原來這不是生鏽,是植物的這些細胞裡存在的酚類物質發生了化學變化的緣故.本來細胞裡酚氧化酶與酚類底物是分開存放的,但若組織細胞受損或衰老,結構解體時,酚氧化酶便有機會與酚類底物接觸而促使底物氧化成棕褐包的物質.

Original this is not rusts, is the phenol class matter which in plant's these cells exists has had the chemical change reason In the original cell the phenol oxidation □separates depositing with the phenol class substrate, but if the organization cell suffers injury or is senile, when structure disintegration, the phenol oxidation □then has the opportunity and the phenol class substrate contact urges the substrate oxygen to turn into the brown brown package the matter.

もとはこれはさびるのではありませんて、植物のこれらの細胞の中で存在のフェノール種類の物質の化学変化が発生した原因です.本来の細胞の中でフェノールは酸化しますか？フェノール種類の底の物と別れて保管したので、あるいはもししかし細胞を組織するのが損なうならば老衰して、構造の解体する時、フェノールは酸化しますか？機会があってフェノール種類の底の物と底の物に成棕の褐色の包みの物質に酸化するように促すことに接触します.

i hope i will help u la~^^

These are not rusts, rather, they are caused by a chemical reaction associated with phenols that occurs within the plant cells. Originally, there are separate storage compartments for phenol oxidase and phenol-based compounds, but when a plant cell gets damaged or ages, phenol oxidase will have the opportunity to get in contact with phenol-based compounds in the other compartment. This results in an increased rate of oxidation, turing phenol-based compounds into a brown colored product as a result of the reaction.
