Gheorghe David, Simona Niţă, Adrian Borcean
Common evening primrose or Evening star is an important medicinal plant known as the “supreme antidote”. Original from Central America, it is spread nowadays all over Europe, Asia, New Zeeland and Australia. The plant parts that are used are: seeds, leaves, seed oil, and roots. Therapeutic uses: hypo-lowering cholesterol level, anti-inflammatory. Therapeutic directions: skin diseases, neuro-dermatitis, rheumatism, liver diseases, convulsive cough, etc. Seed oil is a potential treatment for a large number of diseases such as eczema, cancer, multiple sclerosis, rheumatoid arthritis, and in the pharmaceutics industry. The material studied was a population from Sasca, harvested from the Nera River basin. In the paper we present results of biometrical measurements concerning the evolution of the following features: plant height, number of ramifications per plant, number of capsules per plant, volume of 1000 grains, and seed oil content evolution. The study was carried out on three different agri-funds: N 0 P 60 K 60 , N 50 P 60 K 60 , and N 150 P 60 K 60 . Research results point out the positive effect of nitrogen fertilisation on both plant growth and ramification and seed weight features, and the negative impact of fertilisation on seed oil content.
