Genetic stability of in vitro conserved germplasm of Humulus lupulus L.

Genetic and epigenetic stability of cryopreserved and cold-stored hops (Humulus lupulus L.).

Conventional cold storage and cryopreservation methods for hops (Humulus lupulus L.) are available but, to our knowledge, the genetic and epigenetic stability of the recovered plants have not been tested. This study analyzed 51 accessions of hop using the molecular techniques, Random Amplified DNA Polymorphism (RAPD) and Amplified Fragment Length Polymorphism (AFLP), revealing no genetic variat...

Assessment report on Humulus lupulus L., flos

Inhibitors of nitric oxide production from hops (Humulus lupulus L.).

Nitric oxide (NO) plays an important role in many inflammatory responses and is also involved in carcinogenesis. In the present study, we investigated the inhibitory effect of extracts from Humulus lupulus L. on both the production of NO and the expression of inducible NO synthase (iNOS) in mouse macrophage RAW 264.7 cells. The production of NO was induced by a combination of lipopolysaccharide...

Predicting Offspring Performance in Hop (Humulus lupulus L

J. Am. Soc. Brew. Chem. 68(3):125-131, 2010 Genetic information for male and female hop accessions is limited, hampering parental selection to maximize offspring productivity. Our objective was to determine whether amplified fragment length polymorphism (AFLP)derived genetic distance (GDmm) estimates and coancestry estimates from pedigrees (GSped) between parental pairs could be used to predict...

Photosynthetic activity of selected genotypes of hops (Humulus lupulus L.) in critical periods for yield formation

This paper evaluates the influence of genotype on the photosynthetic activity of hops in the period critical for generating yield. Results over three years from measuring the photosynthesis rate statistically show an increase in the photosynthetic activity of hop plants in the flowering stage. The average photosynthetic rates from measurements on the second date (BBA 65) in the years 2007, 2008...
