| Popis: | Study was undertaken to test the effects of soaking seeds Citrus limetta and Citurs limonum in Gibberellic acid (GA3) solutions 0, 100, 500, 1000 mg / L for 24 hours prior on the rate of germination, some morphological characteristics for seedlings also were investigated in this study. Factorial experiment was carried out 4×2×5 in a randomized complete block design with five replicates for each type of seed during the period of March to September 2011. The results showed significant differences in most traits, as it reached the highest percentage of germination for the treatment with 500 mg/l for both types of seeds, while the highest dry and fresh weights of shoot and root, main root length, highest shoot, leaves number and leaf area index were in 1000 mg /l treatment. No significant effect of GA3 treatment on the amount of A, B and total chlorophyll in the seedlings leaves. The best treatment was soaking seed in 1000gm/l Gibberellic acid. The information documented the stimulating effects of seedling be used to increase the ratio of germination. Also gibberellins stimulated effects continues for some seedlings morphological characteristics and progressively with gibberellins seed treatments influence vary according to genotypes of citrus seeds, that can increase concentrations which used in soaking seeds solutions. |
