“…The germination of all seeds begins with the imbibition of water, and after an interval, enzymatic proteins are synthesized and activated. Germination is regulated by hormonal interactions and environmental factors (Paleg 1960, Iglesias andBabiano 1997) and occurs only when conditions become favourable. Many factors, both exogenous and endogenous, affect this process.…”

The present work describes the changes that take place in phytohormone contents in germinating chickpea (Cicer arietinum cv. Aziziye-94) seeds in response to heavy metal stress. For this aim, endogenous abscisic acid (ABA), gibberellic acid (GA 3 ), zeatin (Z) and zeatin riboside (ZR) contents were followed for 24, 48 and 72 h in chickpea seeds germinating at the concentrations of 0.1, 1.0 and 5.0 mM Pb or 0.1, 1.0 and 10 mM Zn. The results showed that Pb and Zn significantly delayed and impeded the germination of chickpea seeds. The negative effect of Pb on germination was higher than that of Zn. Further, Pb increased ABA and Z contents while decreased GA 3 content in the germinating seeds. The high concentrations of Zn (1.0 and 10 mM) decreased contents of Z, ZR and GA 3 while 0.1 mM Zn increased the content of the same hormones. The ABA content was enhanced by Zn in all concentrations used.

“…However, there are a few reports on the effects of these hormones on seed germination. Seed germination is one of the most critical phases of plant life (Misra and Dwivedi, 2004) regulated by hormonal interactions and environmental factors (Paleg, 1960;Iglesias and Babiano, 1997;Atici et al, 2005 Effects of progesterone and β-estradiol on morphologic (germination velocity, root and shoot length) and biochemical (activities of α-amylase, superoxide dismutase, peroxidase and catalase, H 2 O 2 content, lipid peroxidation) parameters during germination and post-germination stages of chickpea seeds were studied. The seeds germinated at various hormone concentrations (10 -4 , 10 -6 , 10 -9 , 10 -12…”

Effects of progesterone and β-estradiol on morphologic (germination velocity, root and shoot length) and biochemical (activities of α-amylase, superoxide dismutase, peroxidase and catalase, H2O2 content, lipid peroxidation) parameters during germination and post-germination stages of chickpea seeds were studied. The seeds germinated at various hormone concentrations (10 - 4, 10 - 6, 10 - 9, 10 - 12, 10 - 15 M) were harvested at the end of the 1st, 3rd, and 5th day. With comparison to the control, these hormones caused an increment in the number of germinating seeds at the end of days 1 and 3 by accelerating the seed germination. Root and shoot lengths were augmented by both hormones at all hormone concentrations tested. The highest elongation was recorded in 10 - 6 M progesterone and 10 - 9 - 10 - 12 M β-estradiol. Similarly, activities of α-amylase and superoxide dismutase were increased by all concentrations of both hormones, and maximum increases were obtained with 10 - 6 M progesterone and 10- 9-10- 12 M β-estradiol. In the case of superoxide dismutase activity, not only the H2O2 content but also the peroxidase and catalase activities increased. Lipid peroxidation decreased depending on an increase in the antioxidant enzyme activities. In the present study, it was demonstrated that progesterone and β-estradiol even at low concentrations increase the germination velocity and resistance to stress conditions by changing the activities of some biochemical pathways.

“…Their results are in agreement with our results for Cicer species. It was shown that mature dry seeds of chickpea contained high levels of ABA (110 ng g À1 FW), which decreased (6.4 ng g À1 FW) in the early phase of germination, while the ABA content increased at 18 h (608 ng g À1 FW), diminishing subsequently to a very low level (0.8 ng g À1 FW) until 96 h (Iglesias and Babiano 1997). Hartung et al (2002) detected ABA concentration in chickpea and lupin (Lupinus angustifolius L.) in acid (pH = 4.8) and alkaline (pH = 8.0) soils.…”

“…So far evaluations of wild Cicer species for useful traits have provided useful data. However, relatively little is known about endogenous plant hormones in chickpea (Munoz et al 1990;Iglesias and Babiano 1996;Iglesias and Babiano 1997;Turnbull et al 1997;Emery et al 1998;Hartung et al 2002). Moreover, these studies conducted on endogenous plant hormones have been detected in cultivated chickpea.…”

All processes that regulate of growth, differentiation and development and also stomatal movement are influenced by endogenous hormones in plants. Research related with endogenous hormones is known for cultivated chickpea (Cicer arietinum L.), while in wild chickpeas no data existed. In this study, C. bijugum K.H. Rech.; C. chorassanicum (Bge) M. Pop.; C. cuneatum Hochst. ex Rich.; C. echinospermum P.H. Davis; C. judaicum Boiss.; C. pinnatifidum Jaub. et Sp.; C. reticulatum Ladiz.; and C. yamashitae Kitamura were evaluated for variations in endogenous plant hormone concentrations; indole-3-acetic acid, zeatin, gibberellic acid, and abscisic acid in both leaf and pod. It was concluded that there was a great variation on endogenous plant hormones among the annual wild Cicer species. The data may support selection for various attributes.
