The effect of mineral nutrients and Growth regulator on quality and Concetration of medical compounds in the fenugreek Trigonllafoenum-graecum L.

The research aims to study the effect of mineral nutrients (phosphorus)and Growth regulator (kinetin) on quality and concentration of medical vehicles to fenugreek Trigonallafoenum-graecum L. In two dates of planting For the purpose of achieving the goal. Fenugreek seeds were planted in the first two dates in the second 21/10 and in 5/11 , three levels of phosphorus (0 , 30 and 60) Kgm.h-1 added to the soil , and three Kaintin concentrations (0, 05,100) ppm been sprayed on plants to the degree of wetness and with three replicates for treatment in the botanical garden of the Department of Biological Sciences / basic Education College growth season 2013-2014. The Growth of plants continued to maturing and drought and the seeds were harvested and taken for extraction and separation of medical compounds , and the results showed outweigh the second date on the first date in the content and the concentration of all medical compounds. Given the level 30 Kgm.h-1 phosphorus higher content of extracted medical compounds after the results were analyzed statistically as well as given focus 100ppm kinetin higher content compared to the other concentrations.

Comparison of The Effect of Cogon Grass Extract and Kinetin on Microtubes Production of Two Potato Cultivars Using Tissue Culture

The present study was conducted at Genetic Engineering Department in Agricultural Research Directorate in Ministry of Science and Technology/Iraq in 2013, to evaluate the effectiveness of aqueous extract of cogon grass at concentrations of (0.0 ,0.25, 0.5, 1, 1.5 and 2%) and Kinetin (0.0, 1.5, 3, 5) mg/L on microtuberization of two potato varieties; Daimond and Desire, in two separate experiments. All cultures were placed in a growth room chamber at temeratures of 18-20 °C with darkness for 90 days, until microtubers harvest. Data of microtuber per plant, diameters and weights were investigated. Results showed a positive effect of cogon grass extract at 2% on the number of microtubers and fresh weight (2.1, 104.41 mg, respectively) and at 1% on the diameter (5.52 mm). Desiree cultivar was the best in fresh weight of microtubers (188.41mg). The results of kinetin showed a significant effect on all of the studied traits. The superior kinetin concentration was 5.0 mg/L which gave the highest number of microtubers 2.22, while the concentrations 3.0 and 1.5 mg/L gave the highest values of diameter and weight ( 6.95 mm and 388.38 mg, respectively). The two cultivars did not differ significantly in number of microtubers, while Diamond cultivar was significantly higher in diameter and weight (6.86 mm and 363.45 mg, respectively).
