Partitioning and Utilization of Carbon and Nitrogen for Dry Matter and Protein Production in Chickpea (Cicer arietinumL.)

Distribution of 14CO2 during ontogeny of chickpea (Cicer arietinum) grown at two moisture levels

“…The leaves and stem retained about 43% of the assimilate in the soluble fraction after 24 h feeding of both control and stressed plants at 120 DAS, showing that translocation of assimilates to different plant parts slowed down as the plant was reaching maturity. Studies of the economy of C and N (Hooda et al, 1986;Hooda, 1987) have also indicated that remobilisation of C and N from the stem and other vegetative parts for seed filling in chickpea is low compared to other crops. Thus considerable potential exists for the increase of the mobilisation of C from different plant parts, particularly the stem.…”

“…The efficiency of remobilisation of early fixed carbon to support the seed requirement in legumes has been reported to be low (Pate & Flinn, 1973;Withers & Forde, 1979;Pate, l985), but in cereals it can be over 50% (Cock & Yoshida, 1972;Bidinger, Musgrave & Fischer, 1977;Aggarwal & Sinha, 1984). Computation of carbon and nitrogen budget of chickpea plant grown under normal (Hooda et al, 1986) and water stress (Hooda, 1987) conditions has indicated a poor efficiency of remobilisation of C and N from vegetative parts to the seeds. To further establish the role of photosynthates produced during different stages of growth in seed dry matter production, I4CO, labelling studies were carried out in chickpea.…”

Irrigation Decreases Loss of Leaf Nitrogen and Rubisco During Pod Development in Chickpea

“…Consistent with this, it was observed that de¯owered plants in which pods were not allowed to develop retained higher leaf N content (Ghildiyal et al 1987, Mitra andGhildiyal 1988). Hooda et al (1990) observed that about 55±58 % of the seed N requirement was met by mobilization from vegetative parts; leaves contributed 39 % of seed N. Rubisco accounts for up to 30 % of leaf protein and could therefore be the major source of N mobilized from the leaves. It has been suggested that, under many types of growth conditions, part of the investment in Rubisco may be viewed as a N store (Stitt andSchulze 1994, Stitt 1996).…”

Effect of nitrogen source and salinity level on salt accumulation of two chickpea genotypes

“…Twenty-six days after sowing the strength of the nutrient solution was doubled. To coincide with peak N-fixation, the experiment was terminated at flowering (Hooda et al, 1986). Root and shoot extracts, obtained by dry ashing, addition of 6 M HC1, evaporation to dryness and then dissolving the ash in 36% HC1 (The Analysis of Agriculture Materials, 1986), were assessed for Na + and K + by fiamephotometery.…”
