海南石梓,学名Gmelina hainanensis。据《海南主要经济树木》载称:其木材巨观构造和力学性质与世界名材柚木相近,当地誉为一等名材。生长迅速,人工栽培条件下5年生胸径即达14厘米,树高7米,为海南热带一类用材树种。由于反复砍伐利用、多代萌芽更新,因而生长逐渐衰退,干形多弯曲,因此进行人工选种,并通过嫁接繁殖来保持和提高其优良的遗传品质,是我们嫁接试验的主要目的。试验工作在海南尖峰岭地区进行。 Hainan Shi Zi, scientific name Gmelina hainanensis. According to “Hainan’s major economic trees,” contains: its timber giant structure and mechanical properties similar to the world name teak, the local reputation as first-class name. Rapid growth, artificial cultivation of 5-year-old diameter of up to 14 cm, tree height of 7 meters, Hainan tropical one timber species. Due to repeated deforestation, many generations of sprout renewal, so the growth of recession, dry and more bending, so artificial selection, and through grafting to maintain and improve their excellent genetic quality is the main purpose of our grafting test. Experimental work in Jianfengling area of ​​Hainan.
