petiole 7-23 mm long, smaller than the rachis; 1 extrafloral nectary, green-vinaceous, sessile, pyramidal, 1-3 mm long, located on the rachis, between the proximal pair of leaflets; rachis 13-15 mm long; leaflets discolorous, 2 pairs, semisucculent, adaxial surface pilose, abaxial surface tomentose, obovate to elliptic, 21-88 X 9-41 mm, apex rounded, base assimetric, venation penninervous, midrib excentric.
Direct shoot regeneration was established from leaf, petiole and nodal explants from in vitro and field grown plants of Solanum nigrum on Murashige and Skoog (MS), and Gamborg's (B5) media containing different levels of plant growth regulator, Thidiazuron (TDZ).
For the leaves, the leaf attitude, color of young and fully mature leaves (CYL and CFL), fragrance strength, leaf blade shape (LBS), leaf blade length (LBL), leaf blade width (LBW), petiole length, leaf apex shape (LAS), leaf base shape, leaf margin type, leaf texture, pelvinus thickness, leaf pubescence, angle of secondary veins to midrib and presence of secondary veins were evaluated (Table 2).
This study was conducted to investigate the feasibility of using the leaf and petiole explants from the field plants for direct organogenesis of plant tissues.
Leaf analysis reveals what minerals and micronutrients have been used by the plant, while petiole analysis reports on what will be available to the plant during the next one to three weeks.
Harvest was performed at 85 days after transplantation, when the following variables were measured: number of leaves, mean leaf length and width, length and diameter of the leaf petiole and total and commercial yield.

the richness and abundance of herbivore and predator arthropods and insect borers are positively influenced by dry leaf size and petiole length, respectively; since the largest physical structure of largest dry leaves and petioles probably determine a greater availability of resources, space for herbivores and predators and food for insect borers.
