Frequently Asked Questions

What is Plant Tissue Culture?

It is the process of producing plants from tissues of the desired plant in an artificial nutrient medium under controlled environment. The plants so produced would be exactly similar to the mother plant in all aspects.

Why one should go for tissue culture plants?

Tissue culture plants are qualitatively better as they are produced under aseptic conditions and controlled environments. One should go for tissue culture plants for the following reasons:

  • Tissue culture plants are vigorous and grow faster than conventional plants.
  • High degree of uniformity compared to conventionally propagated plants.
  • Tissue culture plantlets are free from diseases and pathogens.
  • It is possible to multiply plants that are difficult to propagate by traditional methods.
  • Tissue culture plants yield better as they are produced under optimal conditions from selected mother plants.

What is an explant? What are the types of explants used in Plant Tissue Culture?

An explant is the part of a plant which has the regeneration potential and can give rise to the whole plant. Various types of explants used in plant tissue culture include:

  • Nodal segments
  • Apical meristems
  • Roots
  • Cotyledons
  • Embryo
  • Leaf disc, leaf blade, petiole
  • Pedicle
  • Anther, ovary

Are tissue culture plants more prone to pests and diseases than conventionally propagated plants?

No, tissue culture plants are free from diseases and pests if standard procedures are followed during production. While tissue culture plants grow faster and better, they are as vulnerable to pests and diseases as any other plant unless proper precautions are taken. However, tissue culture plants are free from soil-borne diseases.

Do tissue culture plants yield better than conventional plants?

Yes, tissue culture plants tend to yield better. As they are uniform, vigorous, and disease-free, following proper cultivation practices can lead to higher yields compared to conventional plants.

What are the economic advantages of date palm tissue culture?

The economic advantages of date palm tissue culture are significant. Tissue culture ensures true-to-type genetics, as propagation via seeds can result in genetic variation, especially for dioecious varieties. Additionally:

  • Faster growth cycle compared to traditional seed and offshoot propagation.
  • Higher production efficiency, enabling larger-scale and more profitable farms.
  • Increased demand for high-quality dates can be met using tissue culture techniques.

As the demand for high-quality dates increases, tissue culture is becoming an essential technique to meet this need.

What is the Specialty of Dates?

Dates are sweet fruits that come in many varieties, including fresh, wet, semi-dry, and dry. The antioxidants, vitamins, and minerals in dates contribute to brain, digestive, and heart health, and they are also believed to help ease natural labor.

What are the special features of date palm?

The date palm grows to about 23 meters (75 feet) tall, with a crown of graceful pinnate leaves that are about 5 meters (16 feet) long. Its floral spikes emerge from the axils of the previous year's leaves. This majestic tree is essential for date production in arid climates.

Which soil is suitable for dates?

Dates grow best in soils with a pH range of 8 to 11. Sandy loamy soils with good moisture retention, aeration, and proper drainage are ideal. Soils containing calcium carbonate should be avoided for date farming.

Why is artificial pollination recommended for date palms?

Although date palms are naturally pollinated by the wind, artificial pollination is necessary for commercial production. It ensures better fruit set and higher yields, particularly in regions where natural pollination may be insufficient.
