Abstract EN
One cultivar and tu,o pure lines of broad bean rvere grown in a nutrient solution containing sir different boron concentrations: 0, 0.05, l.
2.
8 and 32 mgl l.
In deficient plants.
plant grorvth was reduced: the young leaves remained small, wrinkled, thick, deformed and yellowish brown in color ; irregular chlorosis appeared between the veins before leaf abscission : as the deficiency progressed the terminal growing point died.
flower buds were shed without opening and black spots appeared on the rare developing pods.
Symptoms of boron toxicity began rvith a yellowing of mature foliage, follou,ed by, a marginal necrosis and the leaves drop prematurely.
the necrosis and browning of tissue caused by boron deficiency and to.xiciff arises from the accumulation of phenolic compounds.
the boron content in the rvhole plant was closely related to its concentrations in the nutrient solution.
the optimum boron content for mature broad bean plant was betrveen 40 and 90 ppm.
