| Abstract | ||
| This study was conducted in the field of the Department of Horticulture and Landscape design / College of Agriculture and Forestry / University of Mosul in Nineveh province, and continued search field at the same location for the experience of two years for twenty-four months, period from early March 2011 until the end of March 2013. Used three types of turf is two types of turf grasses Cynodon dactylon and Dichondra repens. In order to obtain green turf grass so that it remains a conservative on the greening of color in different seasons of the year and to study the response of these types for two concentration of growth retardant Paclobutrazol 0.02 gr.m2-1 and 0.04 gr.m2-1. and two concentration from seaweed extract Nap (Ascophyllum nodosum 24 %) 1 cm3.L -1 and 2 cm3.L-1 and the extent of their influence in the growth of these types . Experiments carried out using a randomized complete block design and system split plot (RCBD Factorial within Split - Plot Designs) and this included experience with the control treatment (15) treatments with three replicates. treatment with Paclobutrazol 0.04 g.m2-1 resulted to an increase in the fresh and dry weight of the cuts and increased total chlorophyll in the second season . And the use of concentration 2 cm3.L-1 for Nap led to the significant difference in color during the months of September and October and increased the proportion of chlorophyll during the spring. We recommend planting Dichondra to get a rough flat green all year round compared to summer types Bermuda grass Cynodon dactylon (Unhulled and Panama) in order to grow four seasons and the superiority of moral qualities, color and number of cuts and total chlorophyll in the leaves in the winter. | ||
