Seed dormancy of Ochradenus baccatus (Resedaceae), a shrubby species from Arabian desert regions

Infra-Specific Genetic Diversity of Ochradenus Baccatus Delile, a Gynodioecious Species in Egyptian Flora

Ochradenus Delile is a small genus of 6-9 species within family Resedaceae. In Egypt, it is only represented by the gynodioecious Ochradenus baccatus Delile, the most widespread species across the entire range of the genus. Within Egypt, field populations and herbarium specimens of O.baccatus showed vast morphological and gender diversity within and between different populations even in the sam...

Synseed Production for Storage and Conservation of Ochradenus Baccatus Delile

Ochradenus baccatus is a medicinal plant of high value, spread over sandy and stony places of Kingdom of Saudi Arabia and most of the desert regions of Egypt. This species contains several flavanoids and specific constituents which are important as these have already been effectively used in lowering cholesterol in the blood of rats and high inhibition potential of the malarial parasite (Plasmo...

A STUDY ON COMPARISON OF SEED DORMANCY AND GERMINATION IN THREE SPECIES OF DODDER

Alleviation of Seed Dormancy in the Desert Forb Zygophyllum simplex L. from Pakistan

Zygophyllum simplex L. is a succulent annual that grows on the coastal and inland saline flats around Karachi, Pakistan. The seeds are moderately salt tolerant during germination. Germination of Zygophyllum simplex seeds under various salinity, proline, betaine, GA and kinetin treatments was determined. Proline (0±1 and 1 m) and betaine (0±1 and 1 m) alleviated the innate dormancy of seeds, a...

A STUDY ON SEED DORMANCY AND GERMINATION IN TEN SPECIES OF GRASS WEEDS

       Seed dormancy has an important role in resistance and survival mechanisms of plants. Finding of some information about the range of primary dormancy and effective factors in dormancy breaking and optimal conditions of seed germination are necessary for weed control and other research purposes.  In this research, the seeds of 10 species of grass weeds in Tehran province fields (Echinocloa...
