Abstract

The aim of this study was to investigate the effect of pea and cowpea sprout extract on germination traits and growth of Pinus eldarica medw. and Cupressus sempervirens L. var horizontalis in laboratory conditions base on a completely randomized design with four replications. The effect of different concentrations of the extracts on germination percentage, germination rate, seed vigor index, allometric index, shoot length, radicle length, fresh and dry weigh of shoot and radicle were investigated. The results of analysis of variance and mean comparisons showed that the effect of extracts on some growth trait and germination of tow species was significant. The highest germination percentage was observed in Pinus eldarica at 20% concentration of cowpea extract. The highest seed vigor of this species was obtained by using 20% extract of cowpea and 10% pea. The highest root dry weight was observed in 40% concentration of cowpea and 10% pea extract. In Cupressus sempervirens L. var horizontalis, 20% of cowpea sprouts and 10% of pea seed produced the highest germination and seed vigor. The highest root length was observed in 30% cowpea sprouts extract. Also, 10% pea extract showed the highest root dry weight. Totally, we can have said cowpea extract lead to better result than pea extract.
