The Effect of Spraying with Benzyle Adnin and Marine Alga Extract (Algazone) in Improving the Phenotypic Properties of Green Landscap

Abstract

Abstract. The experiment was conducted in the fields affiliated to the College of Agriculture - University of Anbar from 1/2/2018 until 30/1/2020 with the aim of studying the response of green landscap to the effect of spraying the benzyl adenine and algae extract through a mixture of herbs for hot and cold areas. The factorial experiment was conducted according to the random Complete block design (RCBD) with three replicates, including Benzyl adenine (BA) at a concentration of (0, 5, 10 and 15) mg-1 liter and algae extract (0, 0.5, 1 and 2) ml liter-1. The results showed a significant increase in the concentration of 15 mg-1 liter-1 in (BA) in increasing the plant density and the number of branches, also reducing the number of shear times reached 44.58 dcm plants2, 9.94 branches. Plant-1 and 6.58 shear), as well as an increase in the susceptibility of run over for the three seasons, summer, autumn and winter with a degree of 3.39, 2.97 and 3.09, in respectively. The same concentration recorded a significantly increased in the color and quality (homogeneity) for the green area for the three seasons, grades were (7.75 and 7.66) for the summer season, (6.95 and 6.89) autumn, 7.29 and 7. 37 in the winter, respectively. The spraying of algae extract with the concentration of 2 ml -1 resulted a significant increase in the plant density was 45.16 dcm plants2, the number of cuts was 9.50 shear. The same concentration increased the degree and the quality of color (homogeneity) for the flat green to the three seasons (7.70, 7.75) degree of summer (7.00, 6.93) degree of autumn (7.39, 7.41) degree of winter respectively.
