Abstract
This study was conducted at the Experimental Station and Laboratory of Vegetable and Floriculture Department, Fac. of Agric., Mansoura Univ., Egypt, during 2015/2016 and 2016/2017 seasons to investigate the effect of some natural products and some alternative chemical growth regulators on rooting response‚ growth and chemical composition of cuttings of rosemary (Rosmarinus officinalis L.) plants. The layout of the experiment was completely randomized block design (CRBD) with three replications. The obtained results could be summarized as the following: It is worthy to mention that the highest values of all studied vegetative growth characters and chemical constituents of rosemary were resulted from treating terminal cuttings with coconut milk at the highest rate (75%) in both seasons. With exception, fresh weight of shoots, which, obtained when treating terminal cuttings with seaweed extract at the rate of 50 % and total phenols percentage, which obtained from control treatment (treating cuttings with water only) in both seasons. Using natural products such as coconut milk, seaweed extraction, yeast extract and honey bee were better than using chemical growth regulators like Indole butyric acid (IBA) in both seasons. It can be concluded that treating terminal cuttings of rosemary (Rosmarinus officinalis L.) with coconut milk at the rate of 75 % as natural growth regulator in order to enhance rooting‚ vegetative growth and chemical constituents.
