Abstract:
The present study was conducted during the growing season of 2015/2016 in the Medical and Aromatic Plants Unit Field, Collage of Agricultural, Basrah University, to study the effect of sowing date, plant density and salicylic acid in growth and yield of Coraiandrum sativum (L and its inhibitory activities of some microorganismThe study Includes 12 factorial treatments, which were the combinations of two sowing dates 1/10 or 1/11, two plant densities 25 plant m - 2 or 50 plant m - 2 and spraying with salicylic acid in concentration of 0 ,7.5 or 15 mg.l - 1. A Complete Randomized Block Design in a factorial experiment was used with three replicates. Treatment means were compared according to the Least Significant Differences Test (L.S.D) in level 0.05 was used to compared with Genstat programs. The most important results may be summarized as follows : - 1. Effect of sowing dates : Plants sown on 1/10 gave significantly increases in plant height, leaf number. Plant - 1, number of main lateral branches.plant - 1, dry weights of shoot system.plant - 1, length and dry weight of root system date to the appearance of the first inflorescence, the total number of inflorescences. plant - 1, total number of mini inflorescences plant - 1.total, the productivity of fruit. hectare - 1 (8.96 ton),oil yield.plant - 1 (0.893g), productivity of oil.hectare - 1 (330 kg), refractive index of volatile oil, leaves content of total soluble carbohydrates, leaves content of vitamin C and fruit content of total soluble carbohydrates. Whereas plants sown on 1\11 had a significant effect in total of mini inflorescences, and total protein percentage in fruit.2. Effect of plant densitycultivated plant at 25 plant.m - 2 had a significantly effect in leaf number.Plant - 1, number of main lateral branches.plant - 1 , dry weights of shootSummaryBsystem.plant - 1, length and dry weight of root system , , total number of mini inflorescences.plant - 1, leaves content of total soluble carbohydrates, fruit content of total soluble carbohydrates. cultivated plant at 50 plant.m - 2 had a significant effect in plant height, the productivity of fruit hectare - 1 (8.56 ton), productivity of oil .hectare - 1 (320 kg).3. Effect of salicylic acidPlant sprayed with SA at 15 mg.l - 1 had a significant effect in number of main lateral branches, dry weights of shoot system.plant - 1, dry weight of root, the total number of inflorescences.plant - 1, total number of mini inflorescences plant - 1. weight of 1000 fruit, , refractive index of volatile oil, oil density, leaves content of total soluble carbohydrates, fruit content of total soluble carbohydrates, total protein percentage in fruit. Whereas Plant sprayed with SA at 7.5 mg.l - 1 had a significant effect in leaf number.Plant - 1, length of root system, and the productivity of fruit.hectare - 1 (8.83ton).4. Effect of the interactionsThe Interactions between the study factors, showed a significant effect in most studied parameters.5. Effectiveness of alcoholic extracts and oil of the plant coriander against the two types of pathogenic bacteria to humanThe activities of methanolic and ethanolic extracts and oil of fruit were tested against some types of bacteria Escherichia coli and Staphylococcus aureus at three concentrations100, 200, or 400 mg.l. - 1 by using filter paper disc diffusion method. Each of ethanolic extract and oil of the fruits inhibition in concentrations 400 mg.l - 1, were effected growth of bacteria E. coli. They reached the diameter of inhibition 12 mm. Ethanolic extracts of the fruits at concentration of 400 mg.l - 1 gave the highest inhibition of growth of bacteria staph. aureus amount 12mm and E. coli the diameter of inhibition 10 mm.SummaryC6. Effectiveness of alcoholic exteracts and oil of the plant coriander against two pathogenic fungi to humanThe activities of methanolic and ethanolic extracts and oil of fruit were tested against types two fungi Aspergillus niger and Candida albican at three concentrations 100, 200,or 400 mg.l - 1. Was mathanolic extract of the fruits at concentration of 400 mg.l - 1 gave the highest inhibition of growth of A. nigerand C. albican amount 12mm and showed oil fruit and ethanolic extracts at concentration cultivated of 400 mg.l - 1 the highest inhibition against A. nigerand C. albican amount 10mm.
