Chemical thinning of apple fruitlets is an important practice as it reduces the natural fruit load and, therefore, increases the size of the final fruit for commercial markets.

The Cupric Ion as an Inhibitor of Photosynthetic Electron Transport in Isolated Chloroplasts [PDF]
Strong inhibition of uncoupled photosynthetic electron transport by Cu(2+) in isolated spinach chloroplasts was observed by measuring changes in O(2) concentration in the reaction medium. Inhibition was dependent not only on the concentration of the inhibitor, but also on the ratio of chlorophyll to inhibitor.

Different concentrations of ethylene inhibitor AVG (aminoethoxyvinylglycine) and promoter ACC (1-aminocylopropane-1-carboxylic acid) were sprayed to seedlings of soybean cultivar Tiefeng 31, and their effects on photosynthesis and CO2 response curves ...

Arsenic (As) stress provokes various toxic effects in plants that disturbs its photosynthetic potential and hampers growth. Ethylene and selenium (Se) have shown regulatory interaction in plants for metal tolerance; however, their synergism in As ...

Hydrostatic Pressure: A Reversible Inhibitor of Primary Photosynthetic Processes
Abstract Primary photosynthetic processes under pressures of up to 1300 atm were studied by means of chlorophyll fluorescence induction (Kautsky-effect) and compared to simultaneous oxygen exchange transients determined polarographically. Chlorophyll fluorescence induction was affected by increased hydrostatic pressure in three distinct

On a new inhibitor of photosynthetic electron-transport in isolated chloroplasts
A halogenated benzoquinone has been found to inhibit the photosynthetic electron transport system in isolated chloroplasts. 2·10-6ᴍ of dibromo-thymoquinone inhibit the Hill- reaction with NADP, methylviologen or anthraquinone to 100%, but do not effect the photoreduction of NADP at the expense of an artificial electron donor.
