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)。

C, 200rpm for 5d then placed statically for more than 7d, and addition more than 0.01% Chitosan to Bacillus subtilis suspension provided significant UV protection. The survival spore rate is 90% about 2-2.5 fold better than control for spore exposed to UV radiation for 30 min. Bioassay in against Glomerella cingulata, and the inhibition activity is still 60%.

枯草杆菌於MIY液态培养基中，30°C，200rpm震荡培养五天后静置培养七天以上，以甲壳素添加浓度大於0.01％作为最适宜的紫外保护剂之作用最好，於UVB灯下暴晒30 min，对枯草杆菌孢子的保护效果最好，存活率达90％以上，抗紫外线活性是不添加紫外线保护剂的CK组的2.5-3倍，对檬果炭疽真菌仍有60%的抑菌活性。

"That can cause real problems, because that remaining 10 percent of patients — who may have look-alike conditions such as multi-system atrophy or progressive supranuclear palsy — end up getting treated with Parkinson's drugs," Dr.

&这确实是个问题，因为剩下10％的病人－他们可能患有诸如多系统萎缩或进行性核上性麻痹的疾病－最后则接受帕金森病药物的治疗，&Beal博士说，&这些药物也许能起一时之效，但同时，他们并未能接受最适宜的治疗。&

Unwooded to offer optimum juicy fruits reminiscent of red berries.

无树木生长的环境为多汁水果尤其是令人留恋的红色浆果提供了最适宜的生长环境，这种果实酿造了此款非常诱人而且易于饮用的葡萄酒。

Cape Wind and its 130 turbines would be located in what may be the most propitious offshore site in the country: shallow water protected from heavy waves; strong, steady winds; and proximity to consumers and industries that would benefit from its power.

&海角风&项目的130座风力涡轮机将坐落在也许是这个国家的最适宜的海岸上：不见巨浪肆虐的浅水，稳定的强风，附近的消费者及工业也将因该能源获益。

The effect of reaction temperature,reaction time,materials ratio on the synthesis of piperidine alcohol benzoate ,hindered amine light stabilizer,from piperidine alcohol and benzoyl chloride by direct condensation were studied,and the proper technological conditions were given as follows:the reaction temperature is 95℃;reaction time is 4 h; the mole ratio of reactants,n∶n is 1∶1.4,the amounts of solvent is 40 mL(based 0.1mol piperidine alcohol),the arerage yield ...

王树清，高崇，苯甲酸哌啶醇酯HALS的合成工艺研究研究了以苯甲酰氯和哌啶醇为原料直接缩合合成苯甲酸哌啶醇酯受阻胺光稳定剂时反应温度、反应时间、原料配比等条件对合成反应的影响，确定了最佳工艺条件。最适宜的工艺条件是：反应温度95℃、反应时间6h、原料摩尔比n∶n为1∶1.4，溶剂用量为70mL(相对于0.1mol哌啶醇)，苯甲酸哌啶醇酯的收率为91.05%，产品纯度98.5%。

The sudden appearance of yellow leaves on plants accustomed to acidic soils-such as azaleas, hydrangeas, and gardenias-could signal a drop in the plant's iron intake or a shift in the ground's pH above a comfortable 5.0 level.

适合酸性土壤的植物，如杜鹃花，绣球花和栀子花等突然出现黄叶的时候，说明植物吸收的铁离子有所下降，并且土壤的酸度改变了，PH值大于植物最适宜的5。
