The assessment of appling drought stress on different canola (Brassica napus L.) cultivars
In order to study hardness of drought stress applying in different growth time on germination and seedling growth of different canola seed cultivars, an experiment was laid out on factorial arrangement in completely randomized design with 4 replications. In this study different growth time were normal irrigation (as control), irrigation until flowering, irrigation until padding and irrigation until seed filling stages and canola cultivars namely SLM046, Licord, Opera, Zarfam Orient, Okapi. After 7 days the whole plant and root length, root/shoot ratio, seedlings dry weight, MDG1, FGP2and DGS3. The results showed that the cultivars had significant effect on root/shoot length (p≤0.05), seedling dry weight and FGP (p≤0.01). Less irrigation also had significant effect on whole plant, root length, root/shoot ratio, seedling dry weight, abnormal seedling (p≤0.01) and hard seed (p≤0.05). The interaction of cultivar×different less irrigation stages showed that shoot/root ratio in all stage of applying drought stress, except flowering stage (p≤0.05).
