متن کاملAspects of clock resetting in flowering of xanthium.
Flowering is induced in Xanthium strumarium by a single dark period exceeding about 8.3 hours in length (the critical night). To study the mechanism which measures this dark period, plants were placed in growth chambers for about 2 days under constant light and temperature, given a phasing dark period terminated by an intervening light period (1 min to several hrs in duration), and finally a te...
متن کاملInhibition of Flowering in Xanthium pensylvanicum Walln. by Ethylene.
Bonner and Thurlow (3) reported that indoleacetic acid (IAA) inhibited the formation of flowers in cockleburs (Xanthium pensylvanicum Walln.) when it was applied as a spray during the long inductive night. In this report, evidence is presented that ethylene also inhibits the flowering of cocklebur plants that have been exposed to a long inductive photoperiod and that the IAA effect is probably ...
متن کاملParticipation of Long-Day Inhibition in Flowering of Xanthium strumarium L.
Two basic experiments defined a long-day inhibitory effect on Xanthium flowering: the basal half of a single leaf on long day inhibits response of the tip half to a short day; and a long-day leaf inhibits response of a short-day leaf, providing it is between the short-day leaf and a receptive bud (whether above or below the short-day leaf). Five hypotheses were explored with the conclusions tha...
متن کاملFlowering in Xanthium strumarium: INITIATION AND DEVELOPMENT OF FEMALE INFLORESCENCE AND SEX EXPRESSION.
Vegetative plants of Xanthium strumarium L. grown in long days were induced to flower by exposure to one or several 16-hour dark periods. The distribution of male and female inflorescences on the flowering shoot was described, and a scoring system was designed to assess the development of the female inflorescences. The time of movement of the floral stimulus out of the induced leaf and the timi...
