PLANT GROWTH RESPONSES TO VESICULAR-ARBUSCULAR MYCORRHIZA

THE SYMBIOSIS EFFECT OF VESICULAR-ARBUSCULAR MYCORRHIZA ON GROWTH OF POA BULBOSA (BULBOS BLUE GRASS)

Inoculation experiments were carried out in pot culture to determine the effects of VA fungi on the growth of Poa bulbosa. In this experiment, four treatments  were  used: 1. Strile soil without  inoculation,  2. Strile soil plus inoculum, 3. Natural soil plus inoculum, and 4. Natural soil without inoculation. Inoculum was prepared from a suspension of mycorrhizal  roots of  Poa  plants (Root c...

Plant 9-lox oxylipin metabolism in response to arbuscular mycorrhiza.

The establishment of an Arbuscular Mycorrhizal symbiotic interaction (MA) is a successful strategy to substantially promote plant growth, development and fitness. Numerous studies have supported the hypothesis that plant hormones play an important role in the recognition and establishment of symbiosis. Particular attention has been devoted to jasmonic acid (JA) and its derivates, the jasmonates...

Vesicular-Arbuscular Mycorrhiza Influence Growth but Not Mineral Concentrations in Seedlings of Eight Sweetgum Families

Arbuscular Mycorrhiza Improves Substrate Hydraulic Conductivity in the Plant Available Moisture Range Under Root Growth Exclusion

Arbuscular mycorrhizal fungi (AMF) proliferate in soils and are known to affect soil structure. Although their contribution to structure is extensively investigated, the consequences of those processes for soil water extractability and transport has, so far, gained surprisingly little attention. Therefore we asked, whether AMF can affect water retention and unsaturated hydraulic conductivity un...

Production of Plant Growth-Regulating Substances by the Vesicular-Arbuscular Mycorrhizal Fungus Glomus mosseae.

Glomus mosseae, a representative species of Endogonaceae (Phycomycetes) able to form vesicular-arbuscular mycorrhiza, was investigated for phytohormone production. Spores of G. mosseae were axenically germinated in water, and the resultant mycelial growth was assayed by standard procedures for extracting plant hormones from microbial cultures. Paper partition chromatography and specific bioassa...
