| Abstract/Contents: | "The progressive salinization of land is a great area of concern in agriculture production (Greenway and Munns, 1980) and represents the major abiotic stress for plants in arid or semiarid regions. Salts that are generally a common and necessary component of soil and essential plant nutrients, at concentrations as high as 45 ds m-1 (50 mM) can cause reduction in water availability, sodium ions accumulation and mineral imbalances that affect seed germination and plant metabolism (Ali et al. 2001). The inhibitory effect of salinity on germination includes the reduction of germination percentage, delay of the germination process, and loss of seed viability. The effects of germination regulating chemicals in enhancing seed germination under salinity conditions and alleviating salinity stress has been reported in several plant species. A way to alleviate salinity stress is treating plants with biostimulant products. Biostimulants are organic molecules that are often referred to as positive plant growth regulators or as metabolic enhancers, and are presently recognized and entered in the legislation controlling the marketing of fertilizers. When applied in small amounts, biostimulants can promote plant development, increase yields and support plants to overcome stress situations by acting directly or indirectly on plant physiology (Schmidt et al., 2003). Biostimulants include three groups of molecules: plant hormones, humic substances, and free amino acids/peptides. The objectives of this study were (i) to determine whether applications of a biostimulant, (a protein hydrolysate-based fertilizer), manufactured by ILSA in Arzignano (Vicenza, Italy), could promote the germination of three cultivar of Lolium perenne L. displaying different tolerance to salinity; (ii) to study the effect of the biostimulant on the activity of two enzymes (Alpha-amylase and invertase) involved in seed germination and plant growth." |
