Abstract: The experimental design was 4 x 5 factorial with three
replications in fully controlled research greenhouse in Department of
Soil Sciences and Plant Nutrition, Faculty of Agriculture, University
of Selcuk in the year of 2009. Determination of tolerant chickpea
genotypes to drought was made in the research. Additionally,
sophisticated effects of drought on plant growth and development,
biochemical and physical properties or physical defense mechanisms
were presented. According to the results, the primary genotypes were
Ilgın YP (0.0063 g/gh) for leaf water capacity, 22235 70.44(%) for
relative water content, 22159 (82.47%) for real water content,
22159 (5.03 mg/l) for chlorophyll a+b, Ilgın YP (125.89 nmol
H2O2.dak-1/ mg protein-1) for peroxidase, Yunak YP (769.67
unit/ mg protein-1) for superoxide dismutase, Seydişehir YP
(16.74 μg.TA-1) for proline, Gökçe (80.01 nmol H2O2.dak-1/ mg
protein-1) for catalase. Consequently, all the genotypes
increased their enzyme activity depending on the increasing of
drought stress consider with the effects of drought stress on leaf
enzyme activity. Chickpea genotypes are increasing enzyme
activity against to drought stress.
Abstract: This research was conducted to determine responses
of chickpeas to drought in different periods (early period, late period,
no-irrigation, two times irrigation as control). The trial was made in
“Randomized Complete Block Design" with three replications on
2010 and 2011 years in Konya-Turkey. Genotypes were consisted
from 7 lines of ICARDA, 2 certified lines and 1 local population. The
results showed that; as means of years and genotypes, early period
stress showed highest (207.47 kg da-1) seed yield and it was followed
by control (202.33 kg da-1), late period (144.64 kg da-1) and normal
(106.93 kg da-1) stress applications. The genotypes were affected too
much by drought and, the lowest seed was taken from non-irrigated
plots. As the means of years and stress applications, the highest
(196.01 kg da-1) yield was taken from genotype 22255. The reason of
yield variation could be derived from different responses of
genotypes to drought.
