1. The leaf-stalks grow opposite from the stem.

2. The leaf-stalk is thickened with air-filled tissues inside for buoyancy of the plant.

3. Description: The leaves are long, lanceolate, light to bright green, borne on short leaf-stalks.

4. The nitrate contents in leafstalk were higher than that in laminae and fruit.

5. Establishment of Regeneration System from Leaves and Leafstalk of Spiraea prunifolia Sieb . et Zucc.

6. Individual fruit mass was an important constituent character of yield, while leafstalk length and node length were two important constituent characters of fruit length.

7. The lamina regeneration ability of Akihime and Toyonoka were better than that of their leafstalk.

8. We genetic transformation of ACO antisense gene into lily's bulb and leafstalk by Agrobacterium tumefaciens - mediated method./leafstalk.html

9. North-Chaihu's stem tufts or grows single, there isn't any fabric leafstalk, and the remnant is purple red.

10. Objective: To develop a HPLC method for the determination of Aristdohic acid contents in the radix, leafstalk and leaf of Asarum.

11. METHODS We used scan electron microscope to study tengcha' s leaf and leafstalk that were the main medicinal parts.

12. The results showed that the nitrate content in laminae and leafstalk increased following the increase of nitrogen, while that in fruit first increased and later decreased.

13. The results showed that the adventitious shoot inducing rate of leafstalk was higher than leaf and stem, the adventitious shoots polarization of stem cambium was also good.
