Abstract
Orchid pollinia storage can promote the cross pollination when the parental lines have different flowering time. Effects of temperature and storage period on pollinia viability percentage of four fragrant Dendrobium species such as Dendrobium scabrilingue Lindl., D. anosmum Lindl., D. parishii Rchb. f. and D. peguanum Lindl., were studied at three temperature levels, 4, 6 and 8 ๐C and fifteen periods, starting from 30-days interval untill 450 days. It was found that pollinia of the four fragrant species kept at 4 ๐C had significantly viability percentages greater than those kept at 6 and 8 ๐C. Keeping pollinia of D. scabrilingue and D. anosmum, D. parishii and D. peguanum at 4 ๐C could be kept for 240, 240, 270 and 210 days, respectively, without significantly losing their viability percentages.
