| Abstract:
Timely harvesting of crops for canning is an important factor in green bean production in respect of yield and quality of crops. Green bean fruits are technologically mature when they have reached a given size (depending on the variety) and the seeds have only begun to form. At this stage of development legumes possess certain biological and chemical properties (see Pavlek and Lozovina, 1970). Studies by Kraus (1866), Hildebrand (1873, 1874), Kooiman (1931, as quoted by Pavlek, 1970), Aleksandrov (1937), Esau (1953 and 1966), Fahn and Zohary (1955) and others have dealt with the anatomical structure of the pericarp of mature legumes of different leguminoses, discussing also legume opening mechanisms. Only a few of these studies include brief descriptions of beans at their physiological maturity. In studying the literature available we did not encounter papers dealing with the anatomical structure of the pericarp of snap bean in the course of technological ripening. This was the reason why we undertook to investigate anatomic properties at the mentioned stage of development in the varieties 'Favorit' and 'Top Crop', bearing in mind that relatively late harvest would increase the yield but lower its quality. It was possible for us to follow up on samples the ontogenesis of the pericarp during technological ripening. | |
