您要查找的是不是:
- Chlorophyll a/b ratio of the ear leaf waslowest,sequentially,of the terminal leaf,and of the fifth leaf. 但其叶绿素 a/b 值却是果穗叶最低,顶生叶居中,第5叶最高。
- A decrease of source-sink ratio prompted a decrease in SOD activity,POD activity and soluble protein content in ear leaf, the reason of which maybe defoliation caused leaf hurt. 高油玉米果穗叶的 SOD、POD、PEP 羧化酶等酶活性及可溶性蛋白质含量,随源/库比的减小而降低,叶片的光合速率、光合色素含量等随源/库比的减小而显著增加,且增幅大于普通玉米。
- Leaf blades of low leaf position except the base leaf and high leaf position had more leaf pulp cell with lower annulation number and less leaf pulp cell with higher annulation number,ear leaf had higher ratio leaf pulp cell with over six annulations. 就叶片内叶肉细胞环数而言,低叶位和高叶位的叶片低环数的叶肉细胞比例相对较高,而高环数的叶肉细胞比例较低,果穗叶层六环以上的叶肉细胞比例较高;
- To sum up these data,we see that tendencies of changes betweenstructure and function of leaf blades of different levels are uniform. The structure and function of ear leaf are better than that of otherleaves. 综上所述,玉米不同叶位叶片的结构与功能的变化趋势是一致的,中部果穗叶片优于其它叶位。
- The distribution of 14C-assimilates in plant organs and different positions of ear in maize (Zea mayo L.) was studied by feeding the ear leaf with 14CO2 at early period of kernel development. 摘要通过14C示踪方法,研究了在籽粒发育前期饲喂果穗叶后14C-同化物在植株及果穗不同部位的分布。
- The distribution of 14C-assimilates in plant organs and different positions of ear in maize (Zea mays L.) was studied by feeding the ear leaf with 14CO2 at early period of kernel development. 通过14C示踪方法,研究了在籽粒发育前期饲喂果穗叶后14C-同化物在植株及果穗不同部位的分布。
- The ear leaf is larger number of vascularbundle,the width of vessels,the content of chlorophyll and the photo-synthetic rate as compared with other leaves. 在维管束的数目、导管粗度、叶绿素的含量和光合强度诸方面,果穗叶均高于其它叶位。

- Under high temperture and low irradiance in summer, the photosynthetic capacity of ear leaves for Yayu 2 and that of Chengdan 202 were raised by 40mg/kg and 10mg/kg S-3307 treatment, respectively. 40mg/kg和10mg/kg的烯效唑处理分别显著提高了雅玉2号和成单202夏季中午高温弱光下穗位叶的光合能力。
