Phytoalexins are low molecular weight chemicals that plants produce and accumulate in response to infection especially of fungal origin. sakuranetin is a kind of flavanone phytoalexin isolated from ultraviolet - irradiated rice leaves. recent research work on flavanone phytoalexins represented by sakuranetin is reviewed. interesting novel structures, stucture - activity relationships and synthetic methods are discussed
植物抗毒素是植物受到外界病原微生物侵擾后所產生並積累的一類具有抗菌活性的小分子物質，櫻花素是從水稻稻瘟病感染組織中分離鑒定的一種黃烷酮類植物抗毒素.對以櫻花素為代表的水稻抗毒素及其類似物的結構與活性、黃烷酮類植物抗毒素合成方法的研究概況進行了綜述 -
In the present study, a compartment cultivation system and histochemical staining were used to investigate the influence of soil available p level, plant p status and soil organic p on the growth and metabolic activity of am fungi. differences in metabolic activity among am fungal isolates and the relationship between metabolic activity and mycorrhizal effectiveness were al so investigated. in addition, am fungi from a wide range of environmental conditions ( originally isolated from north, central and south china ) were used to study the ecological adaptability of am fungi and the influence of edaphic conditions on am fungal growth and metabolic activity
本研究採用分室根箱、組織化學等手段研究了土壤施磷水平、植物磷營養狀況、土壤有機磷對am真菌生長和代謝活性的影響；不同am真菌的代謝活性及其與菌根效應之間的關系，並對我國華北、華中和華南地區篩選出的高效菌株進行了生態適應性的比較，以期在理論上闡述宿主植物生長狀況及土壤條件對菌根真菌生長和代謝活性的調控機制，篩選出具有廣泛生態適應性的am菌株。 -
Study on anti - fungal activity of arnebia euchroma pigment of fulvia fulva
紫草色素對番茄葉霉病菌的室內抑菌活性研究 -
The results showed that the n - butanol and chloroform fractions had a stronger inhibitory activity to fungal growth and the n - butanol fraction had a stronger inhibitory activity to the bacteria, so that it was surmised that alkaloids in sophora alopecuroides were the major ant - fungal component, and flavonoid glycosides and triterpene glycosides in the n - butanol fraction had both anti - bacterial and anti - fungal activities
結果表明，正丁醇萃取部分和氯仿萃取部分對真菌生長有較強的抑制活性，正丁醇萃取部分對細菌亦有較強的抑制活性，推測苦豆子中的生物堿是主要的抗真菌成分，存在於正丁醇萃取部分的黃酮和三萜類配糖體等成分同時具有抗真菌和抗細菌活性。 -
Alkaline phosphatase ( alp ) activity in the intraradical hyphae could reflect the functional differences among am fungal isolates. alp activity in intraradical hyphae at early growth stage was a useful physiological index for predic
Am真菌根內菌絲的堿性磷酸酶活性在一定程度上反映了不同真菌功能之間的差異，植物生長前期的根內菌絲堿性磷酸酶活性可以作為預測菌根效應的簡易生理指標。 -
A hypothesis was suggested as following : firstly, the host plants could not synthesize enough carbohydrate to meet their own growth requirements and those of the fungus when the plant in experiment conditions of severe p deficiency. as a result, extraradical hyphal growth and am fungal metabolic activity were inhibited and therefore decline
宿主植物磷營養狀況較差時，菌根真菌生長和代謝活性旺盛；宿主植物磷營養狀況較好時，菌根真菌生長和代謝活性受到抑制，表明宿主植物的磷營養狀況對am真菌的生長和代謝活性具有調控作用。 -
The growth of extraradical hyphae and metabolic activity of am fungi changed with the application rate of fertilizer p added to the soil. fungal metabolic activity decreased with increasing addition of inorganic p to the soil and increasing plant p concentration
主要研究結果如下：不同的施磷水平對am真菌生長和代謝活性有一定的調控作用，隨著施磷量的增加、植物磷含量提高， am真菌代謝活性呈下降趨勢。
