With American botanist cypress apply reach Halier, the really beautiful doctrine that British botanist breaths out Qin Song to be a delegate thinks the flower of angiosperm is come by evolution of ball of leaf of primitive gymnospermous bisexual spore, consequently tentative idea angiosperm is the Benneisu that in coming from gymnosperm, eradicates already iron eye, draft Su Tie especially , the bud on ball of its spore leaf piece evolve for perianth, sporule leaf evolves for stamen, big spore leaf evolves for pistil , axis of ball of its spore leaf shortens for rachis.

以美国植物学家柏施及哈利尔，英国植物学家哈钦松为代表的真花学说认为被子植物的花是由原始裸子植物两性孢子叶球演化而来，因而设想被子植物是来自裸子植物中早已灭绝的本内苏铁目，非凡是拟苏铁，其孢子叶球上的苞片演变为花被，小孢子叶演变为雄蕊，大孢子叶演变为雌蕊，其孢子叶球轴则缩短为花轴。

Plant monoecious. Male flowers sometimes solitary, sometimes in a thyrse 5-7 cm, 2-3 cm in diam.; pedicels 0.8-1.5 cm; sepals 2 large, 2 small; petals orange, obovate, 1-5 × as long as sepals; stamen fascicles stalk 2-3 mm, each fascicle with 50 anthers; anthers aggregated into a head, 2-celled, cells longitudinally dehiscent; pistillode columnar; stigma distinctly peltate, 4-lobed.

These male sterile transgenic plants with TA29 Barnase gene have the same horticultural characters which can be also inherited steadily by plants in next generation as non transgenic ones. But their flowers bear fully catagenetic stamen lacking pollens, normal fragrant nectaries and strong pistils able to receive pollens from other plants or different cultivars and set seeds. At the meantime, the sterility i...

带有TA 2 9 Barnase基因的雄性不育植株的园艺学性状与未转化植株相同，并且其性状在后代中稳定不变；不育植株的花朵表现雄蕊完全退化，但蜜腺和雌蕊健全，能接受外来花粉，杂交结实率较高；同时，雄性不育植株的不育性在后代中出现分离，不育株率占 12 。5%～ 85.7%；此外，不育性状具有镶嵌性

Pollen-tube growth down the style is both positively and negatively chemotropic; the tube grows toward chemicals secreted by the pistil, and away from atmospheric oxygen.

花粉管沿着花柱的生长是既有正向性也有负向性的：花粉管向着由雌蕊分泌的化学物质生长，同时远离空气中的氧气生长。

Stamens inserted at lower third of corolla tube; anthers sagittate, connivent, adherent to pistil head, anther tips included or exserted, cells spurred at base; disc scales 5, free.

Flowers bisexual; stamens 2 × as many as petals or rarely fewer; gynoecium 2-5-loculed; ovules 1 or 2 per locule; fruit either without pulp vesicles or with sessile pulp vesicles; leaves odd-pinnately 3- to many foliolate, digitately 3-foliolate, 1-foliol

花两性 雄蕊2 *更少的花瓣或很少的同数；雌蕊群2-5室；胚珠每室1或2；果或者没有果肉囊或具无梗果肉囊；奇数羽状复叶的叶3-对具小叶的很多，掌状具3小叶，1－foliol 16

Leaves odd-pinnately 3- to many foliolate or sometimes digitately 3-foliolate (occasional leaves even-pinnate, 2-foliolate, or 1-foliolate); functional gynoecium 1-5-loculed, with distinct carpels or carpels basally connate; fruit of 1-5 distinct or basal

叶奇数羽状复叶3-对具小叶的很多或有时具3小叶偶然偶数羽状复叶，2具小叶，或单身复叶；功能的雌蕊群1-5室，具离生的心皮或心皮基部合生； 1-5离生或者基部的果 1 Zanthoxylum 花椒属

To detect such correlations, which may provide insight to understand flower evolution, 40 Pedicularis species representing all corolla types of the genus were studied.

研究表明，在马先蒿属植物的种间存在明显的花粉大小数量间的权衡关系，花粉大小与雌蕊长度成显著的正相关关系。

The concept of equivalent rotationally rigidity is offered and the formula of rotationally rigidity is obtained.

主要做了如下几个方面的工作：对伸臂位于顶部的单层框架—筒体模型进行分析，提出了等效转动约束的概念和转动约束刚度的表达式。
