Number and size of lupulin glands, grandular trichomes of hop (Humulus lupulus L.) play a key role in contents of bitter acids and polyphenols in hop cone
Original language description
Hop (Humulus lupulus L.) inflorescence, commonly known as ?hop cone?, is valuable for contents of bitter acids, essential oils and polyphenols, used in brewing industry and biomedical application. These compounds are predominantly formed in glandular trichomes, known as ?lupulin glands?. In this study, we investigated chemical and morphological characteristics of lupulin glands by microscopy and HPLC analyses. Even though, no significant correlations were found between lupulin glands and hop cones for contents of bitter acids and polyphenols all ratios between individual metabolites (alpha/beta acids, X/alpha acids, X/DMX) were highly and significantly correlated. The average number of lupulin glands on bract/bracteole ranged from 115 to 713 with 28.5%of variability. Linear regression analyses confirmed that total volume of lupulin glands and total lupulin glands area on bract/bracteole surface highly correlated with contents of bitter acids and polyphenols in hop cone. Therefore, lup
