    Determination the effect of defoliation timing on cotton yield and quality
    (2007) Karademir E.; Karademir C.; Basbag S.
    This study was carried out for determining the effect of different application times at 40, 50, 60 and 70 % boll opening and untreated plot of the defoliant on cotton yield, earliness and technological properties in Southeast Anatolia Region conditions in Turkey. Maras 92 cotton variety was used as plant material in the experiment field of the Southeast Anatolia Agricultural Research Institute during 2000-2001. Defoliant was including thidiazuron + diuron chemical substance. The result of this study showed that ginning percentage, 100 seed weight, seed germination percentage, fiber fineness, fiber length, fiber strength, reflectance, elongation and seed cotton yield were not affected by the treatment; plant height and first picking percentage in 2001, fiber uniformity in 2000 were 5 % significantly affected. This study showed that application of defoliant didn't affect significantly yield and technological properties of cotton and after 40 % boll opening the defoliant can be used.

    The effects of high temperature stress on some agronomic characters in cotton
    (Pakistan Botanical Society, 2017) Ekinci R.; Basbağ S.; Karademir E.; Karademir Ç.
    High temperature is one of the abiotic stress causing morphological, physiological, biochemical and molecular changes on plant growth and productivity. One hundred and sixty cotton genotypes obtained from genetic stocks was evaluated for high temperature tolerance based on some agronomic characters under field and controlled conditions. Genotypes showed differences for all investigated characters. Plant height, node number and HNR ranged from 68.38-136.45 cm, 18.22-30.10 number.plant-1, 2.89-6.31 (HNR) respectively. Maximum and minimum values in terms of number of sympodial branches, boll abscission at first position, number of seed and seed-cotton yield changed from 11.09-24.42 number.plant-1; 4.17%-20.80%; 20.39-44.11 number.boll-1 and 5.74-60.30 gr.plant-1 respectively. Differences among genotypes were statistically significant for all characters under high temperature stress conditions. High temperature stress was declined the cotton plant development, the decline are important for cotton breeders and cotton breeding programs on the genotypes less affected from high temperature. © 2017, Pakistan Botanical Society.
