It has been reported that soaking sweet orange seeds with 1000ppm gibberellin for 24 hours can accelerate the germination speed of seeds, increase the germination rate, make the emergence uniform, and promote the growth of seedlings; dip the Maltese ordinary sweet orange seeds with 200ppm gibberellin solution 12 In the hour, the germination effect was the best; at 3 to 4 °C, the volcanic orange seeds harvested in April were treated with gibberellin for 3 weeks, and the germination rate was almost 100%. In this experiment, the fruit of the loquat was collected in Chongqing on August 2, 1986, the young seeds were peeled off, the colloid was washed and the inner and outer seed coats were peeled off, and soaked for 24 hours in gibberellin and cytokinin solutions at different temperatures. , placed in a 26 ~ 28 ° C incubator in the germination. The results showed that the treatment of gibberellin or cytokinin 1000ppm alone significantly promoted the germination of the bristles, which was the preferred treatment concentration compared with 500 and 1500 ppm; and the combination of gibberellin and cytokinin (1000 ppm each). The shortcomings of gibberellin treatment of roots, stems and slender slenderness and cytokinin treatment of roots and stems were overcome. The root and stem length and seed germination rate of seedlings were higher than that of the control.
