Trabajo presentado al VII International Symposium on Pear Growing. Talca (Chile), enero 1997
This study was carried out on mature Comice pear trees on BA29 quince rootstock. Labelled B (99.63 Atom % B-10) was applied postharvest as boric acid. Treatments were: foliar B at 500 ppm; foliar B (500 ppm) plus urea (2.5%), and soil B at the same per tree rate as the foliar treatments (8 g boric acid/tree). Postharvest foliar B was mobile and it was transported out of the leaves into storage tissues for the next year's growth, but soil applied B remained in the roots and very little was transferred to the above-ground portions of the tree until one month after full bloom. The storage pool of B partitioned equally among young developing tissues but fruits were very strong sink of reserve B. Boron from the storage pool was diluted during the growing season as roots absorbed new-non labeled B from the soil. Isotope ratios revealed that regardless of tissues sampled, the addition of urea increased B uptake. These results showed that it is advantageous to mix both compounds in a postharvest fertilizer program.
