رازک (humulus lupulus)، گیاه دارویی- زینتی با ارزشی است که به صورت وحشی در مناطق جنگلی ایران (شمال کشور) رویش می نماید. در دهه های اخیر با گسترش حریم روستاها و شهر ها به سمت جنگل، رویشگاههای این گیاه در معرض تخریب شدید قرار گرفته است. این پژوهش با هدف بررسی امکان ارائه پروتوکلی جهت ریزازدیادی گیاه رازک با استفاده از ریزنمونه نوک شاخساره و گره انجام شد. ریزنمونه های گره از پایه مادری تهیه و پس ا...

Four non-host plant extracts from Bifora radians, Arctium lappa, Humulus lupulus and Xanthium strumarium, were tested against adult grape berry moths, Paralobesia viteana, for their potential as repellents or oviposition deterrents. Responses were compared with those elicited by the major component of the P. viteana sex pheromone. Moths of both sexes exhibited varying electroantennogram (EAG) r...
OBJECTIVE Many biological studies have been done to determine the activity of medicinal plants on gastrointestinal function. Since acetylcholine is the major transmitter involved in the gastrointestinal motility and there are some evidences regarding the cholinergic modulatory effect of hops extract, in the present study spasmolytic and antispasmodic action of hops (Humulus lupulus) on acetylch...
Chemically induced polyploids were obtained by the colchicine treatment of shoot tips of Humulus lupulus L. 'Sybilla'. Flow cytometry revealed that most of the treatments resulted in the production of tetraploids. The highest number of tetraploids was obtained when explants were immersed in 0.05% colchicine for 48 h. A field experiment was conducted to compare diploid and tetraploid plants and ...
