    Characteristics of coconut oil blended with sunflower oil and mustard oil
    (2009) Madhavan, K.; Naresh Kumar, S.; Mathew, A.C.; John George
    The studies suggested that balanced oil can be formed by suitably blending CNO with other PUFA or MUFA oils so that it can contain all essential components required for the human health.

    Comparative performance of released cultivars and hybrids of coconut for dry matter production and yield
    (2007-02-08) Kasturi Bai, K.V.; John George
    Coconut cultlvars and hybrids viz., West Coast Tall, Chandra kalpa, Pratap, Keraganga, Chandra sankara, takshaganga and Chandralaksha were evaluated tor leaf traits, dry matter production and yield to identify the superior cultlvar among the released ones. The cultivars and hybrid showed significant differences in the above parameters. Based on the results, the traits for higher dry matter production and yield have been delineated. v Among the cultlvars and hybrids the performance of Keraganga (WCTxCBGD) and lakshaganga (LCTxCBCD) f was found to be better than the others in terms of leaf traits, dry matter production and yield. The observations clearly indicated that total nut production per se is not an important criteria for crop improvement programmes, but harvest index (HI) which gives an indication of the partitioning of total dry matter (TDM) towards the economic yield (l.e,copra outum) is the important trait for improving the production potential of the palms. Since the determination of TDM in coconut is very tedious and time consuming, partitioning of total nut dry matter towards copra can be used as an important trait for crop improvement programmes.

    Stress responsive proteins in coconut seedlings subjected to water, high-light, flooding and high-temperature stresses
    (2007-12) Naresh Kumar, S.; Kasturi Bai, K.V.; John George; Balakrishnan, A.; Siju Thomas, T.
    Coconut seedlings of different cultivars and cross combinations were subjected to stresses like water, high temperature and flooding stresses independently. Results indicated increase in the concentration of heat stable protein fraction (HSPF) in leaf tissue even when the total protein concentration reduced due to stress. The percentage of HSPF in leaf tissue increased with decrease in leaf water potentials. Quantitative changes in proteins also we& observed in leaf and root tissue due to temperature and flooding. In HSPF, proteins of -66KDa are found in root and leaf tissue. Leaflet tissues have specific in the range ~10 and ~14 KDa which are not present in the root tissues. Two extra proteins 66 KDa and ~76 KDa appeared in water stressed WCT seedlings. They were also present in seedlings exposed to high light intensity (~1,500 mmol/m2/S) apart from an extra LMW HSP of 14.4 KDa. Among the MMW- proteins, protein of 53 KDa is present in all WCT samples. The LMW protein of 20.1 KDa, present in non-stress seedlings disappeared during water stress period. In temperature induced and flooded leaflet tissue, new proteins (LMW range ~17 KDa) were observed. In temperature induced root tissue, a protein band in the range of 30 KDa was observed but not in flooded root or in control root. Results indicate quantitative and qualitative variations in stress proteins in coconut seedlings subjected to different abiotic stresses.
