Effects of NaCl Stress on Callus Proliferation and Plant Regeneration from Mature Embryos of Bread Wheat (<i>Triticum aestivum</i> L.) Cultivars Mahon Demias and Hidhab

Abstract: An in vitro experiment with two cultivars, Mahon Demias and Hidhab of bread wheat (Triticum aestivum L.) exhibited appreciable callus induction but differed significantly in the capacity of calli proliferation and regeneration under salinity stress; even though Mahon Demias appeared relatively more tolerant than Hidhab. The results indicated the need to optimize a robust protocol for callus induction, maintenance and regeneration before selection process for tolerance to salinity is embarked upon.

“…Nevertheless, the studies about behavior under saline conditions in stylosanthes species referred only to germination (Gonela et al 2004, Silva et al 2014) and plant growth (Lovato and Martins 1997;Gonzá-lez et al 2000;Fuentes et al 2010). In this regard, programs of in vitro selection for tolerance to abiotic stresses could be a useful tool; however, this strategy is dependent on the development of efficient and reliable callus induction and plant regeneration systems (Benderradji et al 2007). Following this orientation, callus cultures are commonly used as an in vitro technique for biochemical and physiological studies of the response to salt and water stress at cellular level (Gandonou et al 2006;Liu et al 2006;Kaviani 2008).…”

“…In vitro technology, especially plant tissue culture offers many unconventional techniques for crop improvement (Dennis Thomas and Sreejesh, 2004). In vitro culture of plant cells and tissue has attracted considerable interest over the recent years because it provides the means to study the physiological and genetic processes of plants in addition of offering the potential to assist in breeding improved cultivars by increasing the genetic variability (Benderradji et al, 2007). According to Larkin and Scowcroft (1981) it is now generally accepted that plant cell culture itself generates genetic variability increasing cell mutation frequency.…”

“…Similarly, NaCl (0, 250 and 500 mM) were used to create salinity effect on 10-d-old seedlings of wheat (Mutlu et al 2009). Two wheat cultivars, Mahon Demias and Hidhab exhibited appreciable callus induction but differed significantly in the capacity of calli proliferation and regeneration under salinity stress (Benderradji et al 2007). In vitro studies on salt tolerance were also carried out with two indica rice cultivars, CSR27 (salt tolerant) and HBC19 (salt sensitive).…”
