Abstract In vitro cultivation is a technique with wide application for micropropagation. However, each species has specific mineral needs this type of cultivation. The objective was to assess the impacts saline solution culture medium on performance photosynthetic apparatus and growth Bromelia antiacantha during in cultivation, thus elucidate mitigation nutritional imbalance that can interfere ...

Manganese (Mn) excess is a major abiotic stress for plant growth. In the present study, we investigated effects of Mn on photosynthesis in Ligustrum lucidum and Melia azedarach leaves using chlorophyll fluorescence transients. Both species were exposed to two concentrations (0.5 1 mmol) 10 30 d. Results showed that significantly inhibited photosynthesis. With increase concentration time, inhibi...

As a typical warm-season grass, Bermudagrass [Cynodon dactylon (L).Pers.] is widely applied in turf systems and animal husbandry. However, cold temperature is a key factor limiting resource utilization for Bermudagrass. Therefore, it is relevant to study the mechanisms by which Burmudagrass responds to cold. Melatonin is a crucial animal and plant hormone that is responsible for plant abiotic s...

The purpose of this paper is to demonstrate the complementary utility of chlorophyll fast fluorescence OJIP transient (from 50 microns to 1s) measurements in the aerial study of rows of trees. We identify limitations in photochemical events induced by urban injuries on Platanus acerfolia L. using the JIP-test procedure. The Performance Index (PIABS) showed the largest dynamic range to character...

In order to evaluate influential mechanisms for photosynthetic processes on the yields of an intercropping system composed maize (Zea mays), Lupinus sp. and Melilotus albus, three treatments were designed conducted in southern Moravia (Czech Republic) form agronomy trials. The included sole (SM), with (ML) field melilot (MM). Zea mays monitored using several chlorophyll fluorescence techniques ...

We provide here a general introduction on chlorophyll (Chl) fluorescence, then we present our measurements fast (< 1 s) induction curves (the so-called OJIP transients) dark-adapted intact leaves of Arabidopsis thaliana, under five different light intensities [in the range ~ 500 to 3,000 µmol(photons) m‒2 s‒1] using two instruments: Handy PEA (Hansatech Instruments, UK; e...
