Sažetak
Seme stočnog graška (Pisum sativum L.) sadrži veliku količinu proteina, amino kiselina, šećera, ugljeno-hidrata, vitamina A i C, kalcijuma i fosfora, te zbog toga nalazi široku primenu. Iako ima skromne zahteve za uspevanjem, stočni grašak se svrstava među kulture koje su osetljive na povećan sadržaj soli u zemljištu. Ispitivanje je obuhvatilo osam sorti (Javor, Jantar, Partner, Kristal, Pionir, Junior, Trezor, Dukat) stvorenih u Institutu za ratarstvo i povrtarstvo u Novom Sadu. Simulirani su uslovi zaslanjenosti tako što su u podloge za naklijavanje dodati rastvori NaCl koncentracija 0, 50, 100 i 150 mM. Određivani su klijavost semena, dužina ponika, masa svežeg i suvog ponika i masa 1000 semena. Od ispitivanih sorti, sorta Jantar se izdvojila kao najtolerantnija na povećan sadržaj soli u podlogama za naklijavanje u laboratorijskim uslovima.
Abstract
Field pea (Pisum sativum L.) seed contains a large amount of proteins, amino acids, sugars, carbohydrates, vitamins A and C, calcium and phosphorous, and hence it is widely used for many purposes. Although field pea has moderate requirements for its growth, it is sensitive to increased salt content in soil. This research included eight varieties (Javor, Jantar, Partner, Kristal, Pionir, Junior, Trezor, Dukat) developed at Institute of Field and Vegetable Crops in Novi Sad. Sodium chloride solutions of various concentrations (0, 50, 100 and 150 mM) were added in growing media to simulate saline conditions. The following were subsequently determined: seed germination, seedling length, fresh and dry weight of seedlings and 1000-seed weight. Among the analyzed varieties, variety Jantar expressed a high level of tolerance to increased salt content in growing media under laboratory conditions.
