Effect of different planting beds on potato mini-tuber production from micro-tuber in greenhouse conditions

摘要

Production of disease-free potato mini-tubers in a controlled environment can be important in enhancing crop yield. This study was designed to investigate potatomini-tuber production from micro-tuber at different potato cultivar and different planting bedin greenhouse conditions based on completely randomized design with three replications. The first factor consisted of potato cultivars : Agria, Savalan, Sante and Spirit and the second factor included planting beds including zeolite, punch, Vintrashtayn peat moss, Vintrashtayn peat moss: zeolite (1:1), Vintrashtayn Peat moos : punch (1:1). In this study, plant height, leaf number, stem diameter, leaf area index, chlorophyll content were evaluated. Results indicated there is significant difference among different planting beds and different cultivar regarding plant height, number of stems per plant, number of leaves per plant and the interaction cultivar vs. planting bed regarding tuber number and mini -tubers weight per square meter at 1% level of probability. The greates plant height was observed in Sante and Peat Moss : zeolite (1:1). The greatest and the least number of leaves per plant was observed at Spirit and Agria, respectively. In addition, among different planting bed the highest and the least number of leaves per plant was observed at peat moss : zeolite (1:1) and pure peat moss
