Results Regarding the Stage of Some Growth and Reproductive Elements in Primula officinalis Hill.

Abstract

This paper aims to study aspects of biology and cultivation technology for introduction into the culture of the species Primula officinalis Hill., medicinal valuable plant both from a phytotherapeutic and economic point of view. The species Primula officinalis Hill. is popularly known as cuckoo's beak, aglic, aglicel or cuckoo's boot The research was performed on plants harvested from spontaneous flora (Rucăr-Bran area). Then the plants were acclimatized in the greenhouses of NIRDSPB Braşov, Technology laboratory. After acclimatizing the material, a rigorous selection was made, choosing the most uniform plants in terms of number of leaves, height and health. The experimental factors were factor A - distance between rows with graduations: 25 cm, 50 cm, 75 cm and factor B - distance between plants in a row with graduations: 10 cm, 25 cm, 50 cm. Our results shown that the variant with a large nutrition space (75/25 cm), with an average number of seven plants grown in a row, has an average of eight stems with flowers on each plant, being clearly superior to the other variants. The production of fresh herba (kg/ha) for the species Primula officinalis L. was influenced by both factors (A and B). By variance analysis regarding the two factors studied on the average number of flowering stems it is found that the number of flowering stems depends, largely, on the nutrition space.
