Abstract:1982—1985年,通过大田调查和小区试验的研究结果,小麦播种后,12月下旬显病,根据该病症状在田间的发展变化可划分为始病期、缓增期、急增期和恢复期。本病的传播主要通过病土和病株残根,传毒率相应为67.5—98%、5.5—88%;种子、蚜虫、飞虱不能传毒。自然条件下,病毒仅侵染小麦。病毒粒体直径为12—14nm,长度为100—350nm,不同于国内外文献中所已报道的其它小麦花叶病类的病毒。

Abstract:本文报道了农抗SH—62产生菌原生质体再生菌株的筛选和再生菌株R—4的发酵规律。试验表明,通过摇瓶的初筛和复筛,从活性比出发菌株要强的202株再生菌株中,找出R—4、R—66和R—72三株活性最强而又稳定的再生菌株。在再生菌株R—4的发酵试验中,选出了该菌株的最佳发酵培养基为1号培养基,并证明这个菌株对溶氧量并不敏感,在偏碱条件下有利于生长和产素,发酵周期为72小时等最适发酵条件。
