您要查找的是不是：
- Flag leaf sheath 叶鞘
- flag leaf sheath length 旗叶鞘长度
- The leaf sheath enclosing the lowest two internodes should be stiff too. 包裹最低两个茎节的叶鞘也应坚硬。
- In grasses the ligule occurs at the junction of the leaf sheath and lamina. 在禾本科植物中，叶舌生长在叶鞘和叶片的交界处。
- This the first report of cytogenetic study of flag leaf position in common wheat ,Triticum aestivum L. 摘要 本文首次对小麦旗叶姿态进行了比较系统的细胞遗传学研究。
- Culm sheath and leaf sheath auricles subfalcate, short. Leaf blade abaxially not hairy along midrib. 竿箨和叶鞘的叶耳近镰状，短。叶片背面而不是有毛的沿中脉。
- Inflorescence usually a contracted panicle, enclosed in uppermost leaf sheath or shortly exserted, spikelets few. 短在最上部的叶鞘或通常花序收缩圆锥花序，内藏，很少的小穗。
- Even more amazing were the many red ants that had gathered to form a ball encircling the leaf sheath. 更不可思议的是，树上有很多红蚂蚁，都聚集成球，围在叶鞘四周。
- The cultivars that had a high chl (a+b) value,low chl (a/b) value and relatively big Flag Leaf area could be selected in wheat breeding. 小麦育种上应选择生育后期叶绿素 (a +b)较高 ,叶绿素 (a/b)值低 ,且旗叶面积相对较大的品种。
- Inflorescence a short dense head, subtended by an inflated leaf sheath with rudimentary blade. 花序一紧密的短头状花序，以一膨大的叶鞘具不发育叶片被包着。
- There were close correlation in the same SOD, POD, CAT, NR and GS activity, and MDA content between roots and flag leaf. 小麦生长发育后期根系与旗叶超氧化物歧化酶(SOD)、过氧化物酶(POD)和过氧化氢酶(CAT)的活性、丙二醛(MDA)的含量、氮素代谢特性是相互联系、密切相关的；
- Uniconazole treatment decreased the endogeneous IAA and GA3 contents in the whole plant especially in leaf sheath. 烯效唑浸种的玉米幼苗中IAA和GA 3含量下降，叶鞘中尤为明显；
- Effect of irrigation on photosynthesis decline of winter wheat flag leaf during senescence was studied with field plot experiment. 利用田间小区试验研究了不同灌水对冬小麦旗叶光合功能衰退的影响。
- Culm sheath ligule less than 1 mm; leaf sheath ligule less than 1 mm, hirtellous. 竿箨叶舌不到1毫米；叶鞘叶舌不到1毫米，具微糙硬毛。
- The effects of deep cultivation-root cutting on the senescence of flag leaf after anthesis and yield have been studied for dry land wheat production. 在旱地大田条件下研究了深耘断根对旱地高产小麦花后旗叶衰老及产量的影响。
- The role of overirrigation improving photosynthesis decline of flag leaf was mainly at the latter stage and had no role for yield increase. 过量灌水改善旗叶光合衰退的效果主要表现在后期，对产量提高的意义并不大。
- Plastic film mulching markedly increased biomass per a plant,flag leaf area,tillers per unit soil area,grains per ear and 1 000-grain weight. 覆膜显著增加单株生物量、旗叶面积、亩穗数、穗粒数和千粒重。
- Culms densely retrorsely hairy throughout; leaf sheath densely pubescent, leaf blade abaxial surface pubescent; lodicules long narrowly triangular. 浓密反曲有毛的秆全部；密被短柔毛的叶鞘，叶片背面短柔毛；鳞被长狭三角形。
- Then A new classification rule of brown leaf sheath is built for the screening of rice resistant varieties in greenroom. 但如无雄螨，斯氏狭跗线螨可进行孤雌生殖，且后代都是雄螨，因此，其属产雄孤雌生殖。
- Results indicated that the order of net photosynthetic rate of the flag leaf Was: Taishan No.1 (adaptability moderate) >Jinan No.13 (strong) >Changle No.5 (weak) . 结果表明，旗叶的光合速率顺序为: 泰山一号(中度耐肥)>济南13(高度耐肥)>昌乐5号(不耐肥)。
