Effect of different growth media on number of minitubers and concentration of elements in potato (Solanum tuberosum L) shoot and root

摘要

Potato (Solanum tuberosum L.) is one of the most important economical vegetable. Minitubers are small seed tubers without pathogens that are produced from invitro plantlets after translocation to greenhouse and create healthy and high quality seed tubers. Hydroponic systems increase the production of virus-free potato minitubers. This research was carried out to study the effect of different growth media on number of minitubers and concentration of elements in potato shoot and root and also to compare the hydroponic culture and soil containing media in a randomized complete blocks design with 8 treatments and 4 replications. The treatments consisted of: 1) perlite, 2) perlite + vermiculite (1:1 v/v), 3) perlite + peat moss (1:1 v/v), 4) perlite + soil (1:1 v/v), 5) perlite + soil + compost (40:30:30), 6) perlite + soil + vermicompost (40:30:30), 7) soil, and 8) perlite + peat moss (control). At the end of growth period, the number of tuber per plant and concentration of elements (N, P, K, Na, and Ca) in roots and shoots were measured. Results of analysis of variance showed that bulk density, particle density, porosity, EC and pH of different growth media were significantly different (P Scientific Publications Commission - Health Ministry Scientific Publications Commission - Science Ministry Yektaweb Company Site Keywords ?????, Academic Journal, Scientific Article, ???? ????? ??, ???? ????? ??, ???? ????? ??, ???? ????? ??, ???? ????? ??, ???? ????? ??, ???? ??
