Beneficial soil fungi, known as orchid mycorrhizal fungi, are especially created to support the survival of orchids through an association with the roots of orchids.
The nutrients (nitrogen, phosphorus, carbon compounds, and water) are only available through this specialized association with orchid mycorrhizal fungi. Therefore, and for this reason, the relationship between the orchid mycorrhizal fungi and the orchids is essential for producing the healthiest orchids.
Orchid mycorrhizal fungi supply nutrients to orchids easily and gently, which makes this supply especially important for orchids, as they have fragile root systems, and rely on mycorrhizal fungi to germinate their seeds and establish their initial roots.
Therefore, whether you are using orchid mycorrhizal fungi with orchids grown in nurseries or using these fungal species for commercial floriculture, you will produce stronger, healthier, and more productive orchids, with increased flowering and an environmentally friendly and sustainable way to grow orchids.
Orchid Mycorrhizal Fungi and Mycorrhiza Explained
The relationship between orchids and fungi in the plant kingdom is among the most complex relationships for all types of plants. Due to the nature of this relationship, orchid mycorrhizal fungi are vital for the survival and cultivation of orchids. In comparison to other crops, orchids rely more on their relationship with mycorrhizae for not only nutrient acquisition, but also seed germination, early growth, and continued health of their roots throughout their lives.
Understanding how mycorrhizae function in orchids can provide orchid growers with greater plant strength, improved flowering, and a sustainable method for producing orchids throughout the entire lifecycle of the orchid in nurseries and commercial agriculture operations.
What Are Orchid Mycorrhizal Fungi in Agriculture
Orchid mycorrhizal fungi are specific fungi that have been adapted to colonise orchard roots and provide nutrients to orchards that they cannot obtain efficiently through their own root systems.
Characteristics:
- Allow orchid seeds to germinate in nature
- Act as a source of carbon, nitrogen and mineral nutrients for young plants
- Act as a support structure for root systems and provide nutrients for the orchid plant through the root system
- Act as a protective mechanism against root stress and create an environmental imbalance in the orchid root zone
Importance of Orchid Mycorrhizal Fungi to the Orchards:
Orchids produce dust-like seeds that are so tiny they have no nutrient reserves. As a result, in order for orchids to achieve a successful germination, they require an association with a mycorrhizal fungus. When orchids are inoculated with mycorrhizal fungi for orchid production in agriculture, the fungi provide the plant with greater survival rates; faster establishment times; and healthier root systems.
Orchid Mycorrhiza and Types of Mycorrhiza in Orchids
Orchids form partnerships with a specialized group of mycorrhizae that are distinct from mycorrhizae associated with other common crops. Examples include:
- The orchid mycorrhizae (OrM) type; these are the most specialized fungi associated with orchid roots
- Rhizoctonia-like fungi; these are also commonly found associated with orchids
- Mycorrhizal fungal coils; these structures develop in the interior of orchid root cells
Orchid Roots, Mycorrhiza, and Soil Interaction
Orchid roots differ in structure from other crop root systems. More specifically, they have unique relationships with fungi in the soil. Some common characteristics of orchid root systems and their interaction with mycorrhizae are:
- Thick and spongy root systems that efficiently absorb moisture and nutrients from the environment
- Mycorrhizal infection of the root cells occurs without injuring or harming plant tissues
- Extending beyond the root system, links are formed by fungal networks to reach additional moisture and nutrients.
Orchid Mycorrhizal Fungi in Seed Germination and Growth
Orchids depend on mycorrhizal fungi to provide support throughout its life cycle. Unlike crops, seeds of orchids are exceedingly small and contain no stored nutrients, therefore relying upon mycorrhizal fungi to germinate and grow. In addition to providing support as a seed sprouts and grows, the relationship between fungi and the plants is critical for determining the amount of nutrients absorbed by the plant, the amount of starch and sugars stored and the overall health and vigor of the plant.
