Biological characteristics of Curvularia lunataBoedijn had been preliminarily studied. Optimal mediums for pathogen growth were PSA,PDA and OMA.For mycelia growth,sporulation and conidial germination of pathogen,optimal temperature was 25~30℃,and pH 5~9.Among the tested carbon and nitrogen resources,sucrose,glucose,carbamide,sodium nitrate,etc were beneficial for mycelia growth and sporulation.The conidia germination is strict in RH requirement:Conidia can germinate at RH 81%~98%,or have 100% germin...
香蕉大灰斑病菌适合生长的培养基有PSA、PDA和OMA;菌落生长、产孢和孢子萌发最适宜的温度为25~30℃,pH 5~9;在碳源和氮源中,蔗糖、葡萄糖、尿素、磷酸氢二氨和硝酸钠有利于病菌生长和产孢;分生孢子萌发对湿度有严格的要求,RH≥80%以上分生孢子萌发,随湿度增加萌发率增高;光照对菌丝体无显著影响,光暗交替有利于孢子的形成;孢子致死温度为55℃(10min)。

Research results of phase equilibrium for the KOH—K〓CrO〓—H〓O system, the KOH—KAlO〓—H〓O system and the KOH—K〓CrO〓—KAlO〓—H〓O system revealed that lower concentration of KOH was beneficial for the crystallization of KAlO〓, and within a certain range, higher concentration of KOH was favorable for the crystallization of K〓CrO〓.
KOH—K〓CrO〓—H〓O体系,KOH—KAlO〓—H〓O体系和KOH—K〓CrO〓—KAlO〓—H〓O体系相平衡研究结果表明,较低的氢氧化钾浓度有利于铝酸钾结晶析出,一定范围内,较高的氢氧化钾浓度有利于铬酸钾结晶析出,因此,通过控制氢氧化钾浓度可以使铬酸钾—铝酸钾—氢氧化钾得以分离。
