PARTIAL RESULTS REGARDING THE INFLUENCE OF SOME TECHNOLOGICAL ELEMENTS ON THE YIELD OF DRIED HERBA TO THE PRIMULA OFFICINALIS HILL. SPECIES

Sustainable use of natural resources is one of the great challenges of our time. Thus, there is a return to nature, to homeopathic medicine and to phytotherapy. Primula officinalis Hill, has been used since ancient times in popular medicine due to its many healing properties. The main purpose of the study is the introduction into the culture of the species Primula officinalis Hill. The research started in 2016 by accumulating information on the existing genetic resources. The plants necessary for the establishment of the experiments were brought from the spontaneous flora of Braşov Country. The study aimed to establish the optimal breeding mode, the optimal planting time and nutrition space. These technological links influence the the plant yield but also on the content in active principles. The paper presents partial results regarding the elaboration of cultivation technolog

LAVENDER (LAVANDULA ANGUSTIFOLIA MILL.) - MEDICINAL-ALTERNATIVE SPECIES IN THE STRUCTURE OF CROPS IN AGRICULTURAL FARMS, IN THE CONTEXT OF CLIMATE CHANGE

From the medicinal species Lavender, the inflorescences (Flores SpicaeLavandulae), with a pleasant, characteristic smell, with notes of freshness, are used for therapeutic purposes. The active principle of lavender flowers is the volatile oil, the content of which differs depending on the species, variety, variety, time of harvest or the form of conditioning. Fresh flowers contain up to 0.8% volatile oil, and dried ones up to 1.5%. Lavender flowers have a high content of linalool (a terpene alcohol, which helps to synthesize vitamin E and a non-toxic insecticide), they also contain tannin, bitter principles, resins, pectins and other alcohols (nerol, lavandulol). The volatile oil whose main component is free linalool (40-60%) or in the form of linalyl acetate (40-50%) has medicinal uses.In the volatile oils of Lavandulaangustifolia L., 22 compounds were identified, of which 14 major compounds (in concentration above 0.2%) represented 99.53% of the total

Preliminary aspects concerning the introduction into crop of the Dracocephalum moldavica L. (Moldavian dragonhead) species under the environmental conditions of NIRDPSB Brasov

The researches are carried out within the research project ADER 2.4.1., during the years 2015-2018, a project coordinated by SCDA Secuieni and to which NIRDPSB Brasov is partner. The overall objective of this study is to introduce in crop a valuable medicinal species from Lamiaceae family, respectively Dracocephalum moldavica L. (Moldavian dragonhead) species. This objective resides from the growing concerns of consumers about nutrition, preservation of a proper health status, from the increased responsability for maintaining and protecting the environment. Originally from Central Asia and acclimatized in Central and Eastern Europe, the Moldavian dragonhead is traditionally used for medicinal purposes worldwide, for its sedative and analgesic properties, but also as a good anti-rheumatoid, antitumoral, antimutagenic, antiseptic and antioxidant. It was followed the establishment of multiplication way, the seed norm/ha, the optimum sowing time and the optimal nutrition space, in order to establish a crop technology adapted to the environmental conditions of Bârsa county. To determine the optimum sowing time was set up a single factor experience of five variants and three repetitions. For determining the optimal nutrition space of the plant was established a bifactorial experience of nine variants in three repetitions. At each variant / repetition, biometric measurements were made on the plants, and the fresh and dried herba production was also evaluated. The results were subjected to the statistical analysis, so that the best variants were highlighted, depending on the experience set up and its purpose. The contribution with new information on the crop technology of Dracocephalum moldavica L. species leads at the enrichment of knowledge in this field, as the information in the literature is more geared towards studying the species in terms of active principles in the plant, rather than crop technology

Responses of different potato late blight control technologhies to the use of noninvasive methods

The present study was conducted to investigate potato late blight influence on leaf chlorophyll level. Field experiments were carried out in the years 2014-2016 to the National Institute of Research and Development for Potato and Sugar Beet – Brasov, Romania. It was used a complet randomized block design with four replicates, two planting distance between plants on row and different fungicides. At measurements in early July in 2014 and 2016, the varieties had close SPAD values (SPAD 39.5 and 40.1 for Roclas variety, SPAD 41.9 and 37.5 for Christian variety), which were lower at all varieties compared to the values measured in 2015, at which the SPAD average values were 47.8 at Riviera, 48.0 at Roclas and 49.4 at Christian. In 2014, following the measurements made to Roclas and Christian varieties, there was a close correlation between the SPAD values and the number (0,752 *), respectively the weight of the tubers at nest (0,882 **), while the correlation was negative between the SPAD values and the weight of the aerial part of plants (-0,722) *. In this year correlations between SPAD average values, total yield and commercial one were insignificant. The only year of the experimental cycle in which SPAD average values from variants correlated significantly was 2016, the year leading to the highest SPAD correlation coefficients - totalyield (0,706 *) and SPAD - commercial yield (0,656 *
