Effect of some agricultural treatments on roquette seed production [electronic resource].

Includes reference.

This study was carried out at Kaha Farm of Horticultural Research Institute, Kaluobia Governorate during the two successive winter seasons of 1998/1999 and 1999/2000. to study the effect of cutting frequency; i.e. without cutting, one cut and two cuts and gibberellic acid at 0,50 and 100 ppm, as well as their interaction on growth parameter, photosynthetic pigments (Total chloropyll content), flowering characteristics, seed yield and its components, in addition to germination characters of Rocket cv. Balady. Obtained results could be summarized as follows: 1- Cutting frequency caused significant increases in number of leaves, number of main branches, number of seed per pod, seed yield per fed. and seed index. On the other hand, contra results were obtained by cutting frequency with leaf area, chlorophyll content, and, seed-stalk height. These treatments delayed flowering and minimized significantly the number of days needed for germination while germination percentage and seedling length of the produced seed were not significantly affected by number of cuts. The maximum in increases in seed yield were obtained by one cut treatment. Such increases were 21.6 and 23.4% comparing with the control in the first and second seasons, respectively.
