Assessment of the Value of Stomatal Size and Density as Hallmarks of Nonaploid Kiwifruit Plants

Abstract In vitro-derived plants with elevated ploidy levels can display distinguishing features from the they are derived from, especially owing to their indirect regeneration. Genome size affects cell and, thus, plant morphological characteristics. Therefore, stomata traits may be used as a diagnostic feature allowing identification of ploidy. Actinidia chinensis var. deliciosa A. Chev. (A. Chev.), known kiwifruit, is successfully cultured in vitro and redifferentiated into via endosperm-derived calli. To identify differences between hexaploids obtained seeds confirmed nonaploids calli, we analyzed stomata. Our results that coincides mean stomatal length, width, density. Despite this correlation, method cannot distinguish individual hexaploid kiwifruit nonaploid ones because samples different yielded overlapping measurements.
