【摘要】 从蜂腊及蚕粪中提取高纯度的三十烷醇,是一种新的植物生长刺激剂,能促进水稻秧苗、白菜、黄瓜及马铃薯芽体组织培养的植株生长,增加鲜重及干物重。同时,促进水稻秧苗及黄瓜幼苗对氮、磷肥料的吸收。用³²P-同位素示踪表明,积累在黄瓜苗根部的放射性强度较对照区增加12.36—16.19％。 在盆栽条件下以淋灌10ppm三十烷醇稀释液的效果较好,马铃薯芽体组织培养基中含2ppm为佳。更多还原

【Abstract】 Highly pure 1-triacontanol was extracted from bee wax and silkworm feces. Although it contained a little octocosanol but it did not show inhibitory effect on the growth of plants.By irrigation of 10 ppm solution of triacontanol to seedings of rice and several kinds of vegetables such as pak choi, cucumber and potatoplanted in soil,the regulator was found to stimulate plant growth and to increase their fresh weight and dry weight.The growth response-of rice and cucumber seedings to triacontanol was characterized by an increase in nitrogen and phosphorus contend. When treated with triacontanol the cucumiber seedings absorbed more 32P than did ,the control,and more 32 P was distributed in roots of the treated seedings.Addition of 1-3 ppm of triacontauol in the MS medium of tissue culture of potato buds stimulated the early growth of the buds and roots with an increase in root number and length.更多还原
