项目摘要

1) Effects of N, P and Mn deficiencies on the formation of anthocyanin and other phenolic compounds were investigated with seedlings of two cultivars of corn (Zea mass L.), Yellow dent (YD), rich in, and Golden crossbantam (GC), poor in anthocyanin. Nitrogen deficiency increased the contents of total plienol and flavanol in the leaves of both YD and GC more remarkably than P deficiency. For YD, P deficiency caused a drastic accumulation of anthocyanin in the leaves, while the accumulation by N deficiency was slight. On the other hand, anthocyanin in GC was scarcely changed by the deficiencies. Anthocyanin content in YD was scarcely increased when P and Mn was simultaneously deficient. The increase in leucoantliocyallin content caused by P deficiency was greater than that by N deficiency both in YD and DC. Phenolic acids contents in the leaves of both YD and GC were increased by P or N deficiency.2) Effects of Mn deficiency on plieyiol metabolism were investigated with seedlings of red … More lettuce (Lacutuca sativa L.) and red cabbage (Bracssica oleracea L.). After the seedlings were water-cultured with Mn deficient culture solutions, phenylalanine ammonia-lyase (PAL) activity, total phenol, anthocyanin, and chlorophyll contents were determined. Manganese deficiency caused decreases of PAL activity, total phenol and anthocyanin contents in the leaves of both red lettuce and red cabbage, among which the decrease of anthocyanin was more remarkable. The anthocyanin content changed unrelated with the chlorophyll content in the upper leaves of red cabbage. It is suggested that Mn has a direct function in phenol metabolism, especially in antliocyanin formation.3) Phenolic acids were determined in the leaves of kidney bean (Pliaseolus vulgaris L.) grown in nutrient solutions containing different concentrations of Mn. PAL activity and phenolic-acids contents were increased by the slight excess of Mn, while phenolic acids, especially caffeic acid were decreased by the severe excess.4) Silicon and Ca combined with cell wall of the leaf sheath of rice plants were investigated by molecular sieve chromatography. Silicon as well as Ca appeared to be combined with lignincarbohydrate complexes in the cell wall. Less

1)以两个玉米品种（Zea mass L.）幼苗为材料，研究了氮、磷、锰缺乏对花青苷和酚类物质形成的影响，黄马齿（YD），花色苷含量丰富;金雀花（GC），花色苷含量较低.氮素亏缺使YD和GC叶片中总酚和黄烷醇含量增加，但显著高于磷素亏缺。对于YD，缺磷导致叶片中花青素的急剧积累，而缺氮则导致花青素的轻微积累。另一方面，花青素在GC中几乎没有变化的缺陷。当P、Mn同时缺乏时，YD花色素苷含量几乎没有增加。无论是YD还是DC，缺磷引起的白细胞抗蓝蛋白含量的增加均大于缺氮引起的增加。缺磷或缺氮均使YD和GC叶片中酚酸含量增加; 2）以红葡萄幼苗为材料，研究了缺锰对叶片中酚酸代谢的影响 ...更多信息莴苣（Lacutuca sativa L.）和红甘蓝（Bracssica oleracea L.）。用缺锰培养液水培后，测定了幼苗苯丙氨酸解氨酶（PAL）活性、总酚、花青苷和叶绿素含量。缺锰导致红生菜和红甘蓝叶片PAL活性、总酚和花青素含量下降，其中花青素含量下降最为显著。红甘蓝上部叶花青苷含量的变化与叶绿素含量的变化无关。锰对酚类物质的代谢有直接的作用，尤其是对抗花青素的形成有直接的作用。生长在含有不同浓度锰的营养液中。轻度过量的Mn使PAL活性和酚酸含量增加，重度过量的Mn使酚酸特别是咖啡酸含量下降。4）采用分子筛层析技术研究了水稻叶鞘细胞壁中硅、钙的结合情况。硅以及钙似乎是结合在细胞壁中的lignarbohydrate复合物。少
