Silique Picking Force for Canola

The silique picking force of three canola varieties (Brassica napus L.), at three stems moisture content, three amounts of fertilizer and three pull out velocities were measured. Results showed that all used factors had significant effect at 1% confidence on axial ward picking force of siliques. Silique picking force increased with increasing stem moisture content. Data indicated no relationship between silique and petiole lengths with their picking force, while these two quantities were independent. Dimensions of siliques showed that the amount of urea fertilizer and type of variety had significant effect on length of petiole, length, thickness and width of siliques at 1% confidence. Urea fertilizer had no influence on the amount of seeds in canola siliques. © 2010 Friends Science Publishers
