查询词典 cultivar

The Φ(subscript PSⅡ), Fv/Fm and qP were increased but qN was decreased with increasing of chlorophyll a, the rate of heat dissipation was increased with the increasing of chlorophyll b, and the carotinoid increasing enhanced the rate of heat dissipation of dryland and carbon assimilation of irrigated cultivar The Φ(subscript PSⅡ) and qN of dryland cultivar treated by control were higher than that of irrigated cultivar in jointing stage significant, indicating that the characteristics of drought-resistantce of winter wheat could be displayed in the jointing stage, and the drought-resistant capability could be increased by enhancing the practical photochemistry efficiency and heat dissipation in jointing stage.

One experiment was carried out with cotton (Gossypium hirsutum cultivar 86-1), soybean (Glycine max cultivar Ludou 11) and corn (Zea mays cultivar Yedan 13) inoculated with 3 AM fungi, Gigaspora margarita, Glomus intraradices, and Glomus versiforme to determine CP and another experiment was set up with red clover inoculated with 100, 300, 900, 2 700 and 8 100 IP of Gim, Gi, or Gv per pots (15 × 20 cm) filled with sterilized sand to test the relationship between IP and CP, and to test if CP can be used as a quality indicator.

用棉花、大豆、红三叶和玉米和3种AM真菌Gigaspora margarita， Glomus intraradices， and Glomus versiforme不同剂量(100， 300， 900， 2 700 and 8 100接种势单位)的接种物进行试验，以定量测定CP、以及CP和IP之间的关系。

In the seedlings time, the content of chlorophyll decreased by the deficiency of B, but the content of chlorophyll in the high efficiency cultivar decreased slowly than that of the low efficiency cultivar. This suggested that the leaves of the high efficiency cultivar can capture more light energy and the photosynthetic rate of the high efficiency cultivar decreased slowly. In the bolting time and blooming time, after two weeks of B deficiency treatment, the content of chlorophyll in the top leaves of the high efficiency cultivar decreased, and in the late time, the content of chlorophyll decreased slowly. But, the content of chlorophyll in the bellow leaves of the two cultivars had little changes. The reason may be that B in the high efficiency cultivar distributed to the propagative organ in the late growth, and the leaves were short of B.

苗期，缺硼导致甘蓝型油菜色素含量降低，且高效品种色素含量下降的幅度小于低效品种，表明营养生长阶段，同等程度的缺硼条件下，高效品种叶片对光能的收集能力以及光合速率下降的程度相对较小；苔期和花期，在两周的缺硼处理后，高效品种上部叶色素含量依然呈下降趋势，但随着生育期的推移，其下降幅度减小；而高效品种下部叶和低效品种叶片含量变化不大，可能是甘蓝型油菜进入生殖生长阶段后，高效品种将硼更多地分配到繁殖器官，而其叶片却承受了相对较大的缺硼胁迫。

In addition, the hypha could also invade the rice root.3、Making clear the effects of silicon on the resistance to sheath blight and rice growth.Sodium silicate was added into the nourishing in the entire growth period and short period of rice, after being inoculated with R.solani, the rice with application (the Si+ rice) of resistant cultivar 91SP and Teqing had lower (but not statistically significant) disease rating and disease index with relative control effect of 10.02% and 8.70% compared to the Si- rice plants in, but the Si+ rice plants of susceptible cultivar Lemont and Ningjing 1 had significantly lower rating and disease index with relative control effect of 27.42% and 24.29% compared to the Si- rice plants. The results indicated silicon could strengthened the resistance to rice sheath blight, specially strengthened the resistance of susceptible cultivar Lemont and Ningjing 1 remarkedly.

纹枯病菌也能侵染水稻根部。3、明确了施硅对纹枯病的抗病效应和水稻生长的影响全生育期和短期在营养液中添加硅水培水稻试验结果表明，施硅减轻了病级和病情指数，施硅对抗病品种91SP和特青的相对防治效果分别为10.02%和8.70%，而对感病品种Lemont和宁粳1号的相对防治效果达27.42%和24.29%，说明施硅增强了水稻对纹枯病的抗性，特别显著增强了感病品种Lemont和宁粳1号的抗性。

The cytochemical localization of POD showed that the peroxidase was found in cells ofboth cultivars after inoculation. The activity of POD in resistant cultivar was higher than that innot only the uninoculated controls but also the inoculated susceptible ones and localized morewidely, such as localized in mesophyll cell wall, intercellular spaces, membranes of chloroplastand mitochondrion and vacuolar membrane. Whereas the POD in susceptible cultivar waslocalized mainly in cell walls but little in plasma membrane with a lower range and intensitythan that in resistant cultivar.
