Germination Performance of Campo Grande (Stylosanthes capitata / macrocephala) Stylers Seeds Coated with Different Layers of Inert Material
Journal Title: Journal of Experimental Agriculture International - Year 2017, Vol 18, Issue 4
Abstract
The coating is based on the deposition of inert material in successive layers that allow the modification of the physical characteristics of the seeds. However, this procedure can compromise the physiological characteristics. In this sense, Stylosanthes capitata / macrocephala cv. Campo Grande seeds were coated with sand of less than 0.25 mm with different layers with the following treatments: TR1- Seeds not covered and scarified (SNCS); TR2 - 6 layers (150 g); TR3 - 8 layers (200 g); TR4 - 10 layers (250 g); TR5 - 12 layers (300 g); TR6 - 14 layers (350 g) and TR7 - Seeds not covered and not scarred (SNC and NS), to study the effect of the coating with different layers on the physical and physiological characteristics of these seeds. Polyvinyl glue (PVA) was used as a cementitious material. The coating was done in a bench drawer. The tests were arranged in a germitest* roll paper. The experimental design was a completely randomized, in the laboratory and randomized blocks in a greenhouse with 6 treatments containing four repetitions of 50 seeds in four blocks. The 12-layer sand coating benefited the physical characteristics and did not compromise the physiological characteristics of the seeds and the development of the Estilosantes Campo Grande seedlings.
