一个比较先进的木麻黄无性繁殖法已被研究出来。利用1年生植株或3个月生萌芽条的小枝,经过生长激素的处理。放入烧杯清水中,置于直射光照下培养,最快6天开始出根,15天出根率达80％以上。我们还研究出了一个木麻黄抗青枯病品系的快速测定法,筛选出几个速生抗病的品系,并已在林区进行扩大试验。此外,我们对病原菌的生理小种和菌系,以及木麻黄的抗病机理也进行了初步的研究。 A more advanced method of cloning Casuarina has been developed. Use of 1-year-old plants or 3 months sprouting branches, after growth hormone treatment. Into a beaker of water, placed in direct sunlight training, the root out of the fastest six days, 15 days the root rate of more than 80%. We have also developed a rapid assay for the resistant strain of Casuarina equisetifolia and selected several fast-growing and disease-resistant strains that have been scaled up in the forest. In addition, we conducted a preliminary study on the physiological races and bacterial strains of pathogenic bacteria and the disease resistance mechanism of Casuarina equisetiva.
