Orchid is one of the most important cut flowers, grown in Sri Lanka for export and local market. One of the majors constrains in expanding the orchid cultivation is limited supply of quality planting materials. Micropropagation techniques can be successfully applied for mass propagation of orchids by the micropropagation is expensive thus increase the cost

Broomrapes (Orobanche and Phelipanche spp.) rely on the presence of a host plant for nourishment. Based on the release of specific molecules by the crop plant, their seeds germinate and eventually establish a vascular connection with host roots through a haustorium. Therefore, they deprive their hosts of water and nutrients, posing a severe threat to

It is extremely challenging to control the Leucinodes orbonalis Guenee, also known as the brinjal shoot and fruit borer (BSFB) in brinjal cultivation. Considering the prevailing dangerous effects of chemical pesticides on human health and ecology, biopesticides can be an effective weapon to sustain against BSFB. Among the different types of biopesticides, Spinosad was found

Perillus bioculatus F. (Heteroptera, Pentatomidae), or the two-spotted stink bug, is considered an important predator of Colorado potato beetle egg masses, larvae and adults. He is attracted to the volatile substances emitted by damaged plants. In Bacau County, the species was observed in 2022 in the eggplant culture at Vegetable Research and Development Station Bacau,

The need for breeding research to obtain new cultivars of baking pumpkin results from the fact that in the Official Catalog of Cultivated Plant Cultivars in Romania, edition 2021, there are only 4 cultivars: ‘Alb mare’, ‘Dorin’, ‘Baron’ and ‘Tudor’. As a result, at Dabuleni Research-Development Station for Plant Culture on Sands (RDSPCS), in the

The present paper studied the influence of mineral or organic fertilizers, applied together or separately, to soil or foliar administered in three applications between 51-89 BBCH, on the processes of flowering, growth, and fruiting of three cultivars of tomato grown in protected space at the National Institute of Research Development for Biotechnologies in Horticulture Stefanesti.

Bell pepper has an important content of vitamins (C, A, E and B), minerals and sugar. It ranks the fourth place in Romania, after tomatoes, onions and cabbage. Grafted bell pepper crops from Romania obtain higher productions compared to nongrafted bell pepper crops. The objective of the paper has been to establish the effect of

National Institute of Research and Development for Potato and Sugar Beet Brasov is working constantly to create new potato cultivars adapted to changing climatic conditions, with high yield and resistance to diseases, suitable to the quantitative and qualitative demands of consumers. Field experiments were carried out in the years 2018 – 2019 using a complete

The warming trends of Romania’s climate create favourable conditions for growing sub-tropical species. Meanwhile, low temperatures during the winter period do not always follow a similar increasing tendency throughout the country. The objective of this work was to use some models that would identify areas where climate conditions are likely to be suitable for fig,

Due to their nutritional and therapeutic properties of the fruits, elderberry orchards started to gain more and more ground in Romania as well. Therefore, the purpose of this research was to improve soil quality and yield production in an elderberry orchard from Carastelec by applying both organic and mineral fertilizers. For this purpose, five fertilization

Similar to apple, pear is one of the most important horticultural crops with high nutritional and economical value. The biological and economic traits of the specie, as well as the fruits quality, make the pear growing much appreciated and to be given an increasing importance. Five pear cultivars (‘Paramis’, ‘Paradox’, ‘Paradise’, ‘Isadora’, ‘Pandora’) registered in

In Romania, in the last three decades, it was registered a decrease of the vineyards surfaces planted with table grapes, this generating an increase in imports of this very healthy aliment. At the same time, the climate changes registered in recent years such as dry periods alternating with torrential rains, or climatic accidents which affected

Saccharomyces cerevisiae is the predominant yeast species in spontaneous wine fermentations and thus it is the main responsible for the chemical and sensory properties of wines. The use of autochthonous yeast strains, besides assuring the maintenance of the typical sensory properties of the wines of any given region, can contribute to promoting or retaining the

The current study aimed to describe the performance of five table grape cvs. recently introduced in the agro-environmental conditions of southern Oltenia.
