A Preliminary Study on Tree Introduction and Domestication of Ceratonia siliqua

This paper reported the ten-year-old results of preliminary study on tree introduction and domestication in Panzihua city,Sichuan province.Both seed germination percent and stocking percent of pretreatment seed were over 80%.Under conventional cultivation,the average tree height,base diameter and crown diameter of a ten-year-old plantation were 5.02 m,10.1 cm,and 49.7 m×8.61 m respectively.The annual growth in crement of tree height could reach 90 cm after 4-5 aplantation,it began first flowering and producing seed after 6-7 a plantation.This species still maintained four important biological features of fire-resistance,arid-tolerance,cold-endurance and easy sprouting.It had a greater value of ultilization in xerothermic river valley area.
