English Abstract

Afield experiment was carried out at the research station of the Field Crops Department / University of college / Tikrit of Agriculture in the winter season 2017/2018 to investigate the effect of nano cooper and cytokinin spraying in physiological characters for Coriandrum sativum L.

.

The first factor includes four levels of Nanocrystalline copper (0,1, 2 and 3) g/l .While the second factor included four levels of cytokinein (0, 50, 100 and150) ppm.

The treatments were made by spraying on the vegetative plant after maturing (4-8) leaves of the plant.

The experiment was performed by using experiment in which treatments are distributed according to the design of the complete random sectors RCBD (Randomize Complete Block Design) with three replicates each containing 16 experimental units.

The results showed that: The spraying of nano-nucleic acid at the concentration of 1g is higher than others in most studied traits of plant height (91.70)cm, number of branches (9.46),leaf area (5.25) cm, paper density index (0.00656), percentage of leaves (1.91) , the dry weight of plant ( 189.94)gm,the duratinon of the paper (88,96) and the duration of the dry plant production ( 3559.8 ).

The specific density of the leaves (1.58) The relative growth rate of the plant (0.033) and the growth rate of the crop (3.14) and the net rate of photosynthesis (1.29).

The spraying of cytokinin at the concentration of 100 ppm is higher than others in most studied traits of Plant height (83.95)cm, number of branches (8.26) leaf area (4.19) leaf area index (0.00501) Percentage of leaves (1.59) dry weight of plant 149.51 leaf duration period 77.68 and shelf life of plant dry matter 3053.1 Density Quality (Specific weight of leaves) (1.17) Relative growth rate of plant (0.026) and crop growth rate (2.81) Net rate of photosynthesis (0.96).

The spraying of nano-copper at 1 g concentration with cytokinein at 100 ppm concentration was higher in the studied traits of plant height (93.69), number of branches (10.57) leaf area (5.56) percentage of leaves (1.95) and dry weight of plant (200.67) Plant growth rate (0.0384) and crop growth rate (3.47) Net photosynthesis rate (1.43) The spray combination of nano-granular copper at a concentration of 1 g with cytokinein at a concentration of 50 ppm (0.00670).
