ABSTRACT Strawberry is a crop of great economic and social importance. Its fruits are appreciated both for their flavor and nutraceutical potential. Some studies confirm that light quality influences plant physiology. Thus, the aim of this study was to investigate if changes in light spectrum, provided by low tunnels, can improve vegetative traits, as well as, production and fruit quality of strawberry. The authors used six tunnel covers (red, yellow, blue, green, transparent and opaque and one control, without cover), and two cultivars: a short photoperiod cultivar (Camarosa) and a neutral photoperiod cultivar (Albion). Experiment was evaluated in two seasons: production and plant development first; and then, post-harvest quality. Overall, Camarosa showed higher vegetative growth, lower production, and better fruit quality than Albion. Due to the complexity of physiological and biochemical responses, each trait evaluated showed a specific response to light changes. The red, blue, yellow and green covers did not show any significant improvement comparing with transparent and opaque covers. Thus, the authors suggest the use of the latter ones which have already been used commercially.

Sweet pepper (Capsicum annuum L.) is one of the main cultivated vegetable species in Hungary mostly produced under plastic tunnel by unheated technology. Sweet pepper plants could suffer high temperature and radiation during summer season. However, photoselective-shading nets can provide a new tool for light quality manipulation and support the plant development and fruit quality. The effect of shading colour nets depends on natural light conditions and other environment factors; therefore it is necessary to evaluate the shading technology. Hungarian sweet pepper variety was grown in South-East part of Hungary under plastic tunnels using different colour nets, as white, yellow, green and red, for shading in 2013. Results of trial proved that green colour shading net usually decrease the yield, while yellow and red nets can increase the yield and the fruit quality of Hungarian type sweet pepper. Growers have to care the shading intensity of the net, which should not be higher than 35-40%. Colour shading nets can be placed onto the plastic tunnels just after the planting.

ABSTRACT Watermelon farming has a high economic and social importance. In parallel, the consumers’ demand for distinctive products has led to niche markets, where mini watermelons stand out. This study aimed to assess the agronomic performance and fruit quality of mini watermelon grown in coconut husk fiber, as a function of number of stems per plant and plant density. The Smile hybrid was used, as well as a randomized block design, in a 2 x 2 factorial scheme, with eight repetitions, being the first factor the number of stems per plant (1 or 2) and the second the number of plants per pot (1 or 2). Characteristics related to yield, physiological parameters and fruit quality were assessed. Interaction between number of stems and plant density was only observed for leaf area, average fruit fresh weight, total yield and percentage of large fruits. The factors were evaluated separately for the remaining traits. Two-stemmed training systems, at a density of one plant per pot, produce the highest yield, without compromising the quality of the fruits, being, in these conditions, the most suitable method for farmers.
