Hemp is one of the oldest crops in the world and can be used in very different ways. Hemp cultivation was forbidden in Germany since 1982. Since 1996 hemp with less than 0.3 per cent THC content can be grown. To evaluate the available genetic hemp resources 14 monoecious and 26 dioecious hemp varieties and strains were grown in the field in 1996 and analysed for morphological traits. A large variability was found for plant height at different dates, blooming time, stem diameter, fresh and dry… 

Apical bud removal increased seed yield in hemp (Cannabis sativa L.)

It is maintained that hemp producers can achieve a larger seed yield not only by selecting an appropriate cultivar and row distance but also by removing apical buds.

In vitro germplasm conservation of high Δ9-tetrahydrocannabinol yielding elite clones of Cannabis sativa L. under slow growth conditions

This study is of high significance since the encapsulation technology would allow the prolonged storage (thus reducing the cost of labor) of high-yielding C. sativa germplasm selected for the isolation of THC, a high-value bulk active pharmaceutic.

Research in plant genetic resources 1978–2003: General index of the second 25 volumes 'Kulturpflanze'/'GRACE'

A general index of the second 25 volumes of 'Kulturpflanze' 1978–1990/'GRACE' (Genetic Resources and Crop Evolution) 1992–2003 is provided and can be considered as a unique source for research in plant genetic resources.



Crop physiology of fibre hemp (Cannabis sativa L.)

Fibre hemp ( Cannabis sativa L.) may be an alternative to wood as a raw material for the production of paper pulp. The effects of enviromnental factors and cultural measures on the functioning, yield

Characterisation of Cannabis accessions with regard to cannabinoid content in relation to other plant characters

Variation within populations for cannabinoid content, and consistency of chemical characters at the population level were investigated and various combinations of cannabinoid content and other economic plant characters were observed, thus a breeding programme will not be hampered by strict linkage.

Studium der Vererbung des Geschlechts und des Wuchstyps beim Hanf

Results show why the breeding of monoecious hemp with male growth type has been an impossibility, and lethality of Y eggcells has been confirmed.

Organspezifische Entwicklung der 9-Tetrahydrocannabinol (THC)- und Cannabidiol (CBD)-Konzentration während der Vegetationsperiode zweier Faserhanfsorten

In 1992 and 1993 field experiments on monoecious or female plants of the fibre hemp varieties Felina 34 and Kompolti Hibrid TC were performed to test the growth of different organs in three stem
