“…The treatment with higher concentration of CO2 (800ppm) and lower electrical conductivity in irrigation water (EC = 1dS / m) presented the highest average for the leaf area, a result different from that obtained by Rezende et al (2002). These authors observed that wellirrigated pepper plants had a lower leaf area when cultivated in an environment with higher CO2 concentration.…”

ABSTRACT:The goal of this study was to evaluate the performance of the mini watermelon plant under salinity and different levels of atmospheric CO2 concentration. The experiment was carried out at the National Center of Agricultural Informatics Research (CNPTIA -Centro Nacional de Pesquisa de Informática Agropecuária) in two different growth chambers. In the first growth chamber, the mini watermelon plants were irrigated with saline water at two different levels of electrical conductivity (ECw = 1 and 5 dS.m-1) and with an increase in the atmospheric CO2 concentration to 800ppm. In the second growth chamber, the mini watermelon plants were irrigated with saline water as previously described and with the atmospheric CO2 concentration at 400ppm.The increase of CO2 concentration provided an increase of both size and mass of the fruits, even in plants under salt stress. Thus, the results demonstrate that the increase of the atmospheric CO2 concentration provides a greater development of fruits of the mini watermelon and it can be used to improve the production even under salt stress caused by irrigation water.

“…Dentre estas tecnologias tem-se o uso do dióxido de carbono (CO 2 ) aplicado via irrigação, com o objetivo de maximizar a produtividade (Paula et al, 2011), melhorar a qualidade de frutos e reduzir os custos de produção (Furlan et al, 2002). A falta de informação sobre o efeito da aplicação de CO 2 na cultura da pimenta tem limitado a utilização desta técnica, sendo necessários estudos para determinar as doses de CO 2 mais adequadas para otimizar seu cultivo, em ambiente protegido.…”

Concentration of capsaicinoids in Tabasco pepper with doses of CO 2 applied via irrigationThe study was performed to evaluate the effects of different doses of carbon dioxide (CO 2 ), applied through drip irrigation in determining the concentration of capsaicin and dihydrocapsaicin in the fruits of hot pepper cv. Tabasco (Capsicum frutescens). We aimed to obtain hotter fruits and greater production of these substances for the market of spicy sauces. The experimental design was a randomized block with 4 treatments and 8 replications. Twenty pepper fruits were collected at full maturity, red colored, before the start of wilting, totaling 12 samples. For each sample, two replications of capsaicin and dihydrocapsaicin were analyzed. Analyses were performed by liquid chromatography with ultraviolet detection in CROMA in USP-São Carlos. The concentration of capsaicin in fruits reduced as the applied concentration of CO 2 increased, up to a minimum value of 297 mg/kg of fruits for 123.8 g CO 2 /L. The same behavior was observed in relation to dihydrocapsaicin, with a minimum of 108.46 mg/kg of fruits for 123.8 g CO 2 /L. This means that the higher the CO 2 concentration applied via drip irrigation water, the lower the analyzed capsaicinoids concentration on fruit. However, since productivity increases with increasing CO 2 doses, the total yield of these substances per plant was higher, even though it did not provide an increase in the concentration of these capsaicinoids in fruits.

“…Pinto et al (2001) notaram aumento de 21,4% em produtividade, quando aplicado CO 2 , via irrigação, no meloeiro. A aplicação de CO 2 na cultura do pimentão em ambiente protegido, para elevar a concentração da atmosfera a 800 µmol de CO 2 mol -1 , possibilitou maior produção de frutos (Furlan et al, 2002). Segundo os autores, este resultado se deve à maior produção de carboidratos pela planta uma vez que o enriquecimento do ambiente com CO 2 promove maior eficiência fotossintética; no entanto, Storlie & Heckman (1996) aplicando as doses de CO 2 1,2 g L -1 , 0,80 g L -1 e 0,39 g L -1 na água de irrigação na cultura do pimentão, não encontraram aumento na produção de frutos comerciais.…”

RESUMOEstudaram-se os efeitos da aplicação de CO 2 , via água de irrigação, e da enxertia do tomateiro no transporte de 15 N e na produção do tomateiro. Os tratamentos foram arranjados em delineamento inteiramente ao acaso no esquema fatorial 2 x 2 (com e sem CO 2 na água de irrigação e tomateiro enxertado e pé-franco). A injeção do CO 2 na água iniciou-se aos 34 dias após o transplante das mudas (DAT) e se prolongou em todas as irrigações. A aplicação do sulfato de amônio com abundância em átomos de 15 N de 3,13% nas plantas destinadas à análise foi feita aos 45 DAT quando as plantas estavam em plena frutificação. Após 14 dias da aplicação do fertilizante ( 15 N) as plantas foram colhidas, lavadas, secadas e enviadas ao laboratório, para análise do 15 N nos seus tecidos. Os resultados demonstraram que o CO 2 e a enxertia não alteraram o transporte de 15 N na planta. A produção de frutos comerciais foi maior quando se aplicou CO 2 na água. Palavras-chave:Lycopersicon esculentum Mill, dióxido de carbono, cultivo protegido Grafting and carbonated irrigation water in transport of 15 N and in the tomato production ABSTRACTThe effects of CO 2 application through irrigation water, and of grafting in transport of 15 N and in the tomato production, were studied. These treatments were arranged in a 2 x 2 factorial scheme (with and without CO 2 in irrigation water and grafted and non-grafted tomato), in a completely randomized design, with four replications. The injection of CO 2 into the water began at 34 days after transplant of seedlings (DAT) and continued for all irrigations. The application of the sulfate of ammonium with abundance in atoms of 15 N of 3.13% in plants destined to analysis was done at 45 DAT when the plants were in the middle of fructification. After 14 days of fertilizer ( 15 N) application the plants were harvested, washed, dried and sent for analysis of 15 N in plant tissue. The results demonstrated that CO 2 and the grafting did not alter the transport of 15 N in the plant. The production of commercial fruits was larger when CO 2 was applied in water.
