Artificial Regeneration

Objectives • Reforestation – Restocking or replanting the felled or cleared woodland by artificial means. • Afforestation – Establishment of a forest by artificial means on an area from which vegetation has been absent

Production of Quality seedlings • Preparation of Soil mixture (1: 1) • Sterilization of Growth/Mist chamber with Formalin 10 ml /litre and keep unopened for 24 hours. • Stack the filled Polybags in the chamber. • Collect the cuttings (nodal or leaf cuttings). • Soak in Bavistion for 10 -15 min • Dip in IBA (e. g. , Casuarina – 4000 ppm Eucalyptus – 5000 ppm). • Plant in Polybags inside the chamber. • Same day spray Bavistin or Dithane (1 gm/L) sufficient for 500 bags. • Watering or Misting is done once a day, maintain the temp – 35 -36 0 C and RH – 85 -90 %.

Production of Quality seedlings • 7 th day again spray the fungicides. • And repeat the fungicidal spray on 14 th day as well. • 21 st day spray with cytozyme (1 ml/L) and multiplex growth tonic (2 ml/L) for 1 k bags. • Day 30 th – open the chamber to remove or kill unrooted seedlings • 31 st day move the seedlings to shade house • Maintain the seedlings for another 20 -30 days in shade house and spray growth promoters every 4 th/5 th day. • After 30 days, shift the seedlings to hardening area or field for 30 days.
