Tytuł: Effect of seed size, density and depth of sowing on the germination and survival of psammophyte seedlings

Abstrakt:

Under laboratory conditions the relationship was studied between the seed size, the density and depth of sowing, and the germinating process and its time, the fixing of seedlings and their survival in Corynephorus canescens (L.) P. B., Spergula vernalis Willd. and Androsace septentrionalis L. The factors enumerated above appeared not to affect the germinating capacity and power, but they were found to have an influence on the rate of growth of the germs (thus also, indirectly, on the rate of seedling growth), and on the survival of germs and seedlings. As a result of a high rate mortality of germs at high densities, the numbers of seedling survivors were similar, regardless of the number of seeds sown.
