop and rigid at all levels of the cob, causing serious drop
