The Tissue Cultured Plants are the resultant clones that are true-to-type copies of the selected Elite mother plants produced through a collection of techniques used to maintain or grow plants or parts of plants, placed on artificial growing media.

In the process, aseptic and healthy plant cultures are Initiated, tested for diseases and healthy plants are selected for multiplication, shooting, and rooting. All the processes are ensured under aseptic and controlled microclimatic conditions called Micropropagation. Hardening is conducted under greenhouses and in shade houses.

The sterile environment in the laboratory makes it possible to keep plants completely free of diseases, which is a large advantage overgrowing in the field or in greenhouses.

We provide the healthy (Virus-Free) high yielding Banana verities, True to type and healthy ornamental plants, and virus free potato Mini-tubers which have many advantages over the conventionally grown plants in their yield, early maturity, less use of pesticides, and especially the quality of its end products (Fruits, Vegetables and Flowers). 

Our Quality Disease-Free Tissue Cultured Products:

  1. Banana Tissue Cultured Plants (Virus-Free)
  2. Other Plants
      • Gerbera Double Hybrid
      • Potato Minitubers seeds (Virus-Free)


NOTE: Grow your own desired plant variety on demand through Tissue Culture.

Identify The Specie of Your Plant Sample:

When it is difficult for you to identify the species of your plant sample through conventional methods, we can identify for you through DNA barcoding- a method of species identification using a short section of DNA from a specific gene or genes. The principle of DNA barcoding is that, by comparison with a reference library of such DNA sections (sequences), an individual sequence can be used to uniquely identify an organism to species, in the same way, that a supermarket scanner identifies an item in its stock against its reference database.

Currently, we offer plant species identification via DNA Barcoding.

Stability studies of a product are the study of the capability of a particular formulation, in a specific container /Closure system to remain within its physical, Chemical, and Microbiological specifications throughout its predetermined shelf life under specified storage conditions. Normally it is done to establish shelf life or expiry date for the products.

Physical, Chemical & Microbiological parameters are tested as per customer requirements at each specified study.
We shall design plans & Protocols for Stability Studies according to the Current Regulatory Requirements for your products as per ICH guidelines & ASEAN.
Normally two types of stability studies are being carried out as below;


Sr. #



Storage condition

Testing frequency


Accelerated Conditions

6 Months

Temperature = 40 ± 2oC
Humidity = 75 ± 5%

To, T3, T6


Long Term Study
(Room Conditions)

As per shelf Life

Temperature = 30 ± 2oC
Humidity = 75 ± 5 %.

First Year( Initial) Testing
To, T3, T6, T9, T12,

Every six months T18, T24

Third Year
Annually T36

However, storage conditions and testing frequency can be changed as per customer requirements,

Qarshi Research International is working to launch various training courses focusing on the technical fields of testing and calibration.

We are also working to be the first accredited organization in Pakistan that will provide Certified Reference Material (CRM) in various food matrices.

To cater the need of our valued export-oriented customer under one window operation, we will also provide accredited inspection services in addition to accredited testing.
