  1. The stamens and pistil of d. versipelis mature before the flowers open, which shows that dysosma versipelis may be autogamous. d. versipelis produce few fruits. ovaries of d. versipelis seldom develop in nature, but will develop after being pollinated with pollen of another plant

    八角蓮的花在花苞未展開時，雄蕊和雌蕊便已成熟，說明八角蓮的繁育系統為自花受粉，八角蓮座果率非常低，自然狀態下，子房不膨大，人工異交后的子房有膨大現象，說明八角蓮自交低育，有生殖障礙。
  2. The pollen is shed directly on the stigma, resulting in a high percentage of self fertilization.

    花粉直接散落在頭上，因而自花受精百分率高。
  3. 5. the fructified rate by self - pollination is 19. 4 %, and the rate by artificial pollination amounts to 67. 2 %. the best time of pollintion is 24 hours after blooming

    自花受粉結實率為19 . 4 % ，人工輔助授粉結實率達67 . 2 % ，最佳授粉時間在開花后24小時前後。
  4. Selfing is inhibited by genetic self incompatibility and also by the fact that within a single flower the stigma is receptive before the anthes are ready to shed pollen.

    由於遺傳上的自交不親和性以及花中柱頭只能在花粉準備撒粉以前接受花粉，因而防止了自交。
  5. Emasculation the removal of the stamens of a plant before the anthers burst to prevent self - pollination or unwanted crosses to nearby plants

    去雄：在植物花粉囊裂開之前將雄蕊摘除，以防止自花受粉或與鄰近植物的有害雜交。

  7. In sporophytically self - incompatible brassica, three s - linked genes, the pollen ligand scr, stigma receptor slg and srk, have been identified. in addition, four genes ( arc1, thl1, thl2 and mod ) that do not link to s locus have also been found, they are regarded as downstream protein factors of self - incompatibility ( si ) response, however, their biological function is not clear

    在孢子體型自交不親和的蕓薹屬中，已經鑒定出3個主要與s位點緊密連鎖的基因，花粉中的配體scr和柱頭中的受體slg與srk ：另外鑒定出4個不與s位點連鎖的基因arc1 、 thl1 、 thl2和mod ，它們被認為是si反應的下游蛋白質因子，但是對它們的生物學功能了解的還比較少。
  8. Self - compatibility the capacity to self - fertilize. many flowers are capable of self - fertilization if pollination fails, and a few species do it regularly

    自交親和性：指植物自花受精的能力。許多花可以在授粉失敗后進行自花受精，其中有些種類定期進行此過程。

    總共450名患者，每個研究組150名，隨機接受每側鼻孔兩噴的氮卓斯汀噴霧劑、內舒拿或安慰劑噴鼻，接著讓他們在暴露于花粉的8小時的特定時間間隔記錄自己的癥狀。
