Developmental responsiveness of salt-tolerant and salt-sensitive genotypes of Lycopersicon

Abstract
The interaction of life-cycle stages and salt stress was evaluated in 36 accessions representing 7 wild Lycopersicon species and the cultivated species. Germination response times increased and early seedling growth rates decreased in all accessions at 100 millimolar NaCl. Wild ecotypes exhibiting rapid salt germinability were identified among L. glandulosum, L. pennellii, L. pimpinellifolium, L. peruvianum and landraces of L. esculentum. LA716 and PI174263 had superior stability in germinability under salt stress. Stability of seedling growth rates was highest in 2 accessions of L. esculentum (cv. Edkawy and PI174263), followed by wild ecotypes of L. peruvianum, L. glandulosum and L. parviflorum. No correlation was found between germination performance and growth performance. -from Authors
