摘要：

The objective of this study was to determine effects of bulb size on production time and factors influencing crop quality in pineapple lily (Eucomis sp.) cultivars developed originally for cut flower production. The percentage of bulbs producing an inflorescence increased as bulb size increased. One hundred percent of bulbs >18 cm circumference flowered in three of the four cultivars whereas 'Tugela Jade' exhibited 88% flowering. The number of flowers per inflorescence increased as bulb size increased. Scape length increased as bulb size increased in 'Reuben'. Inflorescence length increased as bulb size increased in 'Reuben', 'Tugela Jade', and 'Tugela Gem'. Days to anthesis from planting decreased as bulb size increased in 'Reuben' and 'Tugela Jade'. For all cultivars, the largest bulbs produced the greatest number of leaves per plant and the highest quality inflorescences, largely attributable to the larger number of flowers produced per inflorescence compared with smaller bulbs.
