Auxin - Gibberellin Interaction in Apical Dominance " 2
Indoleacetic acid and gibberellic acid were added to decapitated lightgrown 'Alaska' pea seedlings as substitutes for the intact apex in the control of apical dotiinance. Of various concentrations and combinations tried, a conrbintation of 1 % indoleacetic acid 1 % gibberellic acid was the most inihibiting to side bud growth. The greatest degree of hormonally induced side bud inhibition was ach...

متن کاملSugar demand, not auxin, is the initial regulator of apical dominance.
For almost a century the plant hormone auxin has been central to theories on apical dominance, whereby the growing shoot tip suppresses the growth of the axillary buds below. According to the classic model, the auxin indole-3-acetic acid is produced in the shoot tip and transported down the stem, where it inhibits bud growth. We report here that the initiation of bud growth after shoot tip loss...
متن کاملThe ‘hydrology’ of leaves: co-ordination of structure and function in temperate woody species
The hydraulic conductance of the leaf lamina ( K lamina ) substantially constrains whole-plant water transport, but little is known of its association with leaf structure and function. K lamina was measured for sun and shade leaves of six woody temperate species growing in moist soil, and tested for correlation with the prevailing leaf irradiance, and with 22 other leaf traits. K lamina varied ...
متن کاملWoody species diversity in temperate Andean forests: The need for new conservation strategies
Chile has more than half of the temperate forests in the southern hemisphere. These have been included among the most threatened eco-regions in the world, because of the high degree of endemism and presence of monotypic genera. In this study, we develop empirical models to investigate present and future spatial patterns of woody species richness in temperate forests in south-central Chile. Our ...
