“…ADAMS et al (2001) indicated that an increase in greenhouse temperature promotes growth, flowering and fruit production in tomato (Lycopersicum esculentum L.), and hinders attacks by pests and diseases (RODRÍGUEZ et al, 2011). Conversely, in October the average relative humidity was lower in the greenhouse with respect to the field, due to the higher temperature under the plastic cover (BURIOL et al, 2000).…”

Physalis ixocarpa (husk tomato) is traditionally cultivated in Mexico, and nowadays the yield is low. In this study, four cultivars of husk tomato were evaluated, under greenhouse and field conditions. It was carried out a split-plot experimental design in a 4x2 factorial arrangement. The large plot was the growth conditions and the small plot was the variety. The microclimate, soil and yield variables were recorded. In the field, the Integrated Photosynthetic Active Radiation (IPAR) was higher 12mol m-2 d-1 than in the greenhouse. The average temperature was slightly higher 1.18°C in the greenhouse and the average relative humidity was slightly higher 0.89% in the field. Plants grown in the greenhouse had lower negative values for the matric potential of the soil. Water consumption and water use efficiency were 10.31 and 53.43% higher in the greenhouse that in the field, respectively. The number of fruits and yield increased significantly in all varieties grown under greenhouse conditions.

“…The disadvantage for cultivation under covers is that some covers can reduce 30–40% transmission of photosynthetically active radiation (PAR) [ 66 , 69 ]. Reduction in PAR and changes in the spectral quality of light received by plants can reduce the photosynthetic rate and trigger shade-avoidance responses, causing shoot elongation [ 70 ], all of which adversely affect yield and fruit quality [ 69 , 71 ]. Furthermore, crop covers that contain UV stabilizers or absorbers to reduce polyethylene degradation block plant exposure to UV.…”

Blueberry, hailed as an antioxidant superfood, is the fruit of small shrubs in the genus Vaccinium (family Ericaceae). The fruits are a rich source of vitamins, minerals and antioxidants such as flavonoids and phenolic acids. The antioxidative and anti-inflammatory activities derived from the polyphenolic compounds, particularly from the abundantly present anthocyanin pigment, have been highlighted as the major contributing factor to the health-benefitting properties of blueberry. In recent years, blueberry cultivation under polytunnels has expanded, with plastic covers designed to offer protection of crop and fruit yield from suboptimal environmental conditions and birds. An important consideration is that the covers reduce photosynthetically active radiation (PAR) and filter out ultraviolet (UV) radiation that is critical for the fruit’s bioactive composition. Blueberry fruits grown under covers have been reported to have reduced antioxidant capacity as compared to fruits from open fields. In addition to light, abiotic stresses such as salinity, water deficit, and low temperature trigger accumulation of antioxidants. We highlight in this review how interventions such as light-emitting diodes (LEDs), photo-selective films, and exposure of plants to mild stresses, alongside developing new varieties with desired traits, could be used to optimise the nutritional quality, particularly the content of polyphenols, of blueberry grown under covers.

“…Cultivation in a protected environment presents several advantages when compared to open cultivation since it provides through temperature control, humidity, water availability and CO 2 , greater physiological comfort to the crop and helps to ensure better plant quality and productivity (Carvalho et al, 2018). The correct irrigation management and the monitoring of climatic variables are essential in this cultivation technique, in which the only source of water is supplied from irrigation (Holcman et al, 2015;Girardi et al, 2016).…”

The determination of the crop coefficient (Kc) is vital since, although gerbera cultivation is constantly expanding, there is little research on the evapotranspiration of the crop cultivated under a protected environment to obtain the correct irrigation management. The objective of this work was to evaluate the evapotranspiration and crop coefficients of cut gerbera, cultivated in protected environment. The reference evapotranspiration (ETo) and crop evapotranspiration (ETc) were obtained through the Penman and weighing lysimetry methods, respectively. The experimental design used was completely randomized, consisting of five irrigation treatments (120, 100, 80, 60, and 40% of the water retention capacity), with ten replicates each, totalizing 50 experimental units. The Kc was evaluated using the irrigation lamina that presented the highest production of floral stems among the tested treatments, obtained through the relation between ETc and ETo. The mean of the crop coefficient ranged from 0.72 in vegetative period I, 0.81 in vegetative period II, 0.85 in flowering I, 0.89 in full flowering II, 1.33 in full flowering III, and 1.06 in end of the flowering I. The water consumption for the cut gerbera crop in the treatments with water availability ranged from 225.87 to 523.58 mm. Therefore, the crop coefficients proposed for the different phenological stages of the gerbera were efficient for irrigation management.
