Abstract

There is a species of barberry that cultivated in arid and semi arid area of Iran (south Khorasan province) which is widely used as a food additive for rice cooking. Fruits of this species have no seed while wild types at the same area produce seeded fruits. In this experiment, mechanism of seedlessness was evaluated by in 'in vitro POLLEN viability test, in situ, POLLEN tube growth study in pistil, histological study of ovule development and field pollination experiment. Histological study was done in seeded wild type barberry (Berberis crataegina DC) as well. In vitro test of POLLEN germination in SEEDLESS BARBERRY showed that POLLEN had viability of about 54%. SEEDLESS BARBERRY produced 20% seeded fruit when pollinated with POLLEN of wild types barberry. There was dramatically decrease of fruit set in emasculated unpollinated flowers of SEEDLESS BARBERRY. Plenty of POLLEN grains (about 370) were observed on stigma of each flower at 12 hr after flower opening. Most of them germinated and penetrated intracellular area of stigma surface but no POLLEN tube reached to ovary. About 41% of studied ovaries in SEEDLESS BARBERRY did not have any EMBRYO SAC or had very small incomplete EMBRYO SAC. In SEEDLESS BARBERRY, in some case unfused polar nuclei were clearly recognized at 14 days after anthesis. However, In wild type, double fertilization was accompanied by disappearance of polar nuclei. In seeded barberry, the cellular endosperm became clear at seven days after anthesis. At 21 days after full bloom, all ovules of SEEDLESS BARBERRY degenerated while at the same time in wild seeded type, one or two ovules of each flower were normal and were developing toward complete seeds. In general, it can be concluded that SELF INCOMPATIBILITY have main role in seedlessness in barberry but high frequency of abnormal ovules and single fertilization can be considered as another reason of seedlessness. Fruit of SEEDLESS BARBERRY is probably set via simulative PARTHENOCARPY.
