“…When heat-tolerant fruit varieties are not an option, heat damage can be reduced by pruning the canopy to prevent direct exposure to sunlight, applying clay, calcium carbonate, or wax emulsion sprays, and scheduling irrigations to reduce heat stress. More costly methods such as shade cloth and overhead sprinkler cooling systems are commonly used in the apple and blueberry industry, where the economic consequences of heat damage are very large (Evans 2004;Lobos et al 2013;Yang and Bryla 2016). In eastern Washington State for example, overtree or microjet sprinkling has been used for evaporative cooling to enhance color formation (Iglesias et al 2000).…”

Specialty fruit production in the Pacific Northwest: adaptation strategies for a changing climate

et al. 2017

Specialty fruit crops represent a substantial portion of the value of agricultural production in the Pacific Northwest. Climate change may threaten water sources, lengthen the dry season, raise temperatures during both the winter chilling period and the growing season, and facilitate the spread of fungal diseases and insects. Such changes have the potential to substantially reduce net returns due to increased input costs and altered yields and product quality. Many management strategies that are already being used to prolong growing seasons in marginal production areas and to improve production and quality in established production regions may also be useful as adaptation strategies under a changing climate. These strategies mostly involve moderating temperatures and controlling or compensating for mismatches between phenology and seasonal weather conditions.

“…In countries such as the USA, Switzerland, Germany, Italy, and Spain, netting has been necessary to decrease damage generated by extreme climatic conditions (rain, hail, high temperatures, and excessive radiation), as those observed in Chile in recent years (Lobos et al, 2012;2013;Retamal-Salgado et al, 2015). This should affect not only environmental and soil conditions (Bastías et al, 2012b;Cowan et al, 2014), but also in the photosynthetic apparatus (Lobos et al, 2013).…”

Blueberry production under netting has increased in recent years to mitigate the adverse effects of climate change. The objective of the present study was to evaluate the effect of different radiation intensities on rabbit-eye blueberry (Vaccinium virgatum Aiton) 'Ochlockonee' photosynthetic efficiency and productive parameters. Four treatments were established: T1 (control), T2, T3, and T4 at 0%, 30%, 60%, and 90% radiation decrease (RD), respectively, with black shedding netting. The following were recorded for each treatment: environmental conditions, photosystem II (PSII) maximum quantum yield (F v /F m ), photosystem II effective quantum yield (Φ PSII ), leaf stomatal conductance (g s ), quality parameters, and fruit yield. Results showed an increase of 4.6 ºC in mean minimum temperatures for the different netting treatments, which promote development and fruit set, as well as prevent damage at temperatures near 0 ºC. The RD treatments increased Φ PSII between 175% and 325% (P < 0.05) compared to the control. It can be concluded that netting decreased soil temperature between 1 and 3 ºC and increased minimum temperatures between 1 and 6 ºC, which promoted plant development and decreased frost damage during flowering and fruit development. Current direct radiation levels over 1000 µmol m -2 s -1 in V. virgatum inhibited productivity in T1. Netting decreased the degree of photoinhibition and increased photosystem II photochemical efficiency throughout the day, and T4 and T3 exhibited the highest efficiency.

“…Since the solar radiation has decisive importance in all plant vital processes such as photosynthesis, respiration, photoperiod, tissue growth and flowering, among others, a correct choice for protected environment cover material is a crucial issue for plant development (SAPOUNAS et al, 2010). Therefore, spawning suitable weather conditions inside protected environments may be obtained by several techniques, in which the most economical are those that employ use and combination of different types of roofing materials (GUISELINI et al 2010;LOBOS, et al 2013). …”

Effects of light intensity modification by reflective aluminized screenhouse on sweet pepper growth and yield

2014

Sweet pepper is one of the ten most consumed vegetables in world. Although it develops better under protected environment, the cultivation in tropical countries is practiced in open field due greenhouse structure higher costs. Unfortunately, such practice has compromised the crop to reach either best yield or fruit quality. Since production and cost are the most important criteria for agricultural production, we aimed to evaluate reflective aluminized polypropylene shading net influence on sweet pepper (Capsicum annuum L.) growth and production as intermediary alternative for low/middle income producers from Brazilian tropical regions. Sweet pepper Magali R hybrid was cultivated in two environments: FC -field conditions (control) and RS -reflective shading net with 40% shading rate. RS caused reductions in incident solar radiation (SR) and photosynthetically active radiation (PAR) on the amount of 46.3% and 48.3%, respectively. There were no significant changes in temperature and relative humidity recorded for the two environments. In addition, RS allowed best use efficiency of photosynthetically active radiation since it promoted higher values of plant height, leaf number and area index than those reached on FC on the amount of 29%, 22% and 80 %, respectively. Similarly, plants grown under RS showed higher yield and marketable fruits and promoted less loses by sunscald. KEYWORDS:Capsicum annuum L., shading, photosynthetically active radiation, solar radiation use efficiency. EFEITOS DE MODIFICAÇÕES NA INTENSIDADE LUMINOSA POR TELAS REFLEXIVAS NO CRESCIMENTO E PRODUÇÃO DE PIMENTÕESRESUMO: O pimentão figura entre as dez olerícolas mais consumidas em todo o mundo. Embora, ele se desenvolva melhor sob ambiente protegido, seu cultivo, no Brasil, ainda é realizado principalmente sob condições de campo aberto, devido aos altos custos das estruturas fechadas. Infelizmente, tal prática tem comprometido o alcance de melhores rendimento e qualidade dos frutos. Uma vez que a produção e os custos são os critérios mais importantes na produção agrícola, o presente estudo teve como objetivo avaliar a influência de telado de polipropileno aluminizado reflexivo no crescimento e na produção de pimentão (Capsicum annuum L.) como alternativa intermediária para produtores de baixa / média renda das regiões tropicais brasileiras. Pimentão híbrido Magali R foi cultivado em dois ambientes: FC -condições de campo (testemunha) e RStelado reflexivo com 40% de taxa de sombreamento. A tela reflexiva causou reduções na radiação solar incidente (SR) e na radiação fotossinteticamente ativa (PAR) na ordem de 46,3% e 48,3%, respectivamente. Não houve mudanças significativas na temperatura e na umidade relativa do ar registradas para os dois ambientes. O RS permitiu melhor eficiência na utilização da radiação fotossinteticamente ativa, uma vez que promoveu maiores valores de massa por planta, número de folhas e índice de área foliar que em FC na ordem de 29%, 22% e 80%, respectivamente. Da mesma forma, as plantas crescidas sob RS alcanç...
