脫葉綠素
英文
dechlorophyllization-
The ps ii native fractions ( 20 % and 30 % ) were loaded onto a deae column. the fraction eluted with 150 mm nacl was presented dcip reduction activity and was highly depleted in chi c and xanthophylls, and as such could be considered a ps ii core complex
對于有dcip光還原活性的20和30層帶的復合物,進一步deae離子交換層析純化。 150mmnacl洗脫純化后的樣品經過熒光激發光譜測定發現,已經去除了葉綠素c和墨角藻黃素,並且仍然具有dcip的光活性,分析是ps核心復合物。And hot is sensitive to the light, the saponifiable hydrolisis becomes emerald in the thin lye the chlorophyllin, the phytol and the methyl alcohol, may assume darkly in the acid solution green to green brown escapes the magnesium chlorophyll
對光和熱敏感,在稀堿液中可皂化水解成鮮綠色的葉綠酸、葉綠醇及甲醇,在酸溶液中可呈暗綠至綠褐色脫鎂葉綠素When inadequate n was added, the chloroplast structure in mesophyll cell was damaged in ear leaf, the amount of carbohydrate decreased in mestome sheath, and excessive n - redistribution and n - transportation to grain from vegetative mass appeared, which resulted in earlier leaf senescence. excessive n application led to too high activity of nitrate reductase, excessive vigorous nitrogen metabolism and too much exhaustion of carbohydrate in ear leaf, which resulted in the lack of enough carbohydrate in the lower leaf, meanwhile, the expansive chloroplast grana lamellae in leaf mesophyll cell and starch grain without nuclear in mestome sheath cell was observed, which led to the decrease of chlorophyll content and photosythetic capacity in maize leaf, then the early senescence occured
氮肥用量不足導致穗葉葉肉細胞葉綠體結構性差,維管束鞘細胞碳水化合物累積減少,營養體氮素再分配率大而引起葉片早衰;而過量供氮則導致生長後期硝酸還原酶活性過高,氮素代謝過旺,消耗了大量碳水化合物,以致下位葉不能得到充足的碳水化合物供應而提早脫落,同時葉肉細胞葉綠體片層結構膨脹,呈「肉汁化」特徵,維管束鞘細胞澱粉粒大量消耗,無核澱粉粒出現,從而葉片葉綠素含量下降,光合能力降低而出現早衰。1, 2. 3, 4, 5, 6 respectively. with the increase of lead level, the changing trend of spad and soluble sugar content and the activity of nitric acid reverting enzyme ( nr ) had appeared the same direction, which ascended first and then fell
2植物對pb污染的生理生態效應為了揭示pb污染對富集pb植物的生理代謝活動的影響,測定了葉片葉綠素含量、可溶性糖含量、硝酸還原酶的活性和脫落酸含量等生理指標。The study on chlorophyll contents and day change of photosynthetic in virus - free young jujube tree
