PHOTOSYNTHETIC APPARATUS OF 'MIAGAVA-WASE' DWARF MANDARIN CULTIVARS, APPLYING THE TREATMENTS WITH GROWTH REGULATORS

Response of Germination and Seedling Growth of Pepper cultivars to Seed Priming by Plant Growth Regulators

In order to study the germination and growth of pepper seeds, a factorial experiment based on a completely randomized design with three replications was conducted. The first factor was consisting of five cultivars of pepper (Marquiza, Cadia, California Wonder, California Wonder 310 and California Wonder 300) and the second factor was gibberellic acid with three levels (0 as control, 250 and 500...

Regulation of the photosynthetic apparatus under fluctuating growth light.

Safe and efficient conversion of solar energy to metabolic energy by plants is based on tightly inter-regulated transfer of excitation energy, electrons and protons in the photosynthetic machinery according to the availability of light energy, as well as the needs and restrictions of metabolism itself. Plants have mechanisms to enhance the capture of energy when light is limited for growth and ...

Effect of Plant Growth Regulators on Soluble Carbohydrates, Photosynthetic Pigments and Chlorophyll Fluorescence of Sirvan and Homa Wheat Cultivars in Rainfed and Irrigation Conditions

Adverse environmental conditions cause stress in plants, and some plant growth regulators (PGR’s) improve plant tolerance to these undesirable conditions. In order to study the effect of gibberellin, cytokinin and cycocle on some physiological traits of two wheat cultivars under different irrigation regimes, a study was conducted as a split-split plot experiment based on a randomized complete b...

Response of photosynthetic apparatus to moderate high temperature in contrasting wheat cultivars at different oxygen concentrations.

The photosynthetic responses to moderately high temperatures (38 degrees C, imposed at 21% or 2% O(2) in air and 1500 mumol m(-2) s(-1)) were compared in wheat (Triticum aestivum L.) cultivars grown in northern regions of Ukraine and expected to be relatively sensitive to high temperatures ('North' cultivars) and in cultivars grown in southern regions and expected to be relatively heat-tolerant...
