1. Membrane lipids found in various parts of the plant, such as seeds, twigs,leaves, chloroplasts, etiolated seedling and callus tissues, are composed mainly ofphosphatidylcholine (PC), phosphatidylethanolamine (PE), phosphatidylglycerol(PG), monogalactosyl diglyceride (MGDG), phosphatidylinositol (PI), digalacto-syl diglyceride (DGDG) and sulfolipids (SL). The major components of fattyacias in the membrane .are palmitic(16:0), stearic (18:0), oleic (18:1), linoleic(18:2) linolenic (18:3), palmitoleic (16:1)...

1. Membrane lipids found in various parts of the plant, such as seeds, twigs,leaves, chloroplasts, etiolated seedling and callus tissues, are composed mainly ofphosphatidylcholine (PC), phosphatidylethanolamine (PE), phosphatidylglycerol(PG), monogalactosyl diglyceride (MGDG), phosphatidylinositol (PI), digalacto-syl diglyceride (DGDG) and sulfolipids (SL). The major components of fattyacias in the membrane .are palmitic(16:0), stearic (18:0), oleic (18:1), linoleic(18:2) linolenic (18:3), palmitoleic (16:1) acid and a few others.2. The degree of unsaturation of the fatty acid in the seeds of eight grapevarieties is positively correlated with the cold-resistance of the species and thevarieties.3. The proportion of the fatty acids in membrane lipids of grape twigschanged periodically with the change of season. The degree of unsaturationincreased when the field temperature decreased. After autumn the differencesbetween hardy varieties and tender ones become increasingly obvious. Thehardy varieties possess higher ratios of linoleic acid to palmitic acid.4. The major constituents of the as follows: DGDG, MGDG, SL,PC, PI.Linolenic acid (18:3) is the most abundant, followed by palmitic acid, lenoleicacid and palmitoleic acids. The proportion of fatty acids in chloroplast membranetaken chloroplast membrane lipids are from fields in September seems to haveSomething to do with their cold-resistant capacity of the plant. There was, how-ever, no obvious change or tendency to change and difference in the membrane fattyacids of the grape leaves throughout the summer.5. When etiolated grape seedlings and callus tissues were kept at 25℃ and then transferred to a 7℃ refrigerator for certain time, it was found that there wasan increase in the proportion of unsaturated fatty acid, which seemed to bear somerelation with their resistance to cold stress.From a number of experiments using various materials of the grape plant,it seems that the changes in the membrane lipids components are very complicated,yet rather regular. It seems to depend on both genetic and environmental fa-ctors. In general, the proportion of the membrane fatty acids in the grape plantseems to be correlated with the degree of cold-resistance of the species or the varie-ties.

分析了葡萄的种子、茎、叶、树皮、叶绿体、叶片愈伤组织和黄化幼苗的膜脂主要组分。种子的膜脂脂肪酸不饱和度与品种抗寒性成正相关。茎的膜脂脂肪酸含量随季节呈周期性变化,膜脂脂肪酸不饱和度随气温的降低而升高。秋季取样的茎、叶片、叶绿体的膜脂脂肪酸不饱和度与品种抗寒性成正相关。抗寒品种具有较高的亚油酸/棕榈酸比值,近亲品种的膜脂组分近似,可以看到遗传性的影响。夏季取样的茎、叶片、叶绿体的膜脂脂肪酸含量的变化无明显规律性,品种间无明显差异。25℃培养的黄化幼苗和愈伤组织经7℃处理后,两者的脂肪酸不饱和度都略有增加,,与品种的抗寒性也有一定联系。

The activity and isozymic patterns of the peroxidase (POX), polyphenol oxidase (PPO) and superoxide disrnutase (SOD) extracted from stem xylem in the nodes which were not the same degree of development of thre e-yead-old 'Kyoho' grape seedlings were analyzed by using the discontinuous system of poly acrylamid gel electrophorsis.

The activity and isozymic patterns of the peroxidase (POX), polyphenol oxidase (PPO) and superoxide disrnutase (SOD) extracted from stem xylem in the nodes which were not the same degree of development of thre e-yead-old 'Kyoho' grape seedlings were analyzed by using the discontinuous system of poly acrylamid gel electrophorsis. It was shoown that a specific band on the electrophoretogram of POX from stem segments increased in activity from the stem base up to the first-tendril position and then disappeared. During the rest period, no difference in enzyme patterns between development stages was found whereas during the growing season number and activity of POX increased steadily as the development of grapevine advanced. The isozyme pattern of SOD, however, remained unchanged with the advancement of the development process, regardless of whether the tissue was sampled from a dormant oractively growing plant More bands and higher actlvity of this isozyme were found during the dormant period. The zymograms of PX and PPO were proved to be identical.

采用聚丙烯酰胺凝胶电泳,分析了三年生巨峰实生苗阶段发育过程中不同节位木质部的过氧化物酶、多酚氧化酶和超氧物歧化酶同工酶谱带。结果表明:不同节位木质部的过氧化物酶同工酶的一条谱带,从茎基部到首次出现卷须的部位其活性增强,随后便消失。在休眠期,过氧化物酶同工酶不存在阶段发育的酶谱差异性;在生长期则随着葡萄蔓阶段发育程度的提高酶带数增多,活性增强。超氧物歧化酶同工酶,不论是休眠植株还是活跃生长的植株,其酶谱保持不变,但休眠期酶带多、活性高。过氧化物酶同工酶与多酚氧化酶同工酶酶谱类型一致。
