Early rooting in rosemary's (Rosmarinus officinalis L.) cuttings under theinfluence of chemical treatments and collecting time

The present work aimed to verify the early rooting development and the root production in rosemary's (Rosmarinus officinalis L.) cuttings under the in fluence of treatments with sythetics auxins, boric acid and collecting time . The branches were collected at the end of the season and the stakes were prepared and placed into solutions containing NAA or IBA (25, 50, 75 and 10 0 pppm) without and with boric acid and then removed to a chamber of nebuli zation (all experimental work). In all the experimentes, the branches were collected after 30 days, the mean number of rooted cuttings was calculated, along with the mean number of roots per stakes and the dry weight of roots . The end of winter outstood as the best season for all analysed parameters .
