Grafted Plant Research at Sansar Green

Advancing Grafting Technology, Rootstock Research & Quality Planting Material Development

Stronger Roots. Healthier Plants. Advanced Horticulture. Sustainable Agriculture.

Introduction

Sansar Green is committed to advancing grafted plant research, innovative horticultural propagation techniques and scientific nursery technologies to support quality planting material development, commercial horticulture and sustainable agricultural production.

Through the research and innovation initiatives of Sansar Green Mission Private Limited, a DPIIT-recognised agritech startup established in 2020, we aim to explore advanced grafting methods, rootstock–scion compatibility, plant establishment, nursery management and propagation technologies suitable for diverse Indian agricultural conditions.

Grafting is a specialised horticultural technique in which a shoot portion, known as the scion, is joined with a compatible rooted plant, known as the rootstock. When successfully united, the two components grow together as one plant.

Appropriate grafting combinations can help horticultural producers benefit from selected rootstock characteristics, including growth regulation, adaptation to certain soil conditions and resistance or tolerance to specific pests and diseases.

At Sansar Green, grafted plant research forms an important part of our broader plant biotechnology, horticultural innovation and nursery development vision.

Our objective is to connect scientific research with practical propagation technologies that support farmers, commercial nurseries, horticultural entrepreneurs, agricultural institutions and plantation initiatives.

Guided by our philosophy of “मिट्टी से मंडी तक” — Soil to Market, we seek to transform horticultural research into practical opportunities for agricultural productivity, quality planting materials and sustainable rural entrepreneurship.

Our Vision

To develop advanced grafted plant research and propagation capabilities that contribute to quality planting material production, improved horticultural practices and sustainable agricultural development.

We envision a future where scientifically evaluated grafting technologies support reliable plant establishment, productive horticultural systems and commercially viable nursery enterprises.

Our Mission

Our mission is to promote applied research in grafting, rootstock technologies, nursery management and horticultural propagation.

Our objectives include:

Advancing research on grafting methods and plant propagation.
Evaluating rootstock–scion compatibility.
Exploring rootstock characteristics for selected horticultural crops.
Improving understanding of graft union formation and plant establishment.
Investigating grafted plant growth, vigour and root development.
Studying nursery conditions affecting grafting success.
Supporting the development of healthy and uniform grafted planting materials.
Exploring grafting applications in fruit crops and selected vegetables.
Conducting nursery and field-level propagation evaluations.
Encouraging horticultural research collaboration and technology transfer.

Understanding Grafted Plants

A grafted plant is developed by joining two compatible plant parts.

Rootstock: The lower portion that provides the root system and may influence plant vigour, nutrient and water uptake, and tolerance to particular soil-related challenges.

Scion: The upper portion selected for desirable characteristics such as fruit quality, growth habit or other cultivar-specific traits.

Successful grafting requires biological compatibility, appropriate alignment of cambial tissues, suitable environmental conditions and careful management during graft union development.

Why Grafted Plants Matter

When suitable rootstock–scion combinations are used, grafting can offer important horticultural advantages:

Propagation of selected cultivars.
Maintenance of desirable scion characteristics.
Improved adaptation to certain soil conditions.
Management of specific soilborne disease challenges.
Regulation of plant vigour.
Support for productive orchard systems.
Improved uniformity of planting materials.
Potential improvement in plant establishment.
Opportunities for specialised nursery enterprises.
Support for modern commercial horticulture.

These benefits depend on the plant species, rootstock, scion, growing conditions and management practices. Grafting does not automatically guarantee higher yield or disease resistance.
