Effects on Germination and Plantlet Development of Sesame (Sesamum indicum L.) and Bean (Phaseolus vulgaris L.) Seeds with Chitosan Coatings

In seed technology, the use of biocompatible materials, such as chitosan, has been demonstrated to improve germination process and establishment seedlings. This research is focused on effect a chitosan coating development sesame bean plantlets. The seeds were treated with different techniques combinations chitosan: solutions at 0.1, 0.5 1% used in film coating, flakes particle sizes 1.19 mm 0.71 crusted size for acrylic resin. Images coatings obtained by means scanning electron microscopy; germination, speed, vigor index, length root area plantlets also determined. Chitosan treatments increased 26% 16% compared control; speed index showed an increase 61% 58% sesame. 77%, four times more, control treatments. Different forms seedling establishment; however, response type given stage will depend crop species.
