| Abstract | ||
| This Research studied the effect of soaking Loquat seeds in two periods ( 6 and 12 hours) with a five concentrations of humic acid ( 0, 100, 300, 500 and 700 ml . L-1) and the interaction between them to improve seed germination and subsequent growth of developing seedlings under the lath houses belonged to the Department of Horticulture and landscaping / College of Agriculture and Forestry / University of Mosul during the growing season (2013) . The experiment was Carried out using a Randomized Completely Blocked Design (R.C.B.D) two factors and three replications and using (8 ) Seeds for each experimental unit and thus the number of seeds in this study was ( 240 ) seed . The results obtained confirmed that soak the seeds for a period of (12 hours) recorded significant superior in percentage and the speed of seed germination and most of studied shoot and root growth characteristic in comparison to the treatment soak the seeds for (6 hours) As for the concentration of humic acid, the treatment of (500 ml . L-1) gave the highest percentage of the speed of seed germination compared to other transactions while outperformed treatment (700 ml. L-1) morally on the rest of the transaction and the specially (control) treatment the characteristics of vegetative and root growth of seedlings (seedlings height, the average number of leaves/seedling , leaf area, seedling leaf area , mean of leave chlorophyll content , root length , leaves and root dry weight). The highest percentage and speed of seed germination for the interaction date was when soaking the seed for a ( 12-hour ) with concentration (500 ml . L-1) of humic acid which gave ( 91.67 % and 25.45 ) respectively. | ||
