palearctic

In my present study , changes in structure and function of all parts of non - leaf organs ( culms , paleae , lemmas , awns , and glumes ) were investigated during a series of developmental stages and in various cultivars . characterization of the culms of lodging - resistant wheat varieties lodging is a potential cause of yield reduction in cereal crops ( crook et al , 1994 ) 其中,比較分析了非葉器官葉綠體超微結構的差異,測量了非葉器官的放氧和低溫熒光等生理指標,嘗試從結構與功能相結合的角度,探討非葉器官在提高作物產量中所起的重要作用。

Each individual floret of the spikelet is also subtended by two bracts , the lower being called the lemma and the upper the palea 每一朵能發育的花的外面又有兩片鱗片狀的薄片包住,稱為稃片,外面的一片稱外稃,是花基部的苞片,里面的一片稱內稃。

In grasses , the lemma , palea , and the flower they enclose 禾本植物的外稃、內稃及它們包被的花。
