Cultivation Systems, Light Intensity, and Their Influence on Yield and Fruit Quality Parameters of Tomatoes

Abstract

The yield and fruit quality parameters of tomatoes are influenced by environmental conditions, and cultivation systems play an important role in improving quality, apart from breeding. We examined five breeding lines and one cultivar in five cultivation systems for yield and fruit quality parameters. The cultivation systems include a single-glazed greenhouse with and without supplementary LED interlighting; a double-glazed greenhouse with and without supplementary LED interlighting; and an organic cultivation system on the field with a rainout shelter. Plants and fruits grown in the double glazing system showed significantly lower values for plant height, yield, DM, TSS, fructose, glucose, antioxidant capacity (DPPH, TEAC), TPC, calcium, phosphorus, and manganese content than in the single-glazed greenhouse, which can be explained by the lower light transmittance. However, it could be seen that the additional LED interlighting could lower the negative effect on yield and quality traits due to double glazing.

The Impact of Genotype and Controlled Environment Cultivation Parameters on Tomato-Leaf-Derived Exosome-like Nanoparticle Yield and Properties

“…However, both high and low temperatures remarkably affected the PDEN protein content, particle concentration, and RNR content, and reduced PDEN sample uniformity by affecting the size distribution of the nanoparticles. Investigated non-optimal cultivation parameters, especially lighting intensity, are in agreement with findings by other authors [39,40] in showing enhanced tomato-leaf antioxidative properties; however, this higher DPPH and ABTS free-radical scavenging activity was not transferred to the PDEN preparations. Despite this, an inhibitory effect of PDEN preparations on HaCaT keratinocyte metabolic activity, compared with the control, was observed, and the highest impact (lowest metabolic activity; 15% lower compared to control) was determined for PDEN preparations obtained from tomato leaves cultivated under optimal conditions.…”

From the First to Third Generation of Neonicotinoids: Implication for Saving the Loss of Fruit Quality and Flavor by Pesticide Applications

“…Tomato fruit flavor is composed of soluble sugars, organic acids, amino acids, and volatile compounds . Several strategies to increase tomato fruit flavor have been reported: (1) reintroduction of high flavor traits which were searched in the genetic pool of wild tomato relatives into the commercial cultivars; (2) grafting tomatoes into rootstocks to increase tomato fruits’ volatile abundance; (3) changing the harvested stage from the mature green stage to mature red stage; (4) developing methods to improve tomato fruit quality during postharvest storage; and (5) optimizing tomato plant cultivation conditions, such as light intensity, irrigation methods, and N fertilization levels . However, there are few reports about the influence on tomato flavor of pesticide applications.…”
