speaking, do not have roots, rather they form mycorrhiza. There are seven principle types of mycorrhiza. The two most important mycorrhizas are the endomycorrhiza and ectomycorrhiza. Endomycorrhiza typically colonize herbaceous plants, shrubs, many ornamental, fruit and nut trees, vegetables and agronomic crops, and turf grasses. More than 85% of higher plants form endomycorrhizal associations....

Systemic insecticides are compounds that may be applied to plants as a foliar spray or to the soil/ growing medium as a drench or granules. These materials are absorbed by roots or into other tissues and then translocated to plant parts. This may then protect plants from damage associated with phloem-feeding insects such as the Hemipterans including aphids, whiteflies, mealybugs, and soft scale...

In recent years, extensive research has been done on phytoremediation technology, but the study on repair mechanisms and the migration path of heavy metal contaminants in woody plants is particularly rare. The object of this study was Pan Yi mine reclamation area in Huainan as an example of cadmium (Cd) content within different parts of woody plants tissue. Based on the research findings about ...

Developing new ornamental cultivars with improved floral attributes is a major goal in floriculture. Biotechnological approach together with classical breeding methods has been used to modify floral color, appearance as well as for increasing disease resistance. Transgenic strategies possess immense potential to produce novel flower phenotypes that are not found in nature. Adoption of Genetic e...

In this paper we document the role of Phormium tenax as a nurse plant in unimproved pasture. We show that for our study area the regeneration of woody species was limited solely to P. tenax clumps with 22 native and one introduced regenerating woody species present. The number of woody species and of individual woody plants regenerating within P. tenax is not correlated with distance from the e...

forest reserves are one of the most important approaches in ecosystem management in iran. in order to determine the effects of reserve management on plants diversity (woody plants and ground flora) in three zones (core zone, buffer zone, and transmission zone of chamhesar pear forest reserve), we mapped land form units. then 18 main sampling units (20×50=1000 m2) distributed randomly were chose...

Due to rapid industrialization and urbanization, environmental pollution has become a significant concern in developing countries; therefore, the main objective of the current study is to determine some of the heavy metal (HM) concentrations in the leaves of dusty miller (Cineraria maritima) and purstane (Mesembryanthemum cordifolium) in different general bus terminal along with the green space...
