This book aims to define the ecological aspects (soil conditions and factors affecting seed germination) of some selected parasitic flowering plants e.g. Cuscuta and Orobanche. The host-parasite interactions among some flowering plants will be discussed. Soil salinity was found to be an important factor controlling the distribution of parasites. However, Cistanche was found to be less sensitive to soil salinity as indicated by its ability to infect plants living in soil with relatively high salinity. Other soil chemical properties (such as calcium and magnesium contents) played a marginal...

The book is concerning the ecology of Plantago major L. including the distribution, associated plant species, phenotypic plasticity and chemical composition in twenty sites at Damietta, Egypt. Plantago major has a wide ecological amplitude, it grown in soil with a wide range of salinity and nutrients. This weed is forced to show a considerable phenotypic plasticity. The obtained results will be useful for the optimum management of this medicinal weed.
