Vegetative Multiplication

The tomatoes are valuable vegetables, with highest share in Romanian crops from protected spaces. The grafting is a vegetative multiplication method that induces or improves some qualities of the plants (vigor, resistance to soil diseases and pests, resistance to abiotic factors, quantity and quality of fruit production). The research aim has been to establish the technological stages for producing of Dutch scion and Romanian rootstock seedlings from Solanum lycopersicum L. species, to obtain some compatible phenotypes for grafting. This research has been conducted in a greenhouse of the Horting Institute Bucharest. The experience was carried out on a tomato cultivar collection consisting from a Dutch scion (‘Abellus’ F1 hybrid) and three Romanian rootstocks (‘L542’, ‘L543’, ‘L544’). The scion and rootstock diameters have been correlated for manual grafting, cutting at 45 degrees and using the method of splice in silicone tube. The technological stages for obtaining grafted tomatoes have been established for the researched genotypes. These tomato combinations have been compatible for vegetable crops in protected spaces in the south area of Romania.

Volcanic rock has been used for decades as a horticultural substrate worldwide. In Spain, the use of this material as a substrate is ancient; it was initially used in the Canary Islands because of its volcanic geological origin. At the University of Almería (Almería, Spain), three independent vegetable crops were grown under greenhouse conditions: sweet pepper, tomato, and melon. The volcanic rock came from a location in the geographic center of Spain, which facilitated logistics. Bags of volcanic rock (25 L) were used and were compared with a commercial coconut fiber substrate of an equal volume. All physical, physical–chemical, and chemical parameters of the volcanic rock were determined using European standard analytical procedures. Fertigation was applied, independently adapted to the physical, physical–chemical, and chemical characteristics of each substrate. The cultures were performed under a randomized complete block experimental design. Fertigation parameters, pollutant emissions, fruit production, and the quality of each culture were measured. The results showed that the assessed parameters of the volcanic rock substrate are not a limiting factor for its use as a horticultural substrate. The resultant production and quality were very similar among the three crops compared with a widely used commercial control. Therefore, volcanic rock emerges as a local, sustainable alternative to be used for soilless crop cultivation.

Greenhouse is widely applied to provide protection against pest and harsh environment condition and most farmers usually planted mixed crops inside. However, this system creates an isolation to pollination which responsible for fruit production. In this study, local domesticated stingless bees, Trigona (Tetragonula) laeviceps, was applied as pollinator for two crops, beans (Phaseolus vulgaris L.) and tomatoes (Solanum lycopersicum L.) planted as mixed crops inside greenhouse. The benefit of the bees was measured as pollination success and quality of the crops produced (size and weight). Tomato flowers received no visit from both wild pollinators (all was Apis cerana) and stingless bees while in bean flowers, A. cerana exhibited more and longer visits to flower than T. laeviceps albeit lower number of flowers visited. The pollination efficiency between wild pollinator and T. laeviceps for beans (both at 41%) while self pollination produced better pollination efficiency for tomatoes planted at open field (84% compared to 71%). Beans planted at open field produced better products (bigger size and heavier) while tomatoes produced lesser quality although the differences were not significant. Based on this study, T. laeviceps may applied as pollinator agent in greenhouse and for mixed crops of beans and tomatoes.

Magetan Regency is one of the leading fruit production centers (Pamelo Oranges) and vegetables in East Java.   Production of Pamelo orange as a superior product of Magetan regency, during the last 10 years tends to decrease both in terms of quantity and quality.   This is as a result of fruit fly pest attack is quite massive and viral; as well as vegetable crops that still depends on pesticide and chemical fertilizers. Quantity and quality of fruit and vegetable products are still not optimal because: 1). There are still pests and diseases that can not be controlled in an environmentally friendly manner, 2) The cultivation of pamelo and vegetable plants in Magetan regency has not been fully applied organic fertilizer intake, 3). Gardening irrigation technology still relies on rain water and semi-technical irrigation. The objective of the action research through Community Partnership Program (CPP) is to provide a touch of science and technology that is expected to accelerate the creative economic activities of the community by providing skills training based on organic materials including: 1. The utilization of yard land by planting vegetables;  2. The production soil enhancer;  3. Production of urine-based biopesticide ;  4.  Simple book keeping practice  in small-medium scale agriculture, and 5.  Production of Pamelo orange-based food. The methods used in facilitating the improvement of skills of farmers and dairy farmers joined in micro small and medium enterprises including lecture, field practice and mentoring. The result of  activities is expected to be able to: a). improve farmers skills in good plant care through integrated pest and disease control and organic based fertilization through fertigation. b). Make environmentally friendly fertilizers and pesticides independently. c). Increasing the production and quality of agricultural products. d). Innovative organic biofertilizers products.

