1 A sessile leaf has no petiole.

无柄的叶没有叶柄。

2 The stalk that extends from the stem to the base of the leaf is the petiole.

3 Leaves.—Ovate or oblong; three- to five-nerved at base; narrowed into a short petiole.

4 The sensed leaf spectral data are analyzed by a machine-learning algorithm — trained on historical data — to estimate petiole nutrients with near real-time results.

5 Leaves.—With petioles somewhat widened at base and ciliate; the upper all opposite.

6 They not only know that leaves are good to eat, but they know which is the "petiole" and which is the "base."

7 There are 5~8 vascular bundles arranged in arch shape. Secretory cavities are present in the ground tissue of petiole.

叶柄的基本组织中具有裂生分泌腔，5~8束维管束呈弧形排列或散布在薄壁组织中；

8 Our marriage had become like a leaf eaten away by caterpillars, where the petiole and midrib remain with some ghostly connective tracery in between.

9 Also, leaves in most flowering plants attach to the stem through a base called a petiole.

10 Some leaves are attached to the plant stem by a petiole.

12 Botanists have discovered that money is not only the root of all evil, but also its hypocotyl, petiole and axillary bud.

13 The distal ends of these girdles give off several branches, which traverse the petiole and rachis as numerous collateral bundles.

14 The petiole of the fourth leaf — the stalk that attaches it to the plant stem — from the top is identified as ideal.

15 The percentage increase of blade NRA after cultivated by extra-source nitrate was positively related to the petiole nitrate-N concentration.

加入外源硝态氮培养后叶片硝酸还原酶活性的增加程度与叶柄硝态氮含量相一致。

16 The petiole attaches the leaf to the trunk and funnels water through a split in its base.

17 Green or brown flexible petiole, variable internode length. Large trailer.

绿色或咖啡色的柔软叶柄, 节间距离易变. 大的悬垂型.

18 Bud color is light red when the petiole is purple green.

叶柄为乌绿色时，芽为淡红色。

19 Auriculate leaf, one having small appended leaves or lobes on each side of its petiole or base.
