چکیده
this study was conducted to evaluate different nutrient solutions effects on agria potato mini-tubers production under aeroponic system. the experiment was conducted in the laboratory and greenhouse of ardabil sabalan behparvar company in 2013. four recommended nutrient solutions including: lommen and struik (1992), kang and han (2005), otazu (2010) and hoagland and arnon (1950) were used in a randomized complete block design with three replications. some important traits such as: plant height, no. of main stem per plant, no. of mini-tubers and mini-tubers weight per m2, mini-tubers weight mean and mini-tubers storage conditions were measured and recorded during the growth period and after harvesting time. results of anova showed that nutrient solutions were significant on mini- tubers numbers and mini-tubers weight per m2, and plant height. maximum mini-tubers weight per m2 (11074 g), mini-tuber weight mean (8.64 g) and plant height (87 cm) were observed in lommen and struik nutrient solution respectively. the highest number of mini-tubers (1600 per m2) was achieved from 20 plantlets per m2 (80 mini-tubers per plant), it was more than the conventional system, with peat moss bed and 100 plantlets per m2,that produce about 200 mini-tubers per m2 (2 mini-tubers per plant).
