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

In seed technology, the use of biocompatible materials, such as chitosan, has been demonstrated to improve the germination process and establishment of seedlings. This research is focused on the effect of a chitosan coating on the germination and development of sesame and bean plantlets. The seeds w...

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