Response of Chickpea to Photoperiod as a Qualitative Long-day Plant

A. Soltani, B. Torabi , E. Zeinali and R. Sarparast

Abstract:
Chickpea (Cicer arietinum L.) is considered to have a quantitative long-day response to photoperiod. No day-neutrality or qualitative response to photoperiod has been reported. The objective of this study was to report qualitative response of chickpea to photoperiod. Four chickpea genotypes from different geographical areas of Iran were serially sown in 11 sowing dates during 2001 to 2003. Plants sown on August, September, October, November and January sowing dates flowered at about May 10 (day of year 130). Flowering was delayed up to 120-150 days when day length decreased to about 11-12 h, indicating that plants remained unresponsive until photoperiod increased above the critical value. It was concluded that chickpea can also be classified as a qualitative long-day plant.
