- hypothesis : n. （pl. -ses ）1. 假設；假說。2. 【邏輯學】前提。
-
The chemiosmotic hypothesis describes the stomatal opening as a process in which the osmotic materials, mainly potassium, accumulate in guard cells, and as a result of the increase of osmotic pressure and the absorption of water into guard cells the stomata are driven to open. the energy for trans - membrane transport of k + is the hyperpolarized potential across plasmalemma, which is established by the proton extrusion
化學滲透假說認為氣孔開放是由外來滲透物質（主要是k ~ + ）等在保衛細胞中的累積造成的滲透壓上升所致，而離子跨膜運輸的動力是誘導氣孔開放的因子引發的保衛細胞向胞外泵出質子所造成的超極化膜電位。 -
However, it is hard to find out direct evidences for the accumulation of foreign k + in guard cell vacuoles for stomatal opening to satisfy the chemiosmotic hypothesis
然而該假說缺乏k ~ +等物質在滲透調節的關鍵部位? ?保衛細胞液泡中積累或耗散的直接證據。
