Cím:	Evaluation of osmotic stress tolerance of winter wheat landraces / E. Seres, Zs. Erdős, A. Hanász, K. Magyar-Tábori, L. Zsombik
Dátum:	2016
Megjegyzések:	Responses of 50 winter wheat (Triticum aestivum L.) landraces to osmotic stress induced by polyethylene glycol (PEG, Mw 600) were studied during early development of seedlings in hydroponic experiments.Seeds were soaked in aerated tap water for 24 h then they were placed in transparent polystyrene boxes onto horticultural perlite previously soaked by 60 ml water (control treatments) or PEG 600 solution (10%). Seedlings were cultured in plant growth chamber, under 10 h illumination, 80% relative humidity and 20?C for 11 days. Water supply was made twice a day by spraying of water or PEG 600 solution (10%). At the end of experiments the length of leaves and roots were measured and stress index (SI) was calculated for comparing genotypes (growth parameters of PEG treated seedlings/growth parameters of control seedlings x 100).Seedlings showed significant differences in their growth parameters in control treatment: the longest leaves developed on 'Marcaltói', 'Nagyatádi' and 'Pócspetri' landraces (196; 192 and 190 mm, respectively), while the shortest leaves were detected on 'Gégényi', 'Gamási' and '1407-KV' landraces (125, 130 and 130 mm, respectively). The longest roots were observed on ♭Bánkúti marquis' (171 mm), while the shortest roots developed on 'Jászárokszállási' (71 mm) landrace.Considering SI values 'Gamási' and 'Fóti' landraces exhibited exceptionally good results (SI indeces were above 90) in osmotic stress tolerance in both growth characters. 'Homokszentgyörgyi' and 'Háromfai' landraces also showed good stress tolerance in their leaves growth, while 'Jászárokszállási' in its root growth.
