Carbohydrate Compositions and Peroxidase Activity in Ungerminated, Cotyledon and Embryo Tissues of Vigna unguiculata L. Walp Seed Grown Under Stress Temperatures
Shahidul Islam, R. Carvajal R. Carmen and Jr. James O. Garner

Abstract:
Twenty five cultivars were screened for germination at low (10°C), moderate (30°C) and at stress (40°C) temperatures. Three cultivars were chosen such as Texas Cream 40 was able to germinate at very high and low temperatures. Black Crowder demonstrated acceptable germination at high temperatures but negatively affected at low temperature. The main sugars present in cowpea seed were sucrose, raffinose and stachyose. Sugar contents were affected by cultivar, type of tissue and temperature. Sucrose contents were higher in embryo tissue of cultivars with low percent germination and reduced in the cultivar with higher percent germination suggesting the use of sucrose for germination. Sucrose decreased greatly at 30°C and increased again at 40°C. Raffinose and stachyose contents were higher in ungerminated seed. In germinated seed, raffinose and stachyose contents were found only in cotyledon tissues at 10°C. Peroxidase activities was affected by cultivars, type of tissue and temperature. The highest peroxidase activity was found at low temperature (10°C) in embryo tissue of the cultivar with the highest germination. High peroxidase activity was related to ability of seed to germinate at low temperature.

anuj k. ahlavat:
the paper is good enough to increase the knowledge about biochemical status of cotyledons and embryo during germination.
