Effect of Constant and Diurnally Fluctuating Temperatures on Arbuscular Mycorrhizal Fungus Infection and the Growth of Infected Asparagus (Asparagus officinalis L.) Seedlings

چکیده
Effect of constant and diurnally fluctuating temperatures on arbuscular mycorrhizal (AM) fungi [Glomus etunicatum (GE) and Gigaspora margarita (GM)] infection and the promotion of infected seedling growth through asparagus-AM fungus symbiosis were investigated. 1. At constant temperatures, spore germination rate became maximum at 25 •Ž in GE, and at 25•Ž and 30•Ž in GM. Hyphal growth was enhanced at 20•‹, 25•‹and 30•Ž in GE, and at 25•‹, 30•‹ and 35•Ž in GM.

Vesicular-arbuscular (VA) mycorrhizae improve salinity tolerance in pre-inoculation subterranean clover (Trifolium subterraneum) seedlings
Effects of the mycorrhizal fungus Glomus intraradices on establishment of subterranean clover (Trifolium subterraneum L.) seedlings in saline conditions were studied in a glasshouse experiment. Growth and nutrient uptake were determined 10, 20 and 30 days after transplanting of mycorrhizal and nonmycorrhizal matched seedlings into soils with five different levels of salinity. Mycorrhizal plants...

Excessive salt accumulation in soil is a major ecological and agronomical problem, especially in arid and semiarid areas. Excessive soil salinity affects the establishment, development and growth of plants, resulting in major losses of production. A pot experiment was set up to examine the effects of arbuscular mycorrhizal fungus (Glomus etunicatum and Glomus versiforme) and salinity on the gro...

This study was conducted to determine the combined effects of salicylic acid (SA) and arbuscular mycorrhizal fungi (AMF) (Glomus mosseae) symbiosis on the growth of pistachio seedlings (Pistacia vera ‘Abareqi’) grown in the greenhouse under different drought stress (DS) levels. The arbuscular mycorrhizal fungi (AMF) colonization or exogenous SA treatment could increase ‘Abareqi’ pistachio seedl...

ABSTRACT-Water stress is the main cause for crop yield reduction in the majority of agricultural regions of the world because it affects almost all plant functions. The effects of Glomus mosseae on growth, nutrients uptake, and antioxidant enzymes of sour orange (Citrus aurantium) and rough lemon) Citrus jambheri) rootstocks were assessed in sterilized soil under greenhouse conditions. A three...
