TOWARDS A SEEDLESS CULTIVAR OF KINNOW MANDARIN V. EMBRYOGENESIS OF PICKED AND DROPPED FRUITS
NAFEES ALTAF AND M. MOHSIN IQBAL
Abstract
Nucellar polyembryony in picked and dropped fruits was studied. There were 2,3, 4 and 5 leaf embryos with balanced normal germination. The significant differences were imbalanced growth with 8.7% thin shrinked leaves in embryos of picked fruits and 12.9% embryos without root system in dropped fruits which upon grafting had 100% plants with leaf abscission trait. Presence of abscission trait in vegetative parts of the branch and in the embryo indicated that the trait is of genetic origin as the embryos are derived from cell lines present in the vegetative parts.
