本文报道了几种植物生长刺激素、微量元素和氮磷等营养盐对细基江蓠(Gracilaria tenu-istipitata)孢子萌发影响的试验情况。结果表明:(1)低浓度乙烯利(10ppm左右)对细基江蓠孢子萌发有积极的作用;(2)β-吲哚乙酸(40ppm)和增产素(1ppm 以下)对细基江蓠孢子的萌发有促进作用;(3)细基江蓠在孢子萌发阶段施用氮肥和磷肥有积极效果。此外,还探讨了两种微量元素——钼和锰分别对细基江蓠孢子萌发的影响。 在进行江蓠采孢子培苗时,如能适宜地使用植物生长刺激素、微量元素及氮、磷等营养盐,可望得到良好的效果,但必须注意控制使用浓度,并与其他方面的因素配合,才能较好地发挥效用。
This paper reports the effects of several plant growth hormone, trace elements and nitrogen and phosphorus nutrients on the spore germination of Gracilaria tenu-istipitata. The results showed that: (1) Low concentration of ethephon (about 10 ppm) had a positive effect on the spore germination of Myrica cinerea; (2) The inhibitory effect of ethafene (40 ppm) Of the germination has a promoting effect; (3) fine-based Jiang Mi spore germination stage of the application of nitrogen and phosphate fertilizer have a positive effect. In addition, the effects of two trace elements, molybdenum and manganese, on the spore germination of Phlox glabrata were also discussed. When spore culture seedlings spawning, if appropriate use of plant growth hormone, trace elements and nitrogen, phosphorus and other nutrients, is expected to be good results, but we must note that the use of concentration, and other factors In order to better play its effectiveness.
