Photosynthetic Activity of Four Florist Azalea Cultivars

Using an Infrared Gas Analyzer for Evaluation of Photosynthetic Activity in Some Iranian Pistachio Cultivars

Photosynthetic rates of six pistachio cultivars were studied including Ohadi, Kalleh-Ghochi, Akbari, AhmadAghaii, Rezaii Zoudras and Haratii. Measurements were done using OFF and ON shoots at different stages of fruit growth and development included: - Beginning of endocarp growth; - pith hardening; - Beginning of endosperm rapid growth; - end of embryo development; - ripening and harvesting ti...

Characterization of Four Famous Red Grapevine Cultivars

The grape berries due to containing organic acids, sugars, aromatic compounds, phenolic compounds (including anthocyanins, flavanols, flavonols, stilbenes (resveratrol)), tannins, and oil in the pulp, skin, and seed have numerous health benefits for human health. In this study, we investigated genetic and phytochemical characteristics of four famous grapevine cultivars (Shiraz, Sirch, Panje Aro...

Relationship between Chloroplast Membrane Fatty Acid Composition and Photosynthetic Response to a Chilling Temperature in Four Alfalfa Cultivars.

The photosynthetic responses of four alfalfa (Medicago sativa L.) cultivars to 10 and 22 C air temperatures were examined and the relationship between the photosynthetic response at 10 C and the fatty acid composition of the chloroplast membranes was determined. Chilling-resistant cultivars exhibited moderate reductions in photosynthesis at 10 C, compared to 22 C, and contained a significantly ...

Impact of Salicylic Acid on Phenolic Metabolism and Antioxidant Activity in Four Grape Cultivars during Cold Storage

Salicylic acid (SA) plays an important role in the regulation of plant ripening and responses to abiotic stresses. In this study, the protective effect of SA on cold stress-caused oxidative damage in grape (Vitis vinifera L.) bunches was investigated during cold storage.  Grape bunches treated with 2 mM SA and  stored at 0°C with 85-90% RH for 30 days. Samples were selected from each treatment ...
