Modeling leaf production and senescence in chickpea (Cicer arietinum L.): leaf lifetime

Abstract

Quantitative information regarding leaf lifetime in chickpea (Cicer arietinum L.) is scarce. Data from a field experiment with a range of planting date and density were analyzed to estimate leaf lifetime and its variation in chickpea. The experiment was conducted under well-watered conditions. An average leaf lifetime of 23.5 physiological days was estimated. A physiological day is a calendar day with no limitation of photoperiod and temperature for plant development. Planting date and density did not affect leaf lifetime. The results of this study can be used in simulation models of chickpea.
