Salicylic acid is a stress-signal molecule that is involved in the modulation of growth and development of plants. There is evidence that this stress-signal molecule has a positive impact on the antioxidant defence system, but few studies have been done on determining the most effective concentration and its impact on the growth and development of cabbage plants cultivated in vitro. In the present experiment, we assessed the impact of three different concentrations of salicylic acid (1 mM, 0.5 mM and 0.1 mM) on seed germination indexes, shoot initiation and proliferation, root development, as well as physiologic traits (phenolic and chlorophyll content). It has been found that a concentration of 1mM SA inhibited both seed germination and shoot development, which is probably related with suppression of GA-mediated pathway. Instead, the addition of 0.1 mM SA stimulated shoot proliferation rate, shortened the time for shoot initiation and increased shoot and root elongation. Our results provide the foundation for further studies related to the plant's agronomic performances when cultivated in the field. [ABSTRACT FROM AUTHOR]

Cabbage (Brassica oleracea var. capitata) is a prevalent vegetable crop cultivated for its nutritious leaves, which have a variety of culinary and medicinal use. As a consequence, vegetables such as cabbage are extremely popular among consumer demands. Constraints in the seed production chain highlight the significance of seed germination and crop's growth at the farm level. The production of high-quality seeds is a crucial step in this crop's cultivation since it impacts the success of germination and plant growth. In this study, we aimed to investigate the influence of plant density and seedling planting dates on cabbage seed process performance. This research is a component of a larger project aimed to devise a comprehensive and new modernized strategy for cabbage seed production. The experiment was carried out on 'Silviana' autumn cabbage variety during two growing seasons, a field trial was undertaken to assess three plant densities (low, medium and high) and three seedling planting dates (early, mid-season and late). Cabbage seeds were also subjected to a range of seed viability and vigour tests. [ABSTRACT FROM AUTHOR]

Our study was accomplished in lab conditions at Vegetables Research and Development Station Bacău, aiming to determine the impact of foliar treatment with salicylic acid (SA) over the ability of plants to overcame the water stress. The pot experiment used a randomized block design with four replications and ten plants per variant. Leaves from well-developed plants (30 days old seedlings) were sprayed with 1 mM SA solution until both sides were completely moistened. After treatment application, water regime followed as one set was used as a well-water treatment (WW) and the other set as a drought stress treatment (DS) where the plants were restricted watering for the next 10 days. Results showed that tomato plants treated with salicylic acid and exposed to water stress become more tolerant to drought stress induced oxidative damage than those not treated, the values were comparable to those recorded in WW plants. The extent of water stress injury was higher at non-treated DS plants. The results obtained showed that foliar application of SA stimulated the adaptation of plants, improving water-plant relation, allowing to alleviate the oxidative damage. [ABSTRACT FROM AUTHOR]

Bean maize intercropping is an old cultivation scheme practiced at small scale by traditional farmers in Romania. Literature highlights the benefits of intercropping and the constrains related extension of this practice on largest areas. Studies on interspecific interactions have paramount importance in view of development of feasible approaches of environmentally friendly cultivation practices and for genetic improvement specific for performance in intercropping. Five climbing bean varieties were evaluated in sole cropping and in intercropping with one type of sweet maize cultivar. Sowing was successively caried out in an interval of 30 days, bean following maize. The performance of bean genotypes in each cropping system was assessed by phenotyping, of different traits. The results show a significant bean genotype x cropping system interaction for flowering and for seed yield. The most competitive bean varieties were taller, more vigorous, and late to maturity. Diversification of cultural systems by implementing bean maize intercropping seems to be an effective strategy in pest management, and further research will provide a basis for incorporating practical pest control schemes into intercropping systems.

Greenhouses are now one of the most effective industries in agricultural structure, used to preserve a monitored environment suitable for crop management throughout the year. The demand for tomato products is increasing year after year, providing ample opportunities for the tomato market to grow. The variety of tomato genotypes provides a gene pool for future breeding, because they may contain traits useful for the development of new varieties and hybrids with improved quantitative and qualitative characteristics. The study aimed to evaluate the performance of five indeterminate genotypes of tomato to determine their performance under greenhouse conditions. The research was conducted utilizing biological material from the Vegetable Research and Development Station in Bacau. The data collected were: number of days till appearance of the first flowers, number of days till first fruit development, date of first harvest, as well as the outer color of the immature and ripe fruit. The results of investigations on phenotype characteristics such as fruit weight, height, diameter, dry matter content, TSS, water, minerals, and titratable acidity are discussed in the paper.

The Solanaceae family comprises species present on all continents except Antarctica. They are species with different biological cycle durations and adapted to a wide range of environments. Vegetables of the Solanaceae family are not only important for human nutrition, some species are grown for ornamental purposes but also pharmaceutical purposes. Pest species cause significant losses, and many are vectors of disease. Today, many scientists focus on developing new tools to control pest populations, with promising results of use in plant protection. Therefore, the quantitative and qualitative increase in the production of vegetables from the Solanaceae family is not only dependent on environmental factors, an important role is also played by pest prevention and control activities. This is why the objective of this paper was to identify, based on the publications available in the scientific databases of the last ten years, pests from solanaceous vegetable crops from Romania and to list the most important and effective methods of biological control that can be used by producers as more sustainable forms of pest management.

To achieve high horticultural productivity, it is known that an optimal supply of irrigation water is required. Cabbage (Brassica oleracea var. capitata) has been classified as an intermediate sensitive to water stress. Also, the development of plants under drought stress can have effects on quality and productivity, so it is necessary to use water efficiently when it comes to cabbage crops. Also, many studies show that the early effects of stress against plants can be compensated by an optimal supply of water in the growth stages. This review paper collected the latest information from the literature on cabbage water requirements, listing the most effective irrigation methods that lead to water efficiency in crops and irrigation programming to have the best cabbage production in the field.
