Title

PREDICTING BRANCHING AND LEAF APPEARANCE AND SENESCENCE IN CHICKPEA VAR. HASHEM

Pages

  39-48

Abstract

 This experiment was conducted to detennine the effects of temperature and photoperiod (day length) and various planting densities on BRANCHING and leaf appearance and senescence in CHICKPEA (Cicer arientinum L.) var. Hashem. The experiment was carried out at Agricultural Research Station of Gonbad, Iran in 2002 in a Randomized Complete Block Design in a split plot arrangement with four replications. Main plots consisted of three planting dates (5 December, 20 January and 5 March). Four planting densities of 16, 32, 48 and 65 plants per square meters were designated as subplots. The results revealed that node (leaf) appearance on the main stem begins at 6.7 Biological Days (BD) after planting and continues at the rate of 1 node day-1 but no further leaves were produced after 35 BD when main stems had approximately 28.5 nodes. Leaf senescence on the main stem commenced after 16 to 20 BD and it continued at 0.65 leaf BD-1 until all leaves on the main stem died Appearance of leaves on the plant consisted of two phases and they were closely related to the node appearance. At the first phase, 2.9 leaves were added to the whole plant leaves with each increase in node on the main stem. The second phase started when there were fourteen nodes on the main stem. At this phase, 8 to 15 leaves were added to the leaves of the whole plant with each increase in node on the main stem. Leaf deaths on whole plant were closely related to leaf senescence on the main stem, and it had two phases. With each percent of leaves death on the main stem 0.5 and 2 percent of whole plant leaves died at first and second phases, respectively. Mean LEAF LIFE was about 23 BD. The results suggest that leaf and branch appearance and senescence in CHICKPEA could be quantified using different equations.
