摘要

The effects of substrate (perlite 1-5 mm, peat + perlite in a 1:1 mixture or washed pumice 5-10 mm) irrigated 8 or 16 times/day for 1 min on yield and flower quality of gerbera cultivars Fame, Rosabella and Sunspot were compared during a 6-month growth period with plants grown in soil and drip-irrigated for 10 min/day. Peat + perlite gave better or similar flower yield and quality compared with soil; pumice gave the lowest performance, though still satisfactory. Plant growth and yield were unaffected by irrigation frequency and the high frequency resulted the surplus nutrient solution being lost in drainage. Fame (single yellow) gave the largest yield (5.96-6.20 flowers/plant in peat + perlite) and flower diameter (11.2-12.15 cm), whereas Sunspot(single orange) had the lowest yield (3.42-5.46 flowers) and the longest stems (57.8-70.1 cm).
