1. Differentiation of female flower is also separated into four periods, flower bud differentiation prophase, formation of inflorescences rachises, formation of involucrum, and development of gynoecium.
雌花芽分化分为分化初期、花序轴形成期、总苞形成期和雌蕊发育期4个时期。
2. The distribution of vascular bundle in the rachises of spikelet in different parts of ear had difference, and the number and area of
穗中不同部位小穗的穗轴中的维管束分布有差异；同一小穗中通向各小花的维管束数目和面积也不同。
3. Peduncles, rachises, pedicels, and outside of sepals glabrous.
花序梗，轴，花梗，和除无毛萼片外。
4. Leaf blade elliptic or oblong-elliptic; young branches and inflorescence rachises glabrous; inflorescences shorter than 5 cm; petals absent

5. Peduncles, rachises, pedicels, and outside sepals distinctly hairy.
花序梗，轴，花梗，和在萼片明显有毛外边。
6. Leaf blade usually broadly elliptic or broadly oblong; young branches and inflorescence rachises puberulent; inflorescences to 12 cm; petals present.
叶片通常宽椭圆形或宽长圆形；幼枝和花序轴被微柔毛；花序到12厘米；花瓣宿存 18 R。napalensis 尼泊尔鼠李
7. Branchlets, petioles, rachises, and abaxial leaf surface brownish hirsute, hairs 2-3 mm.
小枝，叶柄，轴，和带褐色多毛的叶背面，头发2-3毫米 22 T。obovatum 毛枝崖爬藤
8. Rachises, bracts, pedicels, and calyces glandular pilose.
轴，苞，花梗和花萼具腺柔毛。
9. As the structure of the pinnaes, palisade and spongy tissues are found in the structure of the rachises of the 9 species of cycads, which is an advent appearance that cycads adapt to the environment.
在9种苏铁类植物叶轴的结构中发现，苏铁科6个种的叶轴都有与羽片一样的栅栏组织和海绵组织结构，这是植物适应环境的一种很进化的现象；
10. At maturity, 14C-reserves in the leaves were exported almost entirely, but in the stems, sheaths and rachises, about 65% 14C-reserves remained, and about 30% - 35% was imported into the kernels.
成熟时叶片的14C几乎都外运了，茎鞘和穗轴中还有大约65%的14C，籽粒中的14C分配率占30%～35%。
11. Observation was made on the growth of the vascular System of wheat rachises in 6 wheat varieties in 1986 and 1987, which resulted in experimental data of number and area of vertical change of the major bundles in the wheat rachises.
1986年与1987年对六个普通小麦品种穗轴维管束系统观察结果，提供了小麦穗轴各部位大维管束数目及其横截面积变化的实验数据。
