The basic structure of the inflorescence is the cyme (branchlets arising from the bracteole axils, the bracteoles serving as bracts for upper flowers), which can be reduced to one flower with two bracteoles and a bract. Units of dispersal vary considerably (capsules opening with lower part persistent, flower and bracteoles falling together, or cymose partial inflorescences breaking off above bract) and can be characteristic for genera. Several genera possess long trichomes serving dispersal at the base of the tepals.
花序的基本的结构是聚伞花序小枝起因于bracteole腋，散布的单位变化多样(蒴果开裂下半部分的宿存，花和小苞叶一起脱落，或部分聚伞花序在苞片以上裂开并且可以作为属的特征一些属在花被片的基部有长的毛状体用于散布Digera arvensis Forssk吗？

The results are as follows:(1) The morphological investigation indicated that the nectaries werelacked on the main nervation, calyx and bract of cotton line 97014 comparedwith TM-1. Alveolate hollow was absent at main nervation of the mature leaf.Results of cytological analysis showed that 97014 lacked nectariferous structure.Where nectary inserted were parenchyma cells, cupped structure and brownnectariferous substance on the lower epidermis were not found.
主要研究结果如下：(1)以棉花无蜜腺品种97014与有蜜腺棉花遗传标准系TM-1为材料，进行形态学比较研究，结果表明棉花无蜜腺品种97014叶片中脉、花萼和苞叶上都缺少蜜腺，成熟叶片叶脉、花萼和苞叶上均无蜂窝状凹陷；组织与细胞切片观察发现，97014缺少蜜腺组织结构，在蜜腺着生处为排列整齐的薄壁细胞，且在下表皮看不到凹陷的组织结构和褐色的蜜腺分泌物。

The results showed that the initiation of leaf and bracteal primordia took the S shape, and that of spikelet and floret took the rise stage of parabolic shape in relation to GDD (growing degree days after sowing) in wheat.
结果表明，小麦叶原基和苞叶原基分化与播后累积生长度日(GDD ，growingdegreedaysaftersowing)的关系呈S形曲线，而小穗原基和小花原基为上升段抛物曲线。

Significant differences in cytosine methylation level among the three tissues and the same changing tendency in two inbred lines were detected. Both MSAP (methylation sensitive amplification polymorphism) ratio and full methylation level were the highest in bracteal leaf, and the lowest in tassel.
结果表明，3个组织甲基化水平存在一定差异，并在两自交系中表现出相同的变化趋势，即雌穗苞叶的甲基化敏感扩增多态性比率和全甲基化率最高，穗位叶次之，雄穗最低。

RT-PCR analysis showed that GhMADS1 gene expressed in petals, stamens, ovules and fibers, but not in roots, stems, leaves, bracts and sepals. The strongest expression of GhMADS1 gene was detected in petals. But in floral buds of a cotton homeotic mutant (CHV1), whose floral organs are all converted to bract leaf-like organs, the transcript of GhMADS1 gene was not detected.
RT-PCR分析显示，该基因在陆地棉的花瓣、雄蕊、胚珠和纤维中表达，特别是在花瓣中表达量最高，而在根、茎、叶等营养器官和棉花同源异型突变体CHV1（所有花器官均变为苞叶状叶性器官）的变异花蕾中不表达。

The highest total flavonoid rate was 1.127%. An all-round evaluation for the antioxidant activity of the flavonoids extract from zizania-bract was carried out with that of ascorbic acid as the control. The evaluation indexes included the cleanup rate of the polyphenolic extract towards superoxidized anionic radicals, hydroxyl radicals, DPPH free radicals, the deoxidizing ability, and the antioxidant activity towards the peroxidize of lipids and edible oils.
采用抗坏血酸作为对照，全面测定了茭白苞叶总黄酮对超氧阴离子自由基、羟基自由基、DPPH自由基的清除率，以及还原能力、抗脂质过氧化活性和对食用油脂的抗氧化性的影响，结果表明，白苞叶中的总黄酮是一种有开发价值的天然抗氧化剂。
