您要查找的是不是：
- The stoma density of diploid is thicher than spur type. 二倍体气孔密度大于三倍体,普通型大于短枝型。
- The soil water stress leads to the increase in stoma density. 水分胁迫使气孔密度增加；
- It is incorrect that only stoma density and stomatic chamber size are used as xerophilous indexes. 单纯地把气孔密度、气室大小作为抗旱指标是不正确的。
- In the stoma density concerned, cold resistance of Guangming No.13,Miyamoto,Taitian C. 结果表明,气孔密度比较宫本、光明13号、太田柑、大浦抗寒性较强;
- With CO2 concentration enrichment, the leaf stoma density becomes small for C3 crops, but it shows the opposite tendency for C4 crops (maize). 随着CO2浓度升高，C3作物叶片气孔密度变小，C4作物(玉米)呈相反趋势；
- The results showed that the ploidy level had a significantly positive correlation with the stoma diameter, but a negtive correlation with the stoma density. 结果表明，红掌倍性与气孔长度呈显著正相关，而与气孔密度呈显著负相关。
- The trees with thick cutin layer, high stoma density, thick stockade tissue, high ratio of stockade tissue thickness to sponge tissue thickness, and high sedimentation of leaf tissue structure are of greater drought resistance. 叶片厚度、尤其是角质层的厚度和海绵组织厚度是评价供试含笑抗旱性的重要解剖指标。
- The result showed that sea buckthorn from China had a relatively smaller leaf area,more layers of epidermic hairs and a larger stomata density than sea buckthorn from Russia. 结果表明,抗旱性强的中国沙棘叶片小,表皮毛层数多,气孔小,气孔密度大;
- The differences of stomata characters between the conventional rice and hybrid rice were compared and analyzed by the relativities among stomata density, length and width. 结果表明，气孔密度变幅大于气孔长度与宽度；
- The result shows the difference in stomata density between tissue-cultured "Junzao" and original seedling is minimum of three species of jujube, but the difference of "Goutouzao" is maximum. 研究表明：三种枣树中骏枣组培苗的气孔密度与原种苗的气孔密度差异最小，狗头枣的差异最大；
- The changes of water-use efficiency and stoma density of Leymus chinensis along Northeast China Transect 中国东北样带关键种羊草水分利用效率与气孔密度
- The Relationship between the Stoma Density of Eggplant Leaves and Their Resistance to Polyphagotarsonemus latus 茄子叶片气孔密度与侧多食跗线螨发生数量的关系
- The density of population in this city is very high. 这个城市的人口密度非常高。
- Stoma density 气孔
- 9 QTL were found of Stoma density and most of them were additive effect QTLs, and 4 had a general contribution over 10%,such as RM1183-RM1152, RM1244-RM1297 in chr1. contribution was 10.95%,13.17% respectively. 气孔密度共定位到9个QTL位点，以加性效应为主； 气孔长度共定位到16个QTL位点，其中有4个QTL位点贡献率较大，单个位点贡献率超过10%25，如：1号染色体RM1183-RM1152、RM1244-RM1297，分别为10.;95%25，13
- The nectar was secreted by stoma and epidermls. 蜜汁通过气孔和表皮细胞泌出。
- The area had a population density of five people per square mile. 该地区人口密度为每平方英里五人。
- And the number of stoma increased. 叶绿休的数量减少，而气孔的数量增加。
- The density goes down exponentially with height. 分子密度随着高度的上升而指数衰减。
- The population density is evened out. 种群密度亦趋于均匀化。
