- The capacity of dehiscent anther was determined to the size and the morpha of anther stomium cell, epidermal cell and fibrous stratum's plastic property of the pollen sac wall. 成熟花药开裂的能力与花药裂口细胞的大小、形态有关,同时又与成熟花粉囊壁的表皮细胞和纤维层细胞的可塑性结构功能有关。
- In TRP, the pollen was chubbier, pollen sac more spatial, stigma plate bigger, stigma more secretion, both filament and style and their epidermis cells longer than DRP. 花药形态结构更为丰满,药室空间较大,柱头面积增大且分泌的粘液较多,花丝和花柱以及它们的表皮细胞均较长。
- Inflorescence an axillary heads; flowers bisexual, petals5, white, ribbon-like,1.5 cm long; stamens5, filaments very short, anthers ovoid, with2 pollen sac opening each by2 vertical valves, connectives exserted; staminodes5, bifid. 头状花序腋生,花两性,花瓣5,白色,带状,长1.;5厘米;雄蕊5,花丝极短,花药卵形,具2个各2瓣裂的花粉囊,药隔突出;退化雄蕊5,叉状分裂。
- Histology of Lilium anther. Tapetum lining the pollen sacs. 百合花药结构,绒毡层衬在花粉囊内。
- Pollen cones with 8-12 microsporophylls, each with 3-6 pollen sacs. 雄球花具8-12小孢子叶,其中每个花粉囊。
- Pollen cones with (6-)10-12 microsporophylls each with 3 pollen sacs. 雄球花具(6-)10-12小孢子叶其中每个花粉囊。
- Each lobe contains two pollen sacs that produce very large quantities of small pollen grains. 左右两侧花粉囊之间是薄壁细胞构成的药隔,药隔中的维管束与花丝维管束相连。
- Pollen The MICROSPORES of seed plants, produced in large numbers in the pollen sacs, or stamens. 花粉:指种子植物的小孢子。
- Pollen cones pedicellate, globose, with overlapping bracts at base;microsporophylls 6-14, shield-shaped, each with 4-9 radially arranged pollen sacs. 雄球花圆球形,基部覆瓦状排列的苞片,雄蕊6-14枚,盾状,花药4-9丝,辐射状排列;
- Hand-pollination also showed that pollen grains of anaflexistylous flowers have matured before the dehiscence of pollen sacs. 研究结果表明即使不考虑花柱运动, 山姜属植物也具有异型雌雄异熟的特性。
- The results showed that the anther of Niitaka and Atago was smaller and had few pollen grains, thus resulting in the formation of sterile empty pollen sacs. 结果表明,新高、爱宕花药较小,花药内花粉粒数量很少、且活力低,表现出雄性不育的空囊花药。
- There is a high pollen count in the air. 空气中有很高的花粉计数。
- An organic sac or pouch, such as the udder of a cow. (牛的)乳房有机体器官的液囊或袋,如牛的乳房
- broken pollen sacs in vicinity of stigma 柱头附近破碎的花粉囊
- The peritoneal cavity is a closed sac. 腹膜腔是一个封闭的囊腔。
