STUDY REGARDING THE INFLUENCE OF SUBSTRATE TYPE ON SOME PARAMETERS OF GROWTH OF GERBERA SEEDLINGS.

The study was conducted at the University of Agronomic Sciences and Veterinary Medicine of Bucharest, the greenhouses Hortinvest. In the experiment I followed the influence of some factors on the germination of gerbera seeds. We used 12 types of substrate, V1-100% peat with pH 5.5; V2 - 100% peat with pH 4; V3 - 100% Perlite; V4 - 50% Perlite + 50% peat with 5.5 pH; V5 - 50% Perlite + 50% peat with 4 pH; V6 - 100 vermiculite; V7 - 50% vermiculite + 50% peat with pH 5.5; V8 - 50% vermiculite +50% peat with 4 pH. V9 jiffy seven peat pot; V10- pot with perlite; V11- pot with vermiculite and V12 pot of grodan, I tested the capacity of emergence at seeds stored in different condition. The varieties of gerbera were analized, regarding the percent of emergences and growth rate of the seedlings. The best variants with the highest percentage of seeds emerged were those where we used peat and mixed of perlite and peat with a pH of 5.5. [ABSTRACT FROM AUTHOR]
