Preliminary studies on plants regenerated from endosperm-derived callus of kiwifruit (Actinidia deliciosa var. deliciosa)

Abstract

To show differences between plants of Actinidia deliciosa var. deliciosa regenerated from endosperm-derived callus (with 3C amounts of DNA) and those obtained from seeds, observation of their stomata and leaf hairs density was carried out. Stomata and leaf hairs are the features which are often related to ploidy status of plants. Our observation revealed that for plants, which represents 3C DNA level, stomata density was higher than for plantlets showing 2C DNA content. Additionally, density of leaf hairs seems to be also higher in regenerants. This is the first morpho-histological studies of plants regenerated from kiwifruits endosperm tissue.
