Autor: E.H. Graven, G. Benians, L. Webber, M. Venter, J. B. Gardner
Publikováno v: Journal of Essential Oil Research. 3:303-307
A glasshouse fertilizer trial (omission principle) was conducted to investigate the effect of the nutrient status of three problem Ciskei soils on the yield and quality of the essential oil of Tagetes minuta L. Acute inherent deficiencies of N and P

The Development ofArtemisia afra(Jacq.) as a New Essential Oil Crop
Autor: E.H. Graven, L. Webber, M. Venter, J. B. Gardner
Publikováno v: Journal of Essential Oil Research. 2:215-220
It has been shown that statistically significant higher oil yields could be obtained from Artemisia afra when the plants were harvested during anthesis and early seed set. The chemical composition of four generations of the same clone was found to be

The initial formation of alcohols during the slow combustion of methane and ethane at atmospheric pressure
Autor: J. B. Gardner, Dudley Maurice Newitt
Publikováno v: Proceedings of the Royal Society of London. Series A - Mathematical and Physical Sciences. 154:329-335
It has been shown in recent papers that during the slow combustion of the paraffin hydrocarbons at high pressures hydroxylation of the hydrocarbon molecule takes place with the formation of the corresponding alcohols in considerable quantities. Thus,
