Scion Collection: Scions should be collected from the middle to upper parts of the crown of healthy, vigorous mother trees, ensuring that the selected shoots are full, robust, and free from pests. The leaves should be green, glossy, and intact, with a smooth tip surface. Grafting can also be done on selected grafted seedlings or young saplings. The scions must be fully matured, and new shoots should be harvested when they are not actively growing. After cutting, leaves should be removed immediately, leaving the petioles intact. Bundle 50–100 scions together, wrap them in a damp cloth, label them with the species name, and prepare for grafting. If any scions are infested with mites or other pests, wash them in a 1% soap solution or a 500-fold diluted neutral detergent to ensure cleanliness.
Scion Storage: Scions are typically used immediately after collection, but if storage is necessary, maintaining moisture is crucial. Common storage mediums include clean river sand (with 5–10% moisture, easily crumbled when squeezed), or moist and clean moss (such as stone flower). The ideal storage temperature ranges between 4–13°C, with proper humidity levels to maintain high grafting survival rates over several weeks.
Scion Transportation: When transporting, clearly indicate the species, tree number, bundling method, and moisture level. For small quantities, wrap the scions in a wet towel or wet moss and place them in a plastic bag with ventilation holes. For larger quantities, use containers like bamboo poles or wooden boxes lined with moisture-retaining materials such as wet moss. Layer the scions with additional moist material, cover the top with moss, and seal with a plastic film. Ensure consistent moisture and good air circulation during transport. If the journey is long or the temperature is high, first rinse the scions with clean water, then soak them in a sodium hypochlorite solution (or bleach) with an effective chlorine concentration of approximately 0.5% for 5–10 minutes. Rinse thoroughly, pat dry with absorbent paper, and place the scions in a polyethylene bag. Remove as much air as possible, seal the bag tightly, and place another plastic bag over it for extra protection. Insert a layer of moisture-retaining material between the two bags to prevent drying. Avoid direct contact between the scions and the moist materials to prevent rotting due to excessive humidity. To prevent damage from temperature fluctuations, store the packed scions in cardboard boxes and check every 2–3 days. If the petioles were removed, open the bag to remove any excess moisture. If condensation forms due to temperature changes, use absorbent paper to wipe it away before resealing. Even under high temperatures up to 37°C, this method can keep the scions viable for up to 20 days without significantly affecting grafting success.
