1985年5月6、10、20、24日,在本所伏令夏橙园用细胞激动素(BA)和赤霉素(GA)防止伏令夏橙生理落果,收到良好效果。BA对生理落果前期(细胞分裂期)有明显效果,而对生理落果后期(细胞膨大期)无效。如用BA300ppm处理3次,第二次落果高峰(细胞分裂期)着果86％,第三次落果高峰(细胞膨大期)着果28％;BA300ppm处理,次,第二次落果高峰着果68％,第三次落果高峰着果25％;BA500ppm
On May 6, 1985, May 20, and January 24, cytokinin (BA) and gibberellic acid (GA) were used to prevent the physiological decolonization of Valsum Indosinx in summer orange garden in Vorgenzen, and good results were obtained. BA had a significant effect on the early stage of physiological decapitation (cell division), but not on the late stage of physiological decapitation (cell expansion). If treated with BA300ppm three times, the second fruit drop peak (cell division) fruit 86%, the third fruit drop peak (cell enlargement phase) fruit 28%; BA300ppm treatment, times, the second fruit drop peak 68 %, The third drop fruit peak fruit 25%; BA500ppm
