The gelatinous strength of hynean was affected by electrolyte markedly. Theorder of effect by cations is:Ca~(++)>K~+, Cs~+, Rb~+>Na~+, Li~+, NH_4~+, and by anionsis: Cl~->NO_3~-, SO_4~->I~->CO_3~-. 3. The setting point of hynean was affected by KCl, it was increased with increa-se of concentration of KCl. 4. The culturing effects of bacteria (Salmonella typhasa, Pasteure lla pestis,Shigella dysenteriae and Brusella abortus) in bynean media and in agar media werecompared. Hypean gave better results.

本文报道了对沙茶胶在提取方法、性质和应用等方面的初步研究结果。其提取方法是先将沙茶置于室温条件下用波美20°的Na0H处理2天,水洗后加入15-20倍0.04%的硫酸,100℃煮胶1-1.5小时,加入KCl至0.2—0.3%过滤(或过滤后加KCl),滤波放置凝固、冷冻、解冻,最后干燥后得产品。电解质对沙菜的凝固强度影响很大,对提高凝胶强度,阳离子的顺序是:Ca~(++)>K~+,Cs~+,Rb~+>Na~+,Li~+,NH_4~+;阴离子的顺序是:Cl~->NO_3~-,SO_4~->I~->CO_3~-。沙菜胶的凝固温度与加入的KCl浓度有关,KCl浓度大,凝固温度也随之升高。试验了四种细菌在沙菜胶培养基上的生长情况,结果表明细菌在沙菜胶培养基上生长的活菌计数甚至比在琼脂培养基上的还多。

水稻花药液体漂浮培养能大幅度提高愈伤组织诱导频率,但这些愈伤组织的分化能力很低。为了提高液体培养下愈伤组织的分化频率,试验了5种诱导培养基和4种分化培养基。结果表明,诱导培养基对愈伤组织分化能力的高低起主要作用,其中以过滤灭菌的马铃薯提取液培养基的效果最好,绿苗分化率可高达50%;分化培养基对愈伤组织分化频率的影响较小,且不甚规律。浮在液面上的愈伤组织比沉在培养液底部的愈伤组织有较高的分化能力。愈伤组织转移时间的早晚对分化频率也有很大影响。

The insect pathogenic fungus Erynia delphacis on brown plant-hoppers (Nilaparvata lugens) was collected from five Chinese southern provinces by Dr. D. W. Roberts, It was identified by Dr. R. A. Humber. In the present research five of the E. delphacis isolates, one from each province, were conducted as to conidia production in liquid and agar media.

飞虱虫疫霉 Erynia delphacis(Hori)是水稻害虫稻褐飞虱的天敌,在田间常造成流行病,使大量褐飞虱死亡。在研究利用真菌防治害虫方面,一个很重要的问题就是如何在人工培养基上培养病原菌,并获得大量可以保存的孢子然后用于田间。本试验的重点在于用液体培养的方法获得这种菌的分生孢子,并测定了液体和固体培养的产孢量和产孢时间。
