查询词典 nutrient solution

The results show that the duration of the 3 phases during the culture of cell suspension is related to the inoculum size, the initial nutrient concentration, the feeding of nutrients and the culture conditions such as temperature and dissolved oxygen, that the maximum cell yield reaches about 12g/L for batch culture or 35g/L for fed-batch culture in dry weight, that the saponin content of cells quickly increases in the bloom phase and keeps on increasing until the early stage of the declining phase, with a maximum saponin content of about 60~70g/kg in dry weight, that the conductance value of cell suspension decreases from more than 8000μS to less than 600μS with the growth of cells, but increases when the cells autolyze, and that part of cells turns red in the later culture, which has no apparent effect on the saponin content.

结果显示：细胞3个生长时期的持续时间与接种量、初始营养浓度、营养流加情况及培养条件有关；分批培养和流加培养时的最大细胞得率分别为12g/L和35g/L；细胞的皂甙含量在旺盛生长期快速上升，并保持增长至衰退期前期；干细胞中最大的皂甙含量达60~70g/kg；随着细胞的生长，培养液的电导值从8000μS以上下降至600μS以下，细胞自溶后逐渐回升。另外，培养后期部分细胞颜色变红，但没有发现颜色转变对皂甙含量造成影响。

Base on these phenomena, this study investigated the different responses of roots of these two species to cinnamic acid, in respect of the metabolism of reactive oxygen species, metabolism of water in plant, nutrient ion uptake and the growth in order to clarify the mechanism of the autotoxic effect of cinnamic acid on cucumber.

基于这一有趣的现象，本研究以黄瓜及黑籽南瓜为材料，通过对比研究两者受到自毒物质肉桂酸(cinnamic acid，CA)侵害时在活性氧代谢、水分代谢、养分吸收及生长等方面的响应差异，进一步探讨CA对黄瓜生理代谢过程的影响机制，主要结果如下： 1 0.25mM CA处理3天激发了黄瓜根系质膜NADPH氧化酶活性的显著提高，增加了活性氧H_2O_2和O_2~

Main obstacle reasons in soil of succession planting vegetables in protected cultivation were reviewed from soil maleficent microorganism increment, soil-borne diseases and insect pests to aggravation, soil nutrient imbalance, soil hypo-salinization, soil acidification and plant autotoxicity.

0引言随着我国蔬菜生产的发展，设施蔬菜栽培面积不断扩大，由于设施栽培的特点是采用人工控制，使设施内部形成了一个特殊的生态环境，且多年连作和大量施用化肥，忽视有机肥使用等，使蔬菜生产出现了各种障碍问题，其严重影响了蔬菜生产和农民收益，并成为制约蔬菜生产可持续发展的瓶颈问题。

A comparative study on the variations of nutrient content and caloric values of Avicennia marina, Aegiceras.

Corniculatum and Rhizophora stylosa during winter showed that nutrient content and caloric values of R, stylosa which was introduced from low latitude varied more than that of Avicennia marina and Aegiceras corniculatum which were native. R. stylosa had lower caloric values than the other two species

对白骨壤、桐花树和红海榄的比较研究表明，种源近期来自纬度较低的红海榄在越冬期间叶片营养物质含量和热值变化幅度最大，表明其对低温较其它两种更为敏感，其热值含量也低于当地自然分布的白骨壤和桐花树。

The factors of dissolved oxygen concentration, hydraulic retention time, nutrient, pH value, temperature and backwashing cycle, which affected the treatment efficiency of spent caustic wastewater were investigated.

To investigate the distribution of heavy metals and nutrient elements in plants along Quanzhou Bay, the distribution characteristics of Cu, Zn, Pb and N, P, K in Aegiceras corniculatum, Phragmites australis, Alternanthera philoxeroides, Basella rubra, Alternanthera sessilis, Solanum nigrum, Limonium sinense and Chenopodium albumas well as related soils were analyzed.

为了解泉州湾海岸带植物重金属及营养元素分布情况，研究了泉州湾海岸带常见植物桐花树、芦苇、空心莲子草、落葵、中华补血草、藜、莲子草、龙葵等的根、茎、叶等器官及其栖息土壤中的Cu、Zn、Pb及N、P、K含量分布特点。

In the process of root cutting, the root accumulated a lot of soluble sugar and soluble protein, which provided material and energy for the cell differentiation. As root differentiating, soluable protein was continuously used up. During 10 to 20 days, the content of soluble sugar and soluble protein in the basipetal top and end of rootkept comparatively stable, then declined as adventitious buds and roots growing. 40 days later, they kept invariable, because the newly formed bud can photosynthesize and the newly formed root can absorb nutrient from outside. The dynamic balances of endogenous hormone regulate adventitious buds and roots of the root. During callus growing and adventitious bud differentiating.

上部根段在细胞分化前期积累了大量的可溶性糖，为后期的分化提供能源物质，同时积累了大量的可溶性蛋白质，为愈伤组织的产生提供能源，而后随着分化，可溶性蛋白质不断被消耗。10～20d根段上部及下部的可溶性糖、可溶性蛋白质含量保持在相对稳定的水平变化不大，后期随着不定芽及不定根的生长下降较快。40d后，新形成的芽已经能够进行光合作用，新形成的根也可从外界吸收营养物质，可溶性糖、可溶性蛋白质含量基本保持不变。