Orchid Seed Germination With Mycorrhiza
To be successful, everyone growing orchids from seed to blossom must understand how mycorrhiza works with regard to the different types of orchids. Orchids depend on mycorrhizae to germinate. Because orchid seeds are so tiny, they cannot germinate without mycorrhiza. Mycorrhizal fungi supply nutrients needed to activate the orchids' germination.
How Mycorrhizae Support Orchid Seed Germination:
- Mycorrhizal fungi will penetrate orchid seeds, which initiates growth and development by:
- Giving carbon (energy), nitrogen and minerals
- Stimulating cell division and protocorm formation, and
- Allowing for the successful germination of orchid seeds in both natural and controlled (greenhouse) environments.
Mycorrhiza-Driven Nutrient Uptake in Orchids
Once they germinate, orchids use orchid mycorrhizal fungi to support their growing needs. In most cases, the roots of the plant have more capabilities of securing the plant in place than sucking up nutrients; therefore, the mycorrhiza provide the orchid with essential nutrients.
Through this relationship with the fungi, orchids receive; the key nutrients that orchids require for their growth and development.
The primary nutrients supplied to orchids from the mycorrhiza;
- Nitrogen promotes growth of leaves and shoots
- Phosphorus is primarily concerned with root and flower development
- Micronutrients provide for an integral part of the plant's Metabolism
- Water uptake is increased as a result of enhanced capacity of the root system
Advantageous Aspects of Orchids Grown in Mycorrhiza;
- Greater Root System Development
- Larger and More Vibrant Leaves
- Superior and Longer Lasting Flowers
- Greater Resistance to Environmental Stresses
Through the mycorrhizal relationship, Orchids have developed their own "natural fertilization" process; therefore, improving the orchid's ability to thrive.
Orchid Mycorrhizal Fungi and Seedling Survival
The orchid seedling is very sensitive and fragile. Mycorrhiza greatly increases a seedling's successful establishment. The mycorrhizal fungi Helps to sustain the flower by maintaining nutrient levels and acting as a stabilizer for the young plant.
How Mycorrhiza Can Benefit the Establishment of the Orchids:
- Increased Resistance to Drought and Transplant Stress
- Improved Availability of Roots in the Potting Material
- Reduced Pathogenic Microbial Threats to Seedlings
- Supports Gradual, Balanced Growth of the Orchids
Mutual Benefits of Orchid Mycorrhizal Fungi and Mycorrhiza
In addition to providing nutrients to orchids through the symbiotic relationship between orchids and mycorrhizal fungi, it is important to note that orchids will derive more benefits from this partnership than they will from using traditional fertilizers. Mycorrhizae are critical for the germination of orchid seeds, the development of seedlings, and the ability of the plant to survive in nutrient-deficient soils. The understanding and promotion of this mutualistic relationship will lead to improved establishment of plants, better consistency of flowering, and superior quality of crops.
Nutrient Exchange in Orchid Mycorrhizal Fungi
The role of orchid mycorrhizal fungi in supplying essential nutrients to orchids is critical since these fungi allow for improved absorption of certain nutrients by the orchid compared to the plant's root system alone.
Some Examples of Nutrients Supplied by Orchid Mycorrhizal Fungi:
- Nitrogen (for leaf and shoot development)
- Phosphorus (for the development of roots and flowers)
- Carbon (for the germination and early growth stages of orchids
- Water and Micro-nutrients (for optimal health of the orchid)
The Benefits That Orchids Provide the Orchid Mycorrhizal Fungi:
- Sugars that are formed during photosynthesis.
- A safe, stable root habitat for the fungus.
Mycorrhiza Supporting Orchid Adaptation
Mycorrhiza allows orchids to adapt in adverse conditions such as low-nutrient growing media, fluctuating moisture levels, and environmental stressors.
Mycorrhiza Enhances Orchid Adaptation By:
- Increasing tolerance of orchids to nutrient-depleted growing media
- Increasing root establishment of orchids in bark, moss, and other inert growing media
