1、Having a petiole.

2、A sessile leaf has no petiole.

3、Leaf blade had more proportion than petiole in fresh weight.

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

5、Light green, elliptical, very thin, long flexible petiole.

6、The two genes didn't expressed in the leaf and petiole.

7、Small and exquisite plant shape, dark green and winkless leaf, white petiole, good quality.

8、Dark green and glossy leaf, thick and white petiole, good plant shape, heat tolerance, good quality.

9、And Chlorogenic acid played an important part in resisting petiole spot of Chinese cabbage.

10、Thick, white and long petiole, dark green leaf, vigorous growth, heat tolerance.

11、The nitrate content of Chinese cabbage organ was: petiole (stem)> leaves> root.

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

13、Dark green, pointed, heart-shaped, tends to spoon, thick, quilted, glossy, slightly serrated, long red-brown petiole/ red back. Large.

14、A typical foliage leaf of a plant belonging to the dicotyledons is composed of two principal parts: blade and petiole.

15、The petiole length is shorter. (3)The inflorescence growth at the top stem and form a big podtuft . The special plant-types make the …

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

17、The paper studied effects of GA_3 and IAA on cellulase activity in abscission zone from petiole of primary leaves of bean, cotyledon petioles and boll petioles of cotton.

18、Result and Conclusion: By stress time increasing, the content of MDA in lamina and petiole increased obviously, but it increased invisibly in tuber.

19、Leaves crowded on upper part of branches, oblanceolate, 4-5.5 cm long, 1.5-2 cm wide, apex acute and mucronate, base attenuate, margin slightly revolute, obscurely glaucous beneath; petiole 0.5-1 cm long.

20、The soybean variety under-sowing with maize ought to select that the leaf is middle size, lanceolate or elliptic, deep green colour, and the petiole is short and thick;

21、In long shoot, the leaf width, leaf length, leaf area, petiole length and basal Angle decreased, but the leaf index and the ratio of lobation increased as its arrangement increased.

22、Ball is short and round, good embraces of leaves, the outside leaf is green and wrinkle, light green in petiole, the single ball is 7-8 kg, Resistant to mildewed, soft , virus disease, bear the hoarding, the quality is good.

23、Leaves thick leathery, obovate-lanceolate, obovate or oblong-lanceolate, 4-12 cm long and 2-3.5 cm wide, apex rounded, sometimes emarginated, base cuneate, abaxial surface thinly covered with a grayish to fawn indumentum at first, later glabrescent; petiole 1-1.5 cm long, glabrescent.
