Thirteen chickpea (Cicer arietinum L.) genotypes, raised in the field, were screened for carbon exchange rate (CER), related leaf characters and dry matter production throughout the season. Seasonal pattern of the CER and related characters were similar in all genotypes. CER showed two peaks, one at the late vegetative phase and the other at the peak pod filling phase. Stomatal resistance (rs) and specific leaf mass (SLM) increased in the successively formed leaves while nitrogen concentration tended to decline, especially in later-formed leaves. Nitrogen (N) content per unit area, however, remained relatively constant throughout the season. Significant genotypic variabilities were observed in CER and related characters as well as in total dry matter accumulated at harvest. Seasonal means of CER ranged from 12.5 in HG 1765B to 18.4 μmol CO2 m-2 s-1 in BG 315, SLM from 5.1 in HG 1765 to 6.5 mg dry weight cm-2 in BG 315, rs from 1.31 in BG 315 to 1.92 s cm-1 in Hyb 16-3, leaf N content from 122.6 in HG 1765B to 172.1 mmol m-2 in BG 315 and total dry matter at final harvest from 9.9 in HG 17658 to 34.9 g plant-1 in K4. Seasonal means of CER were positively correlated with SLM, N content per unit area and final harvest dry matter. Stomatal resistance was negatively correlated with CER and final harvest dry matter. The results indicate that although CER is the best selection criterion for higher dry matter production in chickpea, it is possible to use SLM as an indirect selection criterion for CER in this crop. However, such a selection based on SLM involves the risk of elimination of high N-use efficiency genotypes.

SUMMARYDry matter production and partitioning in old clonal tea bushes pruned and maintained at different heights were investigated. New tissues (leaves, new branches and small roots) consti- tuted a small fraction of the total dry matter in all bushes pruned and initially maintained at 70, 40, 25 and 10 cm high, 36 months after pruning. Leaf/frame dry matter ratio was larger and the shoot/root and frame/root ratios were smaller in the bushes initially maintained at 10 cm than in the bushes maintained at other heights. Yields per unit area of the plucking surface were greatest in the smallest bushes initially maintained at 10 cm in 42 months of recording but on the basis of the available space they were greatest in the large bushes initially maintained at 70 cm.
