红麻是以收获韧皮纤维为目的,因而它的纤维含量和纤维重是育种的重要目标之一。但在测定某一新品种的纤维含量和纤维重时,工作比较繁琐。为此,我们拟探索一种简便、有效的测定单株纤维重的方法,应用于单株考种,以加快育种工作。 (一)红麻单株主要经济性状与单株纤维重的关系红麻植株的高度,茎的粗细,麻皮的厚薄,是组成红麻单株纤维重量的重要因素,为了明确红麻单株的选择标准和选择效果,研究红麻单株主要农艺性状与单株纤维重的相互关系是十分必要的。据我们对红麻7个品种的株高、茎粗、皮厚与单株纤维产量的测定,结果表明,单株的株高、茎粗、皮厚与单株的纤维产量成显著的正相关。这说明红麻株高、茎
Kenaf is harvested for the purpose of bast fiber, so its fiber content and fiber weight is one of the important goals of breeding. However, the determination of a new variety of fiber content and fiber weight, work is more complicated. To this end, we intend to explore a simple and effective method of determining the weight of a single plant fiber, applied to test plant species to speed up breeding work. (A) the main economic characteristics of kenaf single plant fiber weight relationship The height of kenaf plant, stem thickness, thickness of kiwifruit kenaf is an important factor in the weight of kenaf fiber, in order to clear kenaf plant The selection criteria and the selection effect, it is necessary to study the relationship between the main agronomic characters of kenaf and single fiber weight. According to our determination of plant height, stem diameter, skin thickness and yield per plant of seven cultivars of kenaf, the results showed that there was a significant positive correlation between plant height, stem diameter and thickness and plant fiber yield . This shows kenaf height, stem
