چکیده
KOCAQALISKAN I., DEMIR Y. & KABAR, K. 1995. A study on polyphenol oxidase activity during seed germination. Phyton (Horn, Austria) 35 (1): 37-43. English with German summary. In this work, polphenol oxidase (PPO) activities, when used four different substrates (dopa,catechol,caffeic acid, tyrosine) oxidizing activities, during seed germination of six different plants were studied in the embryos and food tissues of the seeds depending on time. It was found that during germination, PPO activities of seeds, did not show similar fate but the activities in embryos were higher than in food reserve tissues. Dopa-oxidizing enzyme had the highest activity in general. Relation between seed germination and PPO activity was discussed in point of respiration.

Excess boron reduces polyphenol oxidase activities in embryo and endosperm of maize seed during germination.
The effects of increasing concentrations of boron (0, 0.1, 1, 10 and 20 mM) as boric acid on the rate of germination and polyphenol oxidase activities in embryo and endosperm tissues of maize seeds (Zea mays L. cv. Arifiye) were studied. The germination percentage of maize seeds was not affected by boron concentrations up to 10 mM, and decreased by 20 mM. Distilled water and lower boron concent...

Effects of accelerated aging and seed priming treatments were studied on milk thistle seeds during germination process. Experiment was performed in a factorial based on Complete Randomized Design (CRD). Treatments were Salicylic acid concentrations (0, 500, 1000, 1500 and 2000 ppm) and accelerated aging for (0, 48, 96 and 144 hours under 45 °C and 95% humidity) with three replications. Our ...
متن کاملBiochemical and Physiological Studies on the Effects of Senescence Leaves of Populus deltoides on Triticum vulgare
Triticum vulgare (Wheat) based products are the major dietary source of food in developing countries. In India, it grows in association with boundary plantations of Populus deltoids (poplar). During winter, poplar enters in dormancy which cause a heavy leaf fall at the time of wheat seed germination. Large number of poplar senescence leaves may adversely affect the wheat. Therefore, the present...
متن کاملEvaluation of some physiological and biochemical characteristics of bread wheat (Triticum aestivum L.) genotypes under salinity stress
Since about 20% of the world's arable land and 50% of productions in the world are subject to salinity stress, it affects all stages of plant life from germination to seed production. The aim of this study was to investigate the effect of salinity stress on physiological and biochemical characteristics of some wheat cultivars. For this purpose, a factorial experiment was conducted in a complete...
