Abstract :This study aimed to determine the glandular structures and trichome biominerilization of the husks of \\\'Palaz\\\' hazelnut cultivars during the period when glandular trichomes are dense. The specimens were collected from Altınordu, Ordu, Turkey. The secretory structures in the fresh husk samples were examined both by scanning electron microscopy (SEM) and stereo microscopy. Energy-dispersive X-ray (EDX) analyses were performed using a JEOL JMS-7001F SEM equipped with secondary electron (SE) and backscattered electron (BSE) detectors. Five types of glandular structures were found on the husk surface. A total of 8 minerals including C, O, N, K, Ca, Cl, Si and Mg were determined in the glandular trichomes examined. Among these minerals, C, O, N, K, Ca minerals were determined in all trichome types with different percentages. The most abundant minerals in glandular trichomes are carbon and oxygen minerals.
