Adding N, P could improve cucumber root activity, increased the absorptionof N, P and Mg, decreased that of K; Adding N improved the contents of Ca,Fe, Mn and Zn in leaves, and adding P accelerated absorption of cucumberroot to Fe. Adding K decreased the contents of N, P in leaves, but increased K,Fe content, contents of Ca, Mn and Zn decreased at the same time.4.

The comparison of contents of carbohydrate and hormone in cucumber roots,the root dry weight,soluble sugar content,glucose content,sucrose content,fructose content were higher,but starch contents werelower,and the contents of ZT,GA and IAA in xylem sap and roots were higher in G1 treatment,but ABA content was lower.However,the root dry weight significantly decreased in non-ventilation treatment(F1),and starch content,soluble sugar content,glucose content,fructose content were the trend of the dropping after the first rising, and sucrose content was lower,and the contents of ZT,GA and IAA in xylem sap and roots were lower,but ABA content was higher.

不同处理黄瓜根系碳水化合物含量和激素含量比较发现，G1通气处理根系的干重、总可溶性糖、葡萄糖、蔗糖和果糖含量均较高，淀粉含量较低，根系和伤流液中ZT、GA_3和IAA含量均较高，ABA含量较低；而非通气处理(F1处理)与对照相比根系干重显著降低，根系内淀粉、总可溶性糖、葡萄糖以及果糖含量均呈先升高后降低的趋势，而蔗糖含量较低；根系和伤流液中ZT、GA_3和IAA含量均较低，ABA含量较高。

So the present study was taken to compare the differences in the mechanisms of dissipating excess light energy in cucurbit crops and to study the differences in both the ROS metabolism in root system and the photosynthesis among six cucurbit crops with different temperature tolerance growing at different root-temperatures. The main results are as follows: 1、The species specific response of three cucurbit crops with different heat-tolerance: warm-adapted cucumber, heat-tolerant sponge gourd and heat-sensitive figleaf gourd to diurnal changes in air temperature and irradiance intensity were investigated in a typical summer sunny day. Three cucurbit species were compared using parameters in gas exchange, chlorophyll fluorenscence, photon allocation and photosynthetic electron flux.

因此，本试验以温度敏感性不同的瓜类作物为材料，研究了夏季自然条件下不同物种间在耗散过量光能的主要机制差异；探讨了它们对不同根际温度在根系活性氧代谢及地上部光合作用等方面的生理响应差异，所取得的主要结果如下： 1、在夏季晴天条件下，三种温度敏感性不同的瓜类作物：喜温的黄瓜，耐热性的丝瓜与热敏感的黑籽南瓜在气体交换、叶绿素荧光、光能分配及光合电子流对一天中温度与光照环境变化的响应上存在物种间差异和日变化特征。

With the increasing of NO3- concentration, the biomass, root absorbability and root absorbing area declined under NaNO3 treatment. The biomass was gradually increased with NO3- concentration increasing under Ca(NO3)2 and KNO3 treatments, while NO3- concentration excessed 98 mmol·L-1, the fresh weight of cucumber seedlings was gradually decreased.

NaNO3处理条件下，随着NO3-浓度增加，黄瓜幼苗生物量降低、根系吸收能力及吸收面积下降；而低浓度Ca(NO3)2及KNO3处理下，黄瓜幼苗生物量随着NO3-浓度增加而增加，当大于98 mmol·L-1时，黄瓜幼苗鲜重逐渐降低。

To investigate the response of plant growth and antioxidant system to changes of root temperatures, roots of six cucurbit plants were exposed to three different root-zone temperatures: low (14℃), middle (24℃) and high (34℃), while aerial parts of plants were maintained at the same natural ambient temperatures (23-33℃). The six cucurbit plant species could be classified into three groups with figleaf gourd and turban squash being I group (heat-sensitive but cold-tolerant), cucumber and melon being II group (heat- and cold-sensitive) and bitter melon and wax gourd being III group (heat-tolerant but cold-sensitive), i.e.

为了探究植物生长与活性氧代谢对根际温度变化的响应，以六种温度敏感性不同的瓜类作物为试材(组Ⅰ，黑籽南瓜与美洲南瓜，耐冷但热敏感型；组Ⅱ，黄瓜与甜瓜，冷敏感与热敏感型；组Ⅲ，苦瓜与冬瓜，冷敏感但耐热型)，分别将其根系置于不同的温度环境中：低(14℃)、中(24℃)与高(34℃)三种温度条件下，而地上部保持与外界空气相同的温度(23-33℃)环境中。

These parameters did not differ from each other in figleaf gourd"s two treatments. The root temperature of 14℃didn"t induce significant changes in the total respiration rate in both species but caused an increase of the alternative respiration pathway and a decrease of the cytochrome respiration pathway, and more dead cells in root tips in cold-sensitive cucumber roots.

低温条件下，黄瓜的生长明显差于黑籽南瓜，同时根系表现出更高的超氧化物阴离子O_2~(·-产生速率、过氧化氢(H_2O_2)与膜脂过氧化产物丙二醛含量以及抗氧化酶活性。14℃根温并未引起两种作物根系的总呼吸速率发生变化，但却引起黄瓜根系的交替途径呼吸速率与细胞色素途径呼吸速率的显著变化，表现为低温下Valt的上调而Vcyt的下降。
