VAM Full Form

Introduction

VAM is a particular type of mycorrhiza in which the fungus infiltrates the vital root cells of a certain plant. Mycorrhiza is a type of mutualistic association between fungi known as mycelia and the roots of plants. In this article, we will have an elaborated and descriptive acknowledgement of VAM. Through this article, the students will be able to understand the concept and idea of VAM.

Full form of VAM

Vam is an endotrophic (live inside) mycorrhiza formed by aseptate phycomycetous fungi. VAM is an abbreviation which refers to Vesicular arbuscular mycorrhizae is believed that both the initial colonisation of the earth by plants and the evolution of plants were greatly aided by the formation of the arbuscular mycorrhizal symbiosis.VAM is the most common type of endomycorrhizal fungi. It tends to form a hyphal,tree-structure known as an arbuscular which acts as the main site for the process of exchange.

Effect of VAM on Cucurbits

1. The presence of VAM can tend to have a cause on male flowers in order to produce more pollen and therefore spread their genes all around.

2. The number of healthier seeds by female flowers increases.

3. The amount of nitrogen and phosphorus which tends to help in the reproductive success of cucurbits can be increased through the help of VAM.

4. VAM provides nutrients like phosphorus in large numbers for the purpose of greater growth keeping it distant from cracking.

What is Glomus?

• Glomus is known as the most common gene present in VAM with a number of 90 identified species.

• A high number of species of this group provide globose or irregular spores having a thick outer membrane which helps them to host the plants for colonisation.

• The pores present here often have pigmentation which is usually yellow in colour.

Importance of VAM

1. VAM provides a number of plants with a normal root surface area.

2. VAM makes the nutrients and water reach the plant properly.

3. VAM enables the water-stable soil particles to improve the soil density and soil quality.

4. VAM causes tolerance and resistance in plants.

5. VAM raises the intake of nutrients through plants.

Characteristics of VAM

Microorganisms have played a crucial part in assisting the production of crops by adopting improvements in the soil's characteristics and plant nutrition. The Vesicular-Arbuscular Mycorrhiza (VAM), a type of fungus that greatly contributes to the dynamics and enhancement of soil nutrients and improves the physical, chemical, and biological aspects of soil, is one of these microorganisms. Due to a decline in phosphorus solubility, mobility, and fixation in the soil, it is now difficult for plants to acquire the mineral. However, the mycorrhizal symbiotic relationship between fungi and plants makes it simple for plants to increase their phosphorus intake. As a component of its host plants, vesicular-arbuscular mycorrhiza (VAM) is particularly powerful in changing how soil phosphorus is mobilised.

Vesicular-arbuscular mycorrhiza (VAM) is known to assist plants by giving them adequate vigour so that they may withstand ailments, pathogens, and adverse weather conditions in addition to increasing the availability of phosphorus. VAM should be encouraged on the roots, either with the use of nursery grow bags or by blending it in with compost, as it is thought to be active close to the area of the plant's roots.
