In nutrient solutions,deoxygenation caused a series of changes in root ana-tomy of some species,such as increased root diameter,root porosity and more developed aerenchyma,inducing a ROL barrier in root basal part and the consequent change of ROL profile.

溶液培养条件下，缺氧胁迫能使植物根的直径增粗，根孔隙度提高，通气组织更加发达，诱导根基部泌氧屏障的生成，使泌氧速率和泌氧方式发生变化。

Effect of different phosphate and bicarbonate concentrations on iron absorption in camphor tree seedlings was studied in sand culture experiment.

What's worse, they think that the temperature condition is not necessary for seeds to come into leaf and that plants can also grow well without fertilization.

学生对於植物生长的另有概念包括将根与茎的名词定义错误，认为植物是「先长茎再长根」或「先长果实，后开花」；并对植物器官的功能不熟悉；缺乏植物的「花」、「果实」具有传宗接代等繁殖概念；「温度」条件对种子发芽而言是非必要的；植物有「施肥」就长得更好，没有施肥也不会怎样；知道植物可以用种子繁殖，除了种子以外可以繁殖的器官学生多数只看过落地生根用叶子繁殖，缺乏更多的实际经验。

In the medium of H2SO4 with KBr as the catalyst, the color of Cresol Red oxidized by iodate can be faded, and the degree of color fading is proportional to the concentration of iodine and the linear range of determination is 20 μg/25 mL~50 μg/25 mL.

在硫酸介质中、在溴化钾催化条件下，碘酸根对甲酚红有褪色作用，且褪色的程度与碘酸根的量有关，碘定量测定的线性范围为20μg/25mL～50μg/25mL，检出限为6。

To be specific,its generalized characteristic polynomial has positive double roots,which we proved further has only a double,root by using the affine transformation and inverse affine transformation.

为了更好地进行干涉判断，根据椭圆-椭圆外切的代数条件——广义特征多项式具有正的重根，以及进一步证明出的该正重根的唯一性结论，利用仿射变换和逆变换方法，推导出了椭圆-椭圆的不适合边界解析方程。

Moutan has two different reproduction ways:obligate seed reproduction and amphitrophic reproduction;the dormitory of its embryo has two stages of epicotyl and hypocotyl;the dormitory could be end if it is treated with two temperature conditions.

Moutan生殖特性，具有根状茎、块根、根出条多种形式的以营养繁殖为主、种子繁殖为辅和专性种子有性生殖的两种类型；胚具有上胚轴、下胚轴两段休眠特性，打破休眠需按一定的程序和两种不同的温度条件；……。

In this paper, the number of rhizosphere and non-rhizosphere microbial organisms of fusarium wilt resistant and susceptible watermelon under soil culture and soilless substrate culture were was studied by traditional culture methods.

本文通过传统微生物培养方法，研究了在土培和基质培条件下，抗感枯萎病西瓜不同生育期根际和非根际微生物数量的变化。

It showed that the halophile of Kenyu7 were better than Wuming-5;(2)the contents of proline of the two Zea mays varieties increased significantly,and under high NaCl stress(150mmol/L NaCl or above) the increasing amount of the contents of proline of Kenyu7 was higher than Wuming-5 ,so it showed that the injuries of Wuming-5 imposed by NaCl stress was greater than Kenyu7;(3)the activities of CAT of the two varieties were no obviously changed,while the activities of CAT of Wuming-5 were all higher than Kenyu7 under all concentrations of NaCl solution,which hadn't showed the correlation between the activity of CAT and salinity tolerance.

结果表明，随NaCl溶液浓度的增加：（1）两品种玉米生长均受到严重抑制，发芽势降低，芽和根的长度均呈减小的趋势，总体来看，杂交种垦玉7的发芽势、芽和根的长势均好于自交系无名-5；（2）两品种玉米体内Pro含量均增加，且在NaCl浓度超过150mmol/L时，杂交种垦玉7体内Pro含量增加的幅度明显大于自交系无名-5，而使垦玉7对盐的适应能力强于无名-5；（3）两品种的CAT活性变化幅度均不大，但无名-5的CAT活性在各NaCl浓度条件下均高于垦玉7，这可能是由品种间本身差异造成的，而与品种的耐盐性无直接关系。

It employs carbon dioxide as carbon source to replace traditional sugar, the concentration is controlled to be 2000- 3000ppm, takes light transmission, ventilating and water- proof fluoroethylene resin film as container, and gets tissue culture sprout and replanting sprout of chrysanthemum, which are characterized by largest plant height, largest leaf number, root number, longest root length and largest dry net weight of haulm and root, high rate of emergence and little pollution rate.

本发明提供了一种无糖培养菊花的方法，采用二氧化碳作为碳源，替代传统的糖，控制释放浓度为2000～3000ppm，采用透光性好、透气不透水的氟乙烯树脂膜为容器，在此种培养条件下，不同品种的菊花组培苗和组培后移栽苗在株高、叶数、根数、最大根长、茎叶部分和根部部分的干鲜重最大，出苗率高，污染率最低。

In the paper, the discussion is based on the vowelharmony of the retracted tongue root in Orochonlanguage and the Optimality theory. It is proposed thatthe transparency in the system of retracted tongue rootneuter vowel harmony can be explained with the mutualrelationship between the faithful restrained conditionsand the simultaneous restrained conditions of markedfeatures based on the relationship of sound mechanism.
