A small modified leaf, especially a colourless membranous one, such as on a rhizome or forming part of a bulb.
〔植〕鳞叶
Example sentencesExamples
Later, when trees reach the adult stage, leaf primordia differentiate into scale leaves, and photosynthetic activity is shifted to long needles differentiated on short shoots.
On reaching the top of a tree, the growing point descends, progressively changing its morphology and leaf structure, and eventually assuming a very thin filiform shape with only scale leaves on the soil.
Each GU can be identified by the existence of morphological markers in the form of scale leaf and assimilating leaf scars alternately distributed along the aerial axes.
For example, a scale leaf that is able to support greater rates of water loss may have a higher total productivity than a much larger leaf that requires high surface resistances.
The scale leaves are under the tunic and hold all the nutrients needed to grow the cultivar.
