• Application of 6-Benzylaminopurine (6-BAP) in Promoting Seed Germination and Seedling Survival Across Various Plants

• Application of 6-Benzylaminopurine to the promotion of photosynthesis and yield enhancement in various plant species

• Application of 6-Benzylaminopurine (6-BA) in Regulating Flower-Fruit Development and Promoting Fruit Setting & Enlargement Across Plant Species

6-Benzylaminopurine (6-BA) not only promotes seed germination, enhances photosynthesis, and regulates flower-fruit development, but also delays senescence and improves postharvest preservation. Below are the application methods for different plant species.

1. Cabbage & Water Spinach

   • Method: Spray leaves or dip in 30 mg/L 6-BA after harvest.

   • Effect: Extends storage period.

2. Rapeseed & Cauliflower

   • Method: Apply 10–15 mg/L 6-BA via foliar spray or dipping at harvest.

   • Effect:

     • Reduces postharvest yellowing and sensory quality decline.

     • Suppresses respiration rate, chlorophyll degradation, and malondialdehyde (MDA) accumulation.

     • Maintains high total phenolic content and DPPH radical scavenging capacity.

3. Sweet Pepper

   • Method: Foliar spray with 10–20 mg/L 6-BA pre-harvest or postharvest dipping.

   • Effect: Inhibits respiration during storage and delays the respiratory peak.

4. Radish & Lettuce

   • Method: Apply 5–10 mg/L 6-BA via foliar spray at harvest or postharvest dipping.

   • Effect: Delays respiratory peak and prolongs shelf life.

5. Melons

   • Method: Postharvest immersion in 10–30 mg/L 6-BA for 5 minutes.

   • Effect: Enhances storage tolerance.

6. Jujube

   • Method: Pre-harvest spray with 15 mg/L 6-BA.

   • Effect:

     • Inhibits declines in peroxidase (POD) and catalase (CAT) activities.

     • Reduces malondialdehyde (MDA) accumulation and flesh tissue electrolyte leakage.

     • Delays fruit ripening and senescence.

7. Grape

   • Method: Spray leaves 3–4 times with 20 mg/L 6-BA during mid-late growth stages.

   • Effect: Increases leaf chlorophyll content and delays leaf senescence by ~15 days.

8. Chinese Toon

   • Method: Postharvest 100 mg/L 6-BA dip for 10 seconds before refrigeration.

   • Effect: Slows chlorophyll degradation and extends storage duration.

9. Honey Peach

   • Method: Spray fruits with 500 mg/L 6-BA.

   • Effect:

     • Enhances resistance to brown rot by maintaining cell membrane integrity and delaying senescence.

     • Significantly reduces brown rot incidence.

10. Lychee

    • Method: Postharvest dip in 100 mg/L 6-BA for 1–3 minutes.

    • Effect: Prolongs storage life.

11. Cut Flowers (Lily, Rose, Peony, Chrysanthemum, Carnation)

    • Method:

      • Spray 25–50 mg/L 6-BA during mid-late growth stages.

      • Dip cut flowers in 1.5–2.5 mg/L 6-BA solution.

    • Effect: Extends vase life and delays senescence.
