the present study is based on the investigation of a soil hyphomyces, paecilomyces lilacinus, an opportunistic bio-control agent, in controlling root-knot nematode meloidogyne javanica on tomato in greenhouse conditions. p. lilacinus, effectively promoted the growth of plants inoculated with m. javanica by suppressing its pathogenesis as root galling by the nematode and egg mass production was ...

The growth of medicinal plants and biosynthesis of secondary metabolites is influenced by plant growth regulators. In this study we investigated influence offour levels (0, 500, 1000, and 1500 mg l-1) of2-chloroethyltrimethylammonium chloride (Cycocel), a plant growth retardant, on growth parameters and some biochemical parameters of cannabis plants. Cycocel only at 500 mg l-1 decreased shoot l...

introduction growth analysis has been widely used in breeding programs to identify the important plant developmental phases and components related to higher yield under a particular set of environmental conditions. castor bean (ricinus communis l.) is an important commercial crop. castor oil based by products is used in manufacturing of several commercially important commodities like surfactant...

Objective: Salt stress is a world-wide problem and soil salinity is common in arid and semi-arid regions. This study was undertaken to investigate salt tolerance in Salsola orientalis in laboratory and natural conditions and recognize the mechanisms that allow it to tolerate these conditions. Methods: This study had two parts of greenhouse and natural habitats. The treatment s...

water and nutrient absorption by plants is one of the most conspicuous factors which seriously affect plant productivity. improving physical properties of soilless media and their water retaining capacity can improve plant's nutrient absorption, growth and subsequent yield. in this study, we tried to improve plant nutrient absorption through incorporation of hydrogel into growth media and ...

The longitudinal arrangement of root systems, as well length, diameter, and hairs are referred to architecture. Plant system plays key role in regulating plant growth development. Root tuber crops (RTCs) that vegetatively propagated offer food security for enormous populations. morphology is affected by soil, climatic, factors. Parameters normally used express distributions number, weight, surf...
