بررسي آرايش و عمق كشت بذر بر خصوصيات جواني زني و استقرار گياهچه به منظور اهلي سازي نوروزك (Salvia leriifolia Benth)

A Study of the Effect of Seed Sowing Design and Depth on Seedling Emergence and Viability in Order to Domestication Nowruzak (Salvia leriifolia Benth.)

Nowruzak (Salvia leriifolia) of Lamiaceae family has a good capability for domestication in Khorasanʹs natural habitats. In order to investigate the effect of sowing design and depth in seedling emergence and permanence, a split plot experiment based on a randomized complete block design was performed with three replications. Results indicated sowing design in all three parameters, sowing depth in number of days for emerging were significantly differents (p<0.01), Sowing design*depth was significantly different in percent emergence (p<0.01) and seedling permanence (p<0.05). The most emergencye percentage (28%) was in plot sowing and 1 cm sowing depth. More sowing depth increased the number of days to emergence, and the most percentage of viability (68.7%) was in plot sowing and 1.5 cm sowing depth.
