Abstract EN

This experiment was carried out at the College of Agriculture, University of Basrah, Gharmat Ali during the period from 20 / 8 / 2009 up 1 / 6 / 2010 with the objective of studying the effect of activated yeast suspension, and time of cutting and their interaction on, certain active substances of Lawsonia inermis L.

Minite.

The experiment included 6 factorial treatment, in whichs two factor namely activated yeast extract (at concentration of 0, 1, and 2 g / L) and the time of cutting (7 / 12 / 2009 and 1/ 6 / 2010) was investigated.

The plants were treated by spraying the shoot system three times at one month intervals, A completely randomized block design was used in a factorial combination of the two factor and eight replicates.

The results were analyzed using the analysis of variance and revised least significant test was used to compare mean values at 0.05 probability level.

The results may be summarized as follows : Treatment with activated yeast suspension at 2g / L caused a significant increase in plant height, number of lateral branches, and number of leaves, comparily with yeast suspension at 1g / l and the control.

The treatment 2g / L activated yeast extract gave a significant increase in leaf content of active constituents (Tannins 5.88%, Lawsone pigment 1.1356%) in comparison with plants treated with 1g/L yeast extract (Tannis 5.60%, Lawsona pigment 1.107% and) and the control plants (Tannins 5.01%, Lawson pigment 1.019%) second date of cutting had a significant affect in increasing all vegetative growth characteristics and active constituents.
