为提高沙田柚着果率,1989年我们在遂宁市市中区棉花原种场进行了赤霉素保果试验。试材为5年生幼树,于第一次生理落果结束后的5月24日用200ppm赤霉素液涂幼果533个(12株)。6月中旬即发现畸形果实。7月17日统计,着果192个,着果率为36.0％;畸形果88个,占着果总数的45.9％。畸形果主要表现果个偏小,果实扭曲,果皮厚度不均,
In order to improve the fruit yield of Shatian pomelo, in 1989 we conducted the gibberellic acid conservation test in the cotton original seed market in Suining City Central District. The test material was 5-year-old saplings, and 533 young fruits (12 plants) were coated with 200ppm gibberellin solution on May 24 after the first physiological drop-off. In mid-June that deformities found fruit. July 17 statistics, fruit 192, the fruit rate of 36.0%; 88 deformed fruit, accounting for 45.9% of the total number of fruit. The main fruit deformity fruit is a small fruit, fruit distortion, peel thickness uneven,
