The existence of a critical period for the abscission and a non-critical period for blasting of flower-buds of Lilium ‘Enchantment’; influence of light and ethylene

Low light intensity and flower bud abortion in Asiatic hybrid lilies. I. Genetic variation among cultivars and progenies of a diallel cross

“…Flower bud abscission seems to be promoted by increased ethylene production by the stamens in the buds as found for 'Enchantment' (DURIEUX et al, 1983). Abscission was found to be promoted by the production of ethylene at the critical stage of development of the buds (DURIEUX et al, 1983). Thus, in male sterile plants abscission will be less than in male fertile plants.…”

“…Flower bud abscission seems to be promoted by increased ethylene production by the stamens in the buds as found for 'Enchantment' (DURIEUX et al, 1983). Male sterility occurs when no functional stamens are developed.…”

“…According to DURIEUX et al (1983) the rate of flower bud abscission depends on the length of time the bulbs had been stored before planting. According to DURIEUX et al (1983) the rate of flower bud abscission depends on the length of time the bulbs had been stored before planting.…”

“…In Liliurn x 'Enchantment' bud blasting can occur throughout the whole period of flower bud development, but abscission only during a critical stage, when a bud is 2 to 3 cm long (KAMERBEEK & DURIEUX, 1971). It seems rather to be related to increased ethylene production by the flower buds at the end of the meiotic process in the stamens (DURIEUX et al, 1983; VAN MEETEREN & DE PROFT, 1982). It seems rather to be related to increased ethylene production by the flower buds at the end of the meiotic process in the stamens (DURIEUX et al, 1983; VAN MEETEREN & DE PROFT, 1982).…”

Plant Hormones under Challenging Environmental Factors

“…It was observed that growth of plants under shade affected the dry matter accumulation at all stages. According to Durieux et al ( 1983 ), a short period with very low light intensity at the critical stage for bud abscission should be suffi cient for a disproportionate increase in percentage of fl ower bud abortion. Within 26-9 °C range of mean maximum temperatures, the expression of the panicles appeared to be a function of the light intensity.…”
