Changes of chlorophyll metabolism during the albinic stage including both degreening and regreening processes were studied. The results indicated that an decrease of Caro content was not the cause of mutant degreening and that the mutant belonged to the total Chl dificient type.The changes of Chlase activity level indicated that Chl breakdown was not the main factor which led to degreen of the mutant.A greater changes of content of intermediates of Chl biosynthesis during the albinic period δ aminolevulinic...

Changes of chlorophyll metabolism during the albinic stage including both degreening and regreening processes were studied. The results indicated that an decrease of Caro content was not the cause of mutant degreening and that the mutant belonged to the total Chl dificient type.The changes of Chlase activity level indicated that Chl breakdown was not the main factor which led to degreen of the mutant.A greater changes of content of intermediates of Chl biosynthesis during the albinic period δ aminolevulinic acid (ALA) and porphohilinogen(PBG) were accumulated,but uroporphyrinⅢ(Uro Ⅲ),protoporphyrin Ⅸ (Proto Ⅸ),Mg protoporphyrin Ⅸ(Mg Proto Ⅸ) and protochlorophyll(ide) (Pchl(lide)) were decreased.Specialy during the degreening process Uro Ⅲ was gradually decreased,but an initiation of regreening,the Uro Ⅲ was markedly accmulated.It was proved that there was a blockage in Chl biosynthesis in the mutant,which could be somewhere in the formation of uroporphyrinogen Ⅲ(Urogen Ⅲ).

小麦 ( Triticum aestivum)返白系在返白阶段 Chl、胡萝卜素 ( Caro)含量均下降 ,但 Caro/ Chl的比值大于对照 ,表明叶片白化不是因 Caro减少引起的。Chl下降的同时 ,Chla和 Chlb均下降 ,表明该突变体属阶段性缺总 Chl型。返白初期 Chlase活性增高 ,返白中期活性下降 ,表明 Chl降解不是造成叶片失绿的主要原因 ;Chl合成中间物 δ-氨基酮戊酸 ( ALA)、胆色素原 ( PBG)积累 ,尿卟啉 ( Uro )、原卟啉 ( Proto )、镁 -卟啉 ( Mg- Proto )、原叶绿素酸 Pchl减少 ,特别是 Uro 在返白中期含量最低 ,复绿初期却急剧积累 ,表明叶绿素合成受阻于尿卟啉原 ( Urogen )的形成上。

In order to approach the mechanism of drought resistance, the drought resistane of Larix olgensis and Pinus sylvestris var. mongolica etc. were studied, the results indicate that at different period of natural loss of water, water parameters of different tree species were different, and their change speed were different either. At all period, the speed of water loss was the biggest in Fraxinus mandshurica Rupr and Larix olgensis Henry; that in Picea koraiensis Nakai came second, and that in Pinus sylvestris...

In order to approach the mechanism of drought resistance, the drought resistane of Larix olgensis and Pinus sylvestris var. mongolica etc. were studied, the results indicate that at different period of natural loss of water, water parameters of different tree species were different, and their change speed were different either. At all period, the speed of water loss was the biggest in Fraxinus mandshurica Rupr and Larix olgensis Henry; that in Picea koraiensis Nakai came second, and that in Pinus sylvestris var. mongolica and Pinus tabulaeformis Carr. was the smallest. The speed of water loss had a direct bearing on other water parameters. The relative permeability of cell membrane was the smallest in Larix olgensis and Fraxinus mandshurica , that in Pinus tabulaeformis came second, and that in Pinus sylvestris var. mongolica and Picea koraiensis was the biggest. The order of the influence of dehydration on chlorophyll metabolism of different tree species from big to small was Fraxinus mandshurica , Picea koraiensis/Pinus tabulaeformis, Pinus sylvestris var. mongolica, Larix olgensis. The mechanism of drought resistance in Larix olgensis and Pinus sylvestris var.mongolica was different. Larix olgensis was drought-enduring tree species of dehydration-enduring; while Pinus sylvestris var. mongolica was drought-enduring tree species of dehydration-deferring. The mechanism of drought resistance in Picea koraiensis belonged to middle pattern, that in Fraxinus mandshurica was similar to Larix olgensis, while that in Pinus tabulaeformis was similar to Pinus sylvestris var. mongolica.

为研究树木的抗旱机制,文中对长白落叶松、樟子松、红皮云杉、油松和水曲柳的抗旱性进行了探讨。结果表明,自然失水不同时期,各树种的水分参数不同,其变化速率也不同。各时期均以水曲柳和落叶松失水速率最大,红皮云杉次之,樟子松和油松失水速率最小;与之相关的各树种其它水分参数变化由快到慢的顺序也如此。落叶松和水曲柳的质膜相对透性较小,樟子松和红皮云杉较大,油松质膜相对透性居中;脱水对各树种叶绿素代谢的影响由强到弱依次为水曲柳、红皮云杉/油松、樟子松和落叶松。落叶松与樟子松的抗旱机制不同,落叶松属于忍耐脱水耐旱树种,而樟子松属于延迟脱水耐旱树种,水曲柳与落叶松相似,油松与樟子松相似,红皮云杉抗旱机制属中间类型。

The changes of chlorophyll content and protein content and several enzyme activities in the leaves were studied during the period of appearing zebra\|leaf character from the thermo\|sensitive rice line 1103S and Wujin 4B. The results indicated that the chloropyll and carotenoid content and the protein content and the SOD and CAT activities decreased and POD activity increased after the appearing zebra\|leaf character. However, it was found that every index was reversible in the process of recovery of the yellow...

The changes of chlorophyll content and protein content and several enzyme activities in the leaves were studied during the period of appearing zebra\|leaf character from the thermo\|sensitive rice line 1103S and Wujin 4B. The results indicated that the chloropyll and carotenoid content and the protein content and the SOD and CAT activities decreased and POD activity increased after the appearing zebra\|leaf character. However, it was found that every index was reversible in the process of recovery of the yellow part of the leaves into green. It was suggested that the expression of zebra\|leaf character might be due to abnormal chlorophyll metabolism. It was related to the content of pigment and the enzyme activities of POD, CAT, and SOD.

以具“斑马叶”性状的水稻 110 3S、武金 4B以及对照武金 3B为材料 ,研究了该性状表达过程中叶片叶绿素、蛋白质含量及几种酶活性的变化 .结果表明 ,性状表达期叶片叶绿素、蛋白质含量减少 ,过氧化氢酶 ( CAT)和超氧化物歧化酶 ( SOD)活性降低 ,过氧化物酶 ( POD)活性上升 ;随着叶片复绿 ,各项指标又回复到低温处理前的水平 .该性状的表达是由于阶段性叶绿素代谢异常所致 ,它不仅与叶绿素含量有关而且与 POD、CAT、SOD等几种酶活性之间存在一定关系
