บทคัดย่อ

Shoot growth of the Fuji apple cultivar was retarded by spraying with paclobutrazol at 500 ppm, four times during the growing season, Significant difference in the number of flower buds between the treated and the untreated trees were found. Carbohydrate and nitrogen levels in the treated trees was higher than in the untreated ones. Both calcium and hydrogen cyanamide enhanced bud break but hydrogen cyanamide was more effective. Addition of “Merit” ( 7-5-3 ( NPK ) formula fertilizer ) to these chemicals increased induction of bud break under simulated tropical / sub – tropical conditions. Results varied with application time and these results are not fully understood and required further investigation.
