Evaluation of the effect of In vitro potato plantlet density effect on their agronomic attributes and their efficiency on mini-tuber production
Journal Title: International Journal of Farming and Allied Sciences - Year 2014, Vol 3, Issue 3
Abstract
Invitro Plantlet characteristics same as leaf area, shoot growth, balanced growth of root and shoot are the main attributes which guarantee subsequent successful growth of plantlet in greenhouse condition. These characteristics will be affected by in vitro conditions such as plantlet density. This study was carried out to evaluate the effects of in vitro potato plantlet density on their agronomic attributes and their efficiency on mini-tuber production under greenhouse conditions. We took advantage of a 2×4 factorial design (two potato varieties namely Agria and Sante, and invitro plantlet density including 2, 4, 6 and 8 single node cutting on 250 cc Erlenmeyer) to evaluate above mentioned objectives. Statistical analysis revealed that there are significant differences between cultivars, in vitro plantlet density and cultivars × in vitro plantlet density interaction effects (p<0.05). Most of the greatest agronomic characters were observed in Sante cultivar which had produced in 8 plantlet density.
