The Quantitative Effects of Temperature and Light on Growth, Development and Yield of Faba Bean (Vicia faba L.) (II. Development)

Abstract

In this study, it was aimed to define the relationships between temperature, light intensity and development stages for faba bean namely rate of progress to emergence, flowering rate, rate of progress to pod onset, rate of height, rate of stem diameter increase and leaf appearance rate. Changes in plant development caused by the effects of environmental conditions such as temperature and light intensity were intended to be described by plant development stages models. All equations produced for development stages were derived as affected by light intensity and temperature. As a result of multi-regression analysis, it was found that there were close relationship between actual and predicted development stages. The regression coefficients (R2) of the produced equations for development stages changed from 0.71 (leaf appearance rate) 0.99 (flowering rate and rate of progress to pod onset). © 2007 Academic Journals.
