【問題】: 下列何種情形下,來自S1S2植物的花粉可對S2S3的花成功完成授粉 A If you used pollen from a carpelate flower, to fertilize a staminate flower, it would be successful. B If the plants used sporophytic self-incompatibility, half of the pollen would be successful. C If the plants used gametophytic self-incompatibility, half of the pollen would be successful. D Pollen from an S1S2 plant can never pollinate an S2S3 flower. 【問題起因】: 做題目看到的 【個人看法】: 我覺得是C,但是不太確定,請大家給些意見,謝!!! -- ※ 發信站: 批踢踢實業坊(ptt.cc) ◆ From: 140.112.247.238
