Abstract
This study was carried out to determine the response of three faba bean cultivars to growth regulators treatments to reduce faba bean flowers abortion and increase seed production. Two field experiments were carried out at Dakahlia Governorate, Egypt, during 2009/2010 and 2010/2011 seasons. It could be achieved through selecting some promising faba bean (Vicia faba L.) cultivars i.e. Giza 716, Sakha 1 and Giza 3 and foliar spraying with plant growth regulators treatments i.e. control, 50 ppm GA3, 100 ppm GA3, 50 ppm IAA and 100 ppm IAA.
Faba bean cultivars significantly differed in averages of plant height, number of branches/plant, number of shedding flower, shedding percentage (%), number of pods/plant, number of seeds/pod, number of seeds/plant, seed yield (g)/plant, 100–seed weight and seed yield (ton/ha). Giza 716 cultivar significantly exceeded other studied cultivars in all studied characters except number of shedding flower and shedding percentage, while, Sakha 1 cultivar produced the lowest averages of these characters.
Spraying plant growth regulatosr significantly affected plant height (cm), number of branches/plant, number of shedding flower, shedding percentage (%), number of pods/plant, number of seeds/pod, number of seeds/plant, 100–seed weight (g) seed weight of plant, and seed yield (ton/ha). Highest numbers of shedding flowers and shedding percentage % were obtained. Spraying GA3 or IAA at 100 ppm surpassed the control treatment by 31.6 and 4.10 %, respectively in number of shedding flowers/plant.
This investigation is an attempt to study the role of plant growth regulators for reducing flowers abortion of some faba bean cultivars.
