“…The assessment of the kinetics of fluorescence emission of chlorophyll a permits calculation of the fluorescence parameters which characterize the operation of the photosynthetic apparatus (Yusuf et al, 2010). This assessment can be described using the JIP test (Strasser and Strasser, 1995;Tsimilli-Michael and Strasser, 2008), quantifying the energy flow that passes by the photosystems and assessing the photosynthetic performance of plants (Strasser and Strasser, 1995;Strasser et al, 2004;Tsimilli-Michael and Strasser, 2008).…”

-The objective of this work was to investigate the injuries caused to the photosynthetic apparatus of three types of rice exposed to application of imidazolinone group herbicides. Two experiments were conducted using herbicides Imazethapyr+imazapic and Imazapyr+imazapic, in a split-plot experimental design, and a 3 x 3 factorial, with six replications. The first factor (A) consisted of the herbicide rates 0, 100 e 200 g ha -1 of Imazethapyr+imazapic and 0, 140 e 280 g ha -1 of Imazapyr+imazapic; factor B consisted of type of rice (cv. Puitá Inta CL, sensitive red rice ecotype and red rice ecotype with suspected herbicide tolerance to Imidazolinone). Chlorophyll a fluorescence parameters were evaluated in plants at 30 days after herbicide application, using a portable fluorometer (HandyPEA, Hanstech). The photosynthetic metabolism of cv. Puitá Inta CL was found to tolerate commercial dosages of both herbicides. High sensitivity to the herbicides was observed for the sensitive red rice ecotype, while the photosynthetic apparatus of red rice ecotype with suspected herbicide tolerance showed high tolerance to both herbicides applied at rates higher than the commercial rate. The application of chemical herbicides of the imidazolinone group on rice plants causes changes in the photosynthetic metabolism of plants, detected by evaluating the emission of transient chlorophyll a fluorescence. This method can be useful in helping detect resistance and/or tolerance of red rice plants to herbicides of the imidazolinone group.Keywords: ALS-inhibitors, Oryza sativa, photosystems, JIP-test.

“…Detailed information can be obtained through fluorescence on the structure, energy distribution and function of the photosynthesis operation, especially for PSII (Strasser et al, 2000). But fluorescence data can be better interpreted using the assessor test, the JIP-Test (Strasser and Strasser, 1995). By using the non-modulated fluorimeter Strasser and Strasser (1995), an optimized interpretations of fast fluorescence kinetics (F 0 =50ms; Fj=2ms and Fi=30ms) that lie between the two extremes of the fluorescence intensity (F 0 =50µs and Fm = 300ms) can be obtained.…”

The Portable Chlorophyll Meter (PCM) is used to estimate the total chlorophyll and leaf nitrogen content of various species. Since there is a relationship between the chlorophyll concentration and the photochemical efficiency, a relationship can also be established between the PCM readings and some fluorescence variables to provide information on photosystem II (PSII) structure and activity. Papaya (Carica papaya L.) plants ['Sunrise Solo' (leaves with intense green coloring) and 'Golden' cultivars (leaves with yellowgreen coloring) were grown in a greenhouse with 30% interception of photosynthetically active photon flux density. The plants were cultivated in 15L plastics pots. Ninety to 100 days after planting the older leaves turned yellow and the chlorophyll fluorescence variables and PCM readings were measured. At low PCM values (less than 30 to 'Sunrise Solo' and less than 20 to 'Golden') the PSII structure and activity were damaged, which is likely related to a reduction in the numbers of active reaction centers (RC/CS 0 ). At higher PCM values the chlorophyll a fluorescence variables (ABS/RC, DI 0 /RC, TR 0 /CS 0 e ET 0 /CS 0 ) that are related to PSII structure and activity PSII were not responsive. These results indicated that the effects of chlorophyll content measured by PCM on the photochemical phase of photosynthesis evaluated by chlorophyll fluorescence occur after the degradation of chlorophyll molecules is initiated. In papaya the Portable Chlorophyll Meter (SPAD-502) was shown to be suitable for diagnosis of PSII energy distribution under N stress and senescence.

Physiological changes after application of silicon on cocoa and its influence on aphid preferenceThe physiological and biochemical aspects influenced by silicon and that influence reactions of resistance to pests in cocoa are still poorly understood. The aim of this research was to evaluate the effects of silicon application on photosynthesis, the leaf content of total soluble phenols and preference of Toxoptera aurantii in cocoa genotypes. The experiment was conducted in a greenhouse in a randomized block design with four replications in a factorial 3 x 3, consisting of three genotypes (TSH 1188, CCN 51 and Catongo), two doses of potassium silicate (3 and 6 mL L -1 ) Alterações fisiológicas após aplicação de silício em cacau e sua influência na preferência por pulgões 1Os aspectos fisiológicos e bioquímicos influenciados pelo silício e que condicionam reações de resistência a pragas no cacaueiro ainda são pouco conhecidos. O objetivo deste experimento foi avaliar os efeitos da aplicação de silício sobre a fotossíntese, sobre o teor foliar de fenóis solúveis totais e a sua influência na preferência de Toxoptera aurantii em genótipos de cacau. O experimento foi conduzido em casa de vegetação, no delineamento de blocos casualizados, com quatro repetições, em arranjo fatorial 3 x 3, constituído por três genótipos (TSH 1188, CCN 51 e Catongo), duas doses de silicato de potássio (3 e 6 mL L -1 ), aplicadas por via foliar e um controle pulverizado somente com água. Foram realizadas avaliações das trocas gasosas, da fluorescência da clorofila a e do teor de compostos fenólicos foliar, além de um teste de preferência com chance de livre escolha com T. aurantii. Os genótipos TSH 1188 e CCN 51 apresentam maior eficiência fotoquímica e fotossintética, comparados com o Catongo. Independentemente do genótipo, a aplicação de silicato de potássio não alterou o índice de desempenho das plantas (PI ABS e PI TOTAL ); no entanto, a dose 3 mL L -1 aumentou a fotossíntese líquida e o teor de fenóis solúveis totais. A dose 6 mL L -1 reduziu a preferência de T. aurantii pelas folhas do genótipo TSH 1188. A aplicação de silicato de potássio é promissora no aumento da resistência do cacaueiro a T. aurantii.
