Leaf and Root-growth Characteristics Contributing to Salt Tolerance of Backcrossed Pepper (Capsicum annuum L.) Progenies under Hydroponic Conditions

The aim of this study was to determine the genotypic differences in salt tolerance third back-crossed peeper progenies and their respective parents through examining changes shoot growth at agronomical, root morphological leaf development physiological levels under stress. A hydroponic experiment conducted by using an aerated Deep-Water Culture (DWC) technique a controlled chamber Erciyes University, Agricultural Faculty Kayseri, Turkey. Five pepper plants (BC3-1, BC3-2, BC3-3, BC3-4, BC3-5) were selected from backcrossed (BC3) Sena Kopan. Plants grown 8 L pots filled continuously nutrient solution two electrical conductivity (EC) (control 1.0 dS m−1 8.0 m−1) RBD design with four replications for six weeks. Significant reductions leaf, fresh dry biomass productions, total area, length, volume recorded On other hand, significant among existed. Particularly progeny BC3-3 more tolerant characterized salinity than parents. This highly associated vigorous (root weight, length volume) photosynthetically active leaves (total chlorophyll index, chloride exclusion) These traits could be useful characters select breed salt-tolerant varieties sustainable agriculture future.
