Spraying water-soluble particles on the crop. 作物に水溶性微粒子を散布した実験

Short Introductions of /our papers/ Komatsuna plants were grown and exposed to ammonium sulfate (((NH4)2SO4), AS) submicron particles for 16 days (22.5 µg m−3 per day) in phytotrons. The amount of particles deposited on the leaf  decreased over time, because AS particles deposited on the leaf deliquesced, allowing ions such as SO42− in the solution… Continue reading Spraying water-soluble particles on the crop. 作物に水溶性微粒子を散布した実験

Does the leaf structure prevent the deposition of airborne particles? 葉の構造は大気中微粒子の付着を防止するのか?

Other "intro" of papers from our lab >> /tag/paper/ Our results suggest that epicuticular wax crystals affect distribution of particles on needles. Densely distributed epicuticular wax crystals might prevent the deposition of sub-micron particles on the surfaces of needles to retain the function of stomata. 電界放出型走査電子顕微鏡(FE-SEM)によるスギ(代表的な針葉樹種)の葉表面に人工的に散布されたサブミクロンサイズの炭素系粒子の局在を調べました。気孔の機能を保持するために、密に分布されたエピクチクラワックス結晶は、気中からの微粒子の付着を防止する役割があるかもしれません。 Elucidation of the mechanism of adsorption of particles suspended in the… Continue reading Does the leaf structure prevent the deposition of airborne particles? 葉の構造は大気中微粒子の付着を防止するのか?
