Why use rootstock when growing kiwis?

A rootstock does more than just support the plant: it plays a key role in the productivity, health, and adaptability of orchards. Its main functions include:

• Nutrition and Nutrient Absorption: A robust root system optimizes access to water and essential elements.
• Environmental adaptability: It allows the plant to adapt to specific climatic and soil conditions.
• Increased resistance: Some rootstocks, such as Bounty 71, provide natural protection against diseases and pests.
• Vigor management: A suitable rootstock makes orchard maintenance and harvesting easier.
• Yield Optimization: Improved vigor and efficient absorption result in higher quality and greater quantity of fruit.

Faced with the challenges of heavy soils, diseases such as Psa, or growing market needs, the Bounty 71 offers solutions adapted to the expectations of modern kiwi growers.

Bounty 71: Origin and exceptional characteristics

Developed from a seedling of Actinidia macrosperma, Bounty 71 was developed in New Zealand, a world leader in kiwifruit cultivation. With over 15 years of successful use, this rootstock has proven its effectiveness and robustness.

Taproot system: A decisive asset

Unlike other rootstocks, Bounty 71 has a tap root system that:

• Penetrates deep into the soil to access water and nutrients, even in difficult conditions.
• Reduces the risk of waterlogging, a common problem in heavy soils.
• Promotes increased resilience to water pressures.

Adaptation to heavy and poorly drained soils

Heavy or poorly drained soils can hinder plant growth. The Bounty 71 is perfectly suited to these soils thanks to:

• Better water management: Reducing risks associated with excessive humidity.
• Steady growth: Even in adverse conditions, plants remain vigorous and productive.

These characteristics make it a preferred choice for French regions where soil conditions can be demanding.

Psa Resistance: Essential Protection

Psa bacterial blight (Pseudomonas syringae pv. actinidiae) is a major threat to kiwifruit orchards. Bounty 71 offers commercial tolerance to Psa, allowing for:

• Reduce losses related to this disease.
• Protect the long-term health of plants.

Optimized yield and quality fruits

With the Bounty 71, kiwi farmers can benefit from:

• Increased yields: Abundant flowering and regular production.
• Large fruits: Better dry matter and superior taste quality.
• Commercial adaptability: The fruits produced meet the requirements of national and international markets.

A flexible solution for diverse needs

The Bounty 71 is available in several formats:

• In peat or coconut fiber pots: An ecological and practical option.
• With or without grafting: To adapt to your specific needs.
• Double planting systems: An ideal solution for optimizing the surface area of ​​your orchards.

These different options allow kiwi growers to integrate the Bounty 71 into varied and efficient production systems.

Recommended grafting techniques

The success of the rootstock also depends on the grafting and pruning techniques used. For Bounty 71, here are the recommended periods:

• Spring (March-April): Cleft or inlay grafts.
• Summer (mid-July to early September): “Dormant eye” bud grafts.

These techniques guarantee optimal recovery and harmonious growth of the plants.

Comparison with other rootstocks

Although rootstocks like Roki are gaining popularity, Bounty 71 stands out for:

• 15 years of field experience: Proven reliability.
• Heavy Soil Adaptation: Exceptional performance in difficult conditions.
• Resistance to Psa: An essential asset for protecting orchards.

The strategic role of rootstock in kiwi cultivation

A rootstock, the lower part of a grafted plant, plays much more than just a supporting role. As the true foundation of the plant, it determines its growth, vigor, and production. Here are its main contributions:

• Optimal plant nutrition: Thanks to its root system, it ensures efficient absorption of water and nutrients.
• Adaptability to soils and climates: Some rootstocks adapt better to specific soils (heavy, light, calcareous) or are more resistant to environmental stresses.
• Disease protection: A good rootstock improves the plant's resilience to soil-borne pests and diseases.
• Vigor and Yield Management: It facilitates growth regulation and helps maximize production while simplifying orchard management.

The rootstock is therefore an essential lever for efficient and sustainable kiwi cultivation.

Why is Roki rootstock revolutionizing kiwi growing?

Roki rootstock has been specifically designed to meet the current challenges of kiwifruit cultivation in France. Its adaptability, resistance, and vigor make it a strategic choice for growers seeking modern solutions.

Exceptional adaptability

The Roki adapts to a wide variety of soil types, including:

• Heavy and clayey soils: Thanks to its taproot system, it overcomes the compaction problems often encountered in these terrains.
• Soils affected by kiwi dieback: A common problem in France. The Roki tree is particularly resilient in the face of these complex conditions.
• Chalky or heterogeneous soils: Unlike other rootstocks, Roki excels in varied terrains, thus broadening its scope of application.

Increased resistance to water stress

Water management is a critical factor in kiwifruit cultivation. The Roki is distinguished by:

• Better absorption: Its pivoting system efficiently captures water and nutrients, even in dry conditions.
