1. Atividade fotossintética em plantas do gênero Prunus / Photosynthetic activity in plants of the genus Prunus
O crescimento e o desenvolvimento de plantas da família das rosáceas apresentam variações dos processos fisiológicos durante o ciclo anual. Espécies vegetais que ocorrem ao longo de um ambiente heterogêneo estão sujeitas as condições de múltiplos estresses devido à variedade das condições climáticas. Nesse contexto, o estresse hídrico, por al

2. Photosynthetic activity in the rootstock of hybrid peach trees submitted to water restriction and flooding
This study aimed to evaluate the effect of flooding and water restriction (drought) on the photosynthetic activity in plants of the hybrid rootstock 'GxN-9' (Prunus dulcis Mill. × Prunus persica L. Bastsch), grown in a greenhouse. Chlorophyll fluorescence and gas exchange were analyzed in plants of approximately 12 months. The reduction of photosynthetic ac

3. Chlorophyll a fluorescence as indicative of the salt stress on Brassica napus L.
The effects of salinity stress on chlorophyll fluorescence and the growth of Brassica napus L were investigated. The chlorophyll a fluorescence transient were recorded and analyzed according to the JIP-test which can quantify PSII performance. Salt stress resulted in decreased leaf area and dry matter compared with the control treatment (0 mM NaCl). The most

4. Relationship between photochemical efficiency (JIP-Test Parameters) and portable chlorophyll meter readings in papaya plants
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
