It was discovered that under low temperature, in the leaves of chemical-treated rice seedlings, SOD and POD activities and chlorophyll stability increased, cell viscosity enhanced, free proline accumulated and electrolyte leakage decreased. 低温胁迫下(6°C),药剂诱导水稻幼苗叶片中过氧化物酶、超氧化物歧化酶活性和叶绿素含量升高,细胞粘度增大,游离脯氨酸积累增加,以及叶片电解质渗漏量减少。
The results showed that under various temperatures and decreasing O_2 content in the drying media, in which N_2 and CO_2 were used as drying media to replace partial air, the chlorophyll content and mass fraction of vitamin C of the vegetables were improved. 结果表明:采用N2或CO2进行气体调节,降低干燥过程气体的O2含量,可明显提高蔬菜干制品叶绿素含量和降低干制过程维生素C质量分数的损失。
And ( 3) The ecological effect of Fe on algae growth was mainly expressed in influencing chlorophyll a synthetic rate, algae cellular division potential as well as C and N fixation rate. 铁对藻生长的生态学效应主要表现在对藻类的叶绿素a的生物合成、藻细胞的分裂,以及碳和氮的固定作用的影响。
Contents of chlorophyll a and chlorophyll b decreased, while content of carotenoid, ethylene release and weight loss increased during storage. 贮藏过程中花蕾的C值和H值增加,叶绿素a与叶绿素b含量下降,类胡萝卜素含量增加,花蕾的失重率和乙烯释放量增加,维生素C含量迅速减少。
Diurnal Changes of Chlorophyll Fluorescence Quenching and the Response to Photooxidation in Leaves of C_3 and C_4 Plants C3、c4植物叶片叶绿素荧光猝灭日变化和对光氧化作用的响应
Contents and apparent activation energies of chlorophyll and ascorbic acid of broccoli under controlled atmosphere storage 嫩茎花椰菜在不同气调贮藏下叶绿素和维生素C的降解及活化能研究
The content of chlorophyll, TSS, protein and vitamin C decreased, but the level of organic acid rose. It is concluded that after 4 days 'storage at room temperature, the commercial quality of Vigna sinensis fruits descented quickly. 豆荚叶绿素、可溶性固形物、蛋白质和维生素C的含量一直呈下降趋势,而豆荚有机酸的含量则上升,室温贮藏4d后豇豆的商业品质迅速下降。
In this experiment, the variant materials obtained by seed soaking method were tested for biochemical indices such as chlorophyll, soluble sugar, reducing sugar, protein and Vitamin C contents, as well as plant height, plant type, leaf area and growth period. 对应用浸种处理获得的变异后代,进行了叶绿素、糖、蛋白质、维生素C及株高、叶面积、生育期等的测定。
'Golden Edger' has lowest chlorophyll content and highest value of Ca/ Cb, while 'Elegans' the opposite. ‘GoldenEdger’叶绿素含量最低,Ca/Cb值最高,而‘Elegans’正好相反。
The chlorophyll content in vegetable increased significantly, while the vitamin C and NO~-_2 content decreased significantly after spraying total alkaloid from Sophora alopecuroides. 喷施苦豆子总碱后蔬菜叶绿素的含量显著增加,亚硝酸盐和维生素C的含量明显下降。
The results showed that synergist improved the contents of chlorophyll. 结果表明,增效剂处理能提高叶绿素含量,其中处理C叶绿素含量最高,对照最低;
Contents of chlorophyll a and b of treatment B, A, C for different gradients were always higher than those of check treatment; 生育期间各个坡度B、A、C处理的叶绿素a、b的含量始终大于D处理;
The HPLC results showed that under N limited condition, the Fucoxanthon/ Chlorophyll a and Chlorophyll c/ Chlorophyll a ratios were higher than those under P-limited and unlimited conditions; HPLC的结果显示在氮限制条件下,细胞的墨角藻黄素(Fucoxanthin)/叶绿素a、叶绿素c/叶绿素a比值高于磷限制和未受营养盐限制条件(对照组);
Spermine treatments could restrain respiratory intensity significantly, reduce the decomposition of Chlorophyll and Vitamin C, inhibit the rising of relative electrical conductivity and MDA content, decreased the rising of rot index and chilling index at ( 1 ± 1)℃. 低温(1±1)℃条件下,精胺处理可有效抑制青椒果实的呼吸强度,减少果实叶绿素和Vc含量的分解及MDA的积累,延缓相对电导率上升,降低果实腐烂指数和冷害指数的上升。
