四川省华夏农业科技开发中心高级农艺师石卓才，7O年代初期从台湾晚白油中发现一矮化芽变抽株。经过20多年的选育，现已培育出一个植株奇矮、晚至春节成熟的抽树新品系——矮晚抽。现在该品系的原始母树已有25年树龄，其株高、冠径都未超过l，5米。繁育后代已达数万株，最早的 Shih Tzu-cai, a senior agronomist at Huaxia Agricultural Science and Technology Development Center in Sichuan Province, discovered a dwarfing mutant strain from early late white oil in Taiwan in the early 1970s. After more than 20 years of breeding, we have cultivated a new plant with low plant growth rate and mature maturity from late spring to late spring. Now the line of the original tree has 25 years old, its height, crown diameter no more than l, 5 meters. Breeding generations have reached tens of thousands of strains, the earliest
