您要查找的是不是：
- 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。
- 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。
- 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。
- 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；
- 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。
- 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。
- High ability of spikelet formation of short-duration varieties could be attributable to high nitrogen content in leaf sheath at panicle initiation stage. 可将小日月品种小穗形成能力高归因于小穗分化初期叶鞘中的氮含量高。
- The floret number was significantly correlated with the weights of leaf, leaf sheath, whole main stem or tiller, and leaf area, but not with the length of stem. 孕穗期小花数均与叶面积、叶片重、叶鞘重和总干物重呈显著或极显著正相关，而与茎高的相关不显著。
- Culms densely retrorsely pubescent in upper part (exserted from leaf sheath) and at nodes; leaf sheath retrorsely pubescent, especially proximally; spikelets with 4 or 5 florets. 浓密的秆反曲的短柔毛在上半部分(从叶鞘外露)和在节上；叶鞘反曲的短柔毛，特别下部；小穗具4或5小花。
- The ultra-structure of the cuticle and distribution of the mineral elements in the cuticle of the leaf and leaf sheath of the rice straw were studied by means of SEM-EDXA. 叶片有发达的叶脉系统;中脉中存在巨大的空腔;中脉的外周交替分布着中型和小型维管束;中脉内部细胞的结点上也存在着维管束。
- LIFE CYCLE: Overwinter in thatch, behind leaf sheaths, or in stems. 生命周期：在枯草层，叶梢背面或者茎上面越冬。
- Leaf sheaths glabrous or thinly pilose; panicle silvery green. 稀疏的叶鞘无毛的或具柔毛；圆锥花序银色的绿色。
- The positions of feeding and oviposition were shifted gradually from the bottom to upper of leaf sheath, and then to leaf blade with the reduction of nitrogen content in host plants. 随着稻株含氮量的下降褐飞虱取食和产卵的位置从叶鞘底部逐渐向上部转移，直至叶片中脉。
- The leaves were consisted of leaf sheath and laminae.The laminae were flat and strip shaped with parallel venation. 圆囊苔草叶基生，由叶鞘和叶片两部分组成，叶片扁平带状，平行脉序；
- Leaf sheaths and stems of 0ryza alta were used as experimental materials. 本实验以高秆野生稻的幼嫩叶鞘和茎为材料。
- Scape 20--30 cm, terete, smooth, covered with leaf sheaths only at base. 花葶20-30厘米，圆柱状，光滑，被叶鞘覆盖只在基部。
