Application of calcium and boron directed to inflorescences in production, quality and nutrient accumulation in lettuce seeds

ABSTRACT Calcium and boron are important nutrients in the stages of flowering, pollen germination fruiting process. As these poorly mobile plant, some authors recommend foliar spraying production seeds species. The objective was to study influence calcium boron, via application directed inflorescences, production, quality accumulation lettuce seeds. Four treatments were evaluated (only calcium: 0.72 g/L; only boron: 0.17 joint control), randomized blocks design with six replications. No obtained between for seed (number weight per plant). Using alone or together calcium, a thousand lower compared control, while did not differ from control. differences vigor. affect nutrients, however increased this nutrient directly inflorescences promote an increase vigor
