Different growing substrates affect Periwinkle’s (Catharanthus roseus L.) growth and flowering
Journal Title: Journal of Biodiversity and Environmental Sciences (JBES) - Year 2015, Vol 6, Issue 6
Abstract
Periwinkle (Catharanthus roseus L.) is one of the important ornamental and medicinal plants, due to the presence of the blue tint flowers and the indispensable anti-cancer drugs, vincristine and vinblastine. Therefore, the production of this plant has been emphasized. Nutritional management and application of organic and inorganic materials as substrates can play an important role in increasing the productivity and quality of this plant. Therefore, the effects of different organic materials as growing media including: rotted manure spent mushroom compost (SMC), vermicompost, and garden soli as control on the vegetative growth, yield and flower quality of Periwinkle were considered. The organic materials were in four levels (15, 30, 40 and 50 %). Analysis of variance showed that the effects of different treatments on studied properties are significant (p<0.001). The maximum of plant height (37.83 cm), fresh weight of shoot (116.55 g), number of flower (42.67) and diameter of flower (45.67 mm) were obtained in vermicompost 50%. Moreover, maximum of dry weight of shoot (32.91 g) was observed in SMC 40%. The results showed that the application of vermicompost 50% resulted in significant increases in concentration of N. The maximum of number of leaf were obtained in vermicompost 50%. The application of organic fertilizers resulted in significant increases in concentration of P and K compared to control. In conclusion, the results showed that vermicompost was found to be suitable for production of Periwinkle. This organic matter can be an alternative substrate in growing media.
