【摘要】 研究了開設(shè)誘導(dǎo)孔的方式誘導(dǎo)鹿角靈芝(Ganoderma amboinense)形成原基的方法,結(jié)果表明:鹿角靈芝在菌絲完全發(fā)滿菌包或發(fā)滿菌包至3/5以上時(shí)可以通過在菌包肩部下方1~2cm處開2個(gè)誘導(dǎo)孔誘導(dǎo)原基形成,這種誘導(dǎo)方法較常規(guī)方法可使菌絲未發(fā)滿的菌包提前20~30d形成原基;還可將原基形成率從52%提高至82%~94%,增產(chǎn)55%~186%;使用誘導(dǎo)孔處理未完全發(fā)滿菌絲的菌包還可加速菌絲發(fā)滿菌包、加強(qiáng)菌絲長勢,增強(qiáng)子實(shí)體抗病能力。
【Abstract】 When grown in a plastic-covered cultivation house,Ganoderma amboinense fruit bodies were formed over the temperature range 23~33 ℃,although temperatures above 30 ℃ inhibited primordium formation and resulted in lower yields.The frequency of primordium formation was increased by punching ventilation holes halfway down or at the shoulder of the cultivation bags in which the substrate had been either 60% or fully colonized by the fungal mycelium.The frequency of primordium formation was higher(94%)...
