The influence of bulb harvest dates, temperature treatments and growth substances on the ontogeny of Lilium longiflorum






Acta Horticulturae (47): 225-233

The influence of bulb harvest dates, temperature treatments and growth substances on the ontogeny of Lilium longiflorum

The influence on lily growth of 10 deg , 15.5 deg or 21 deg C pre-treatments for 2 weeks was dependent on harvest date and whether the bulbs were later not cooled or cooled for 6 weeks at 4.5 deg. Shoot emergence from non-cooled bulbs was increased by vacuum infusion or injections of GA3, whereas ABA delayed emergence. Neither GA3 nor ABA infusions influenced the flowering rate. Injections of GA3 or GA7 enhanced flowering of cooled bulbs, and GA3, GA4 or GA7 increased stem elongation.
