Rich bottom shape, good quality, glossy dark green leaf, thick wider petiole.
Research on the petiole static and dynamic characteristics of the high-efficiency and energy-saving mine explosion-proof fan
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.
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.
Green or brown flexible petiole, variable internode length. Large trailer.
The petiole and the stem all posses assimilation, but con-tain very littls mechanical tissue.
This experiment inspected the effect of four different growth regulators on callus induction of cotyledon young leaf petiole and hypocotyl in creeping dichondra with the orthogonal design.
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.
Adventitious bud regeneration from leaf and petiole of "Cabernet Sauvignon"
Dark green, pointed, heart-shaped, tends to spoon, thick, quilted, glossy, slightly serrated, long red-brown petiole/ red back. Large.
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;
Among cotyledon, petiole of cotyledon, hypocotyl, and radicle, hypocotyl has the most responsive explants to2,4- D.
Leaves leathery, oblong, 7-13 cm long, base cuneate, glossy above, glabrous on both surfaces, margin sparsely and obtusely dentate; petiole 1 cm long.
A sessile leaf has no petiole.
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.
There are 5~8 vascular bundles arranged in arch shape. Secretory cavities are present in the ground tissue of petiole.
Small and exquisite plant shape, dark green and winkless leaf, white petiole, good quality.
The petiole length is shorter. (3)The inflorescence growth at the top stem and form a big podtuft . The special plant-types make the …
Having a petiole.
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.
