Biological activities of sponge gourd ' s bleeding sap on fungi 丝瓜伤流液对真菌的生物活性简报
Abstract : the influence of bleeding sap and nitrate - nitrogen , amino acid in root sap of k4 which grown in the zone is researched in seed treatments and initial bloom stage after spraying on leaf with edta - mn 摘要以“垦农4号”为材料,利用锰浸种和初花期叶面喷施,在小区试验的条件下研究了锰对大豆根系伤流量、伤流液中硝态氮和氨基酸含量调控的效应。
The effect of different dose of manganese mixed with seeds is not obvious on the soybean bleeding sap and content of nitrate - nitrogen and amino acid ; proper dose of manganese spraying on the leaf can improve the content of nitrate - nitrogen in bleeding sap obviously , to ck and the high dose of manganese treatment 不同浓度锰浸种对大豆伤流液中硝态氮与氨基酸含量影响不是很明显;适量锰叶面喷施可明显促进大豆伤流液中硝态氮与氨基酸含量,使其高于对照与高浓度锰处理。
Studies have been made shown that under water stress , not only root weight , root specific surface area , root - shoot ratio , root growing potential , root water potential , root vessel diameter , etc which express the indexes of wheat root morphology and architecture have significantly changed , but also bleeding sap , root respiratory rate , root plasma membrane permeability , plasmalemma peroxide level , root protective enzymes and its isoenzymes etc which express root physiological indexes have changed correspondingly 过去进行的研究表明,干旱胁迫条件下,不仅表达小麦根系形态和构型建成指标的根系数量、根系比表面积、根冠比、根生长势、根水势、根导管直径等发生显著变化,而且表达根系生理指标的伤流液、根呼吸速率、根系质膜透性、膜脂过氧化水平、保护酶及其同工酶等也发生相应改变。
