Normal ve Düşük Sıcaklıklarda Pamuğun Çimlenme ve Fide Gelişimine Tuzluluğun Etkisi

The objective of the study was to investigate effects salinity stresses (50, 100, 150, 200 and 250 mM NaCl) on germination early seedling growth six cotton varieties (Lydia, Carisma, Flash, BA151, BA525 ST468) under optimum (25°C) low temperature (18°C) conditions. Germination percentage, mean time, index, stress tolerance length, vigor fresh dry weight were investigated. Results showed that led decreasing in growth, caused retardation time. Under suboptimal temperature, percentage reduced from 86.3% 77.8% length decreased 12.02 cm 5.36 cm. Each increase levels higher than 50 resulted parameters varieties. No observed at NaCl 18°C. Cotton different salinity, while they could tolerate it up 100 mM. It concluded Flash ST468 exhibited better performance both optimal temperatures.
