Allelopathy in aquatic macrophytes: Effects on growth and physiology of phytoplanktons

The present review discussed allelophatic effects of aquatic macrophytes on phytoplankton with emphasis on growth and physiology; and also indicates implication for control of invasive aquatic macrophyte and phytoplankton species. In view of the fact, inhibition of phytoplankton by allelochemicals released by macrophytes is supposed to be one of the mechanisms that contribute to stabilisation of clear-water states in...

Propagation and growth from cultured single node explants of rosa (Rosa miniature)

Roses are one of the world's most important ornamentals for a long time and are most often used for ornamental, medicinal and aromatic purposes. A method for the proliferation and growth of rose (Rosa miniature) was developed. First to seventh nodal explants from young healthy shoots were excised and cultured on basal medium of Murashige and Skoog (1962, MS) containing several concentrations of Benzyl amino...

Effect of time of harvest on physiological maturity and kenaf (Hibiscus canabinus) seed quality

Field experiments were carried out between July and December 2010 and 2011 at research station of the Institute of Agricultural Research and Training, Obafemi Awolowo University, Moor Plantation, Ibadan, to determine the effects of time of harvesting on kenaf seed physiological maturity and quality. Kenaf seed of 10 genotypes were collected at seven harvesting periods. Seeds were harvested at 5 day interval from 15 to...
