Abstract
According to the available evidences about the rising of temperatures that causing by global warming and its negative effects on the operation of Crocus sativus L in the country, perhaps use of living mulch with reduction of the soil temperature could effect on plant physiological activities and cause to improve the growing processes of Crocus sativus L plant.
In this case, in center of herb research Tehran Shahed University, an experiment is done on the four year’s old farm in the crop year 2013.The distribution of plot is done on randomized complete blocks design in three times.the implantation density of cover crop (squash ) was considered at three levels ( 75 , 50 and 100 cm).The results show that by using of mulch, there is a significant effect on the flowers number, fresh flowers weight, fresh Tdadgl weight and amount Pkrvsyn.
The results show that the maximum value for the flowers number, fresh flowers weight and Pykrvsyn parameters obtain in sowing the cover crop 50 cm, respectively. Furthermore, the greatest amount of fresh stigma weight, in a distance 50 and 100 cm of cover crop were observed, respectively. The results of this search proved the cover crop desired effect on quantitative and qualitative traits of Crocus sativus L.
