Abstract

Lens culinaris as an important plus grown under semi-arid areas where environmental stresses like drought and salinity are the major problems for its production. Treating with nano-particles can solve this problem and improve crop growth under stressful circumstances. In this study, three treatment combinations as Control: distilled water, Salinity: 100 mM NaCl concentration, and Sal-Si: 1 mM nano-silicon dioxide concentration plus 100 mM NaCl concentration were applied on four cultivars. Some traits including germination percentage (GP), shoot length (SL), root length (RL), seedling fresh weight (FW) and seedling dry weight (DW) were recorded. The treatment by trait biplot model described about 96% of the observed variation for the recorded traits and the polygon tool identified seven vertex treatment combinations as; Sal-Si-G1, Sal-Si-G3, Sal-Si-G4, Con-G1, Con-G2, Con-G3 and Sal-G1. The vertex treatment combination Con-G3 was the best in GP, SL, RL and FW, while the vertex treatment combination Con-G2 was the best in DW. According to the ideal entry, three classes of treatment combinations were detected, Class I, treatments with high discrimination ability (all cultivars in control treatment), which were followed by the all cultivars at salinity stress as Class II. Finally, Class III, treatment combinations with low ability for discrimination among traits as all cultivars at salinity stress plus nano-silicon dioxide application.