Background: Tomato is one of the most important vegetable crops in the world due to its dietary value. Harvesting and storing of physiologically matured tomato seeds is very important to secure good quality seeds for future use in a changing climate. The objective of the study was to assess the effect of maturity stages on seed quality of two tomato accessions during cold storage. Methods: Seeds of two tomato accessions extracted at four maturity stages (i.e. initially ripe, half ripe, fully ripe and rotten) were stored at -20oC in a deep freezer for 12 months. The quality of stored seeds was measured by seed vigour and germination percentage at 3, 6, 9 and 12 months after storage. Conclusion: The study showed significant differences in seed vigour and germination percentage at 3, 6, 9 and 12 months after storage (MAS) among the maturity stages. Seeds extracted at the initially ripe stage in GH 9305 had the least vigour at 3, 6, 9 and 12 MAS. The highest reduction in seed quality during the storage period was observed in seeds extracted at the rotten stage in both accessions. Seed vigour and germination were higher in GH 9207 than GH 9305. Storage of physiologically matured tomato seeds at freezing temperature is necessary to reduce seed ageing and to maintain high seed quality.

Abstract Background Tomato (Solanum lycopersicum L.) belongs to the family Solanaceae is one of the most popular and most processed vegetable crops worldwide with a great nutritional contribution to the human diet. Though the demand for tomato products is increasing, its production is constricted by shortage of quality seeds due mainly to lack of appropriate seed extraction method. Inadequate seed extraction method also causes extensive disease epidemics. Conversely, empirical evidences are scanty on instant and latent effects of seed extraction methods. This study was therefore initiated to evaluate the effects of extraction methods on the physiological quality of seeds and seedlings of tomato. Result Results revealed that the highest germination percent (99.33 and 89.76% under laboratory and field conditions respectively) was obtained at 2% HCl for 60 minutes. Whereas, the maximum weight of 1000 seeds (4.277 g) was found at 1% of HCl for 30 minutes. Mycoflora load was maximum (36%) at fermentation for 72 hours. Yet, no mycoflora was detected from higher concentrations of HCl acid greater than 2% and time durations longer than 60 minutes. Conclusion the major seed quality parameters such as seed germination percent, seedling length, seedling fresh weight, seedling dry weight, and vigour indices were significantly higher at extraction method of 2% HCl for 60 minutes. Thus, it can be concluded that the maximum physiological seed quality and best performance of seedlings of tomato obtained from 2% HCl for 60 minutes seed extraction method of tomato.

Due to novel and more demanding consumers’ requirements, breeding of vegetable crops confronts new challenges to improve the nutritional level and overall appearance of produce. Such objectives are not easy to achieve considering the complex genetic and physiological bases. Overtime, plant breeders relied on a number of technologies and methods to achieve ever changing targets. F1 hybrid seed production allowed the exploitation of heterosis and facilitated the combination of resistance and other useful genes in a uniform outperforming variety. Mutagenesis and tissue culture techniques permitted to induce novel variation, overcome crossing barriers, and speed up the achievement of true-breeding lines. Marker-assisted selection was one of the milestones in fastening selection, starting from the early ’90s in almost all seed companies. Only recently, however, are novel omics tools and genome editing being used as cutting-edge techniques to face old and new challenges in vegetable crops, with the potential to increase the qualitative value of crop cultivation and solve malnutrition in 10 billion people over the next 30 years. In this manuscript, the evolution of breeding approaches in vegetable crops for quality is reviewed, reporting case studies in tomato (Solanum lycopersicum L.) and cauliflower (Brassica oleracea var. botrytis L.) as model systems for fleshy fruit and floral edible parts, respectively.

Abstract Japanese tomato cultivar ‘Rinka 409’ is suitable for harvesting at a fully ripe stage since it remains firm at the stage, resulting in longer shelf life. However, it is difficult to estimate the quality change because its color does not change after the fully ripe stage. For ‘Momotaro,’ we previously proposed a fluorescence-based indicator of overripening; however, its suitability for another cultivar, ‘Rinka 409’, and its relationship with temperature and quality were unclear. Therefore, in this study, we investigated the appropriateness of this fluorescence-based index for the above purposes. In 2021, 45 tomato seedlings planted in 2020 were harvested at the fully ripe stage and used for experiments. Weight loss and firmness were evaluated to determine the quality of the tomatoes. The post-harvest temperatures were set as 10, 17, and 25 °C. The results showed that the rate of weight loss increased linearly, whereas the firmness decreased exponentially. For non-destructive estimation of these properties, the excitation-emission matrix (EEM) was measured in the range of 250–460 nm and 280–750 nm for the excitation and emission, respectively. ‘Rinka 409’ showed a strong fluorescence emission at 400 nm/620 nm of the excitation/emission, respectively, regardless of days and temperature. The fluorescence intensity, as well as the firmness, decreased exponentially. Thus, a linear relationship was observed between them. The firmness of ‘Rinka 409’ can be estimated using a simpler linear regression model using this method than previous researches.
