Mutobiqshavii rastani dar khokhoi nisbatan khushk

Rushdu numui rastaniho ba sharoiti muhiti zisti onho sakht aloqamandi dorad. Juzhoi (elementhoi) alohidai muhiti berunaro (ravshani, harorat, nami, tarkibi khok va gayrahoro) omilhoi ekologi menomand. Binobar on, vobasta ba omilhoi gunoguni ekologii muhiti atrof rastaniho mutobiqathoi gunogun paydo kardaand.

Gunogunii sharoiti muhiti zist boisi gunogunkhelii rastaniho megardad. Binobar on, mo dar vodiyu domanakuhho, teppayu margzorho, dashtu biyobonho rastanihoi bisyorero mebinem, ki baroi dar chunin sharoitho zindagi kardan bo harguna digargunshavii uzvhoyashon khususiyathoi mutobiqati paydo kardaand. Masalan, barghoi tutanjir, guli hasrat va khususan filodendron khele kalon ast. Pas, in rastaniho az joyhoe ovarda shudaand, ki namii farovon doshtaand. Dar haqiqat, vatani in rastaniho beshahoi sernami tropiki ast.

Dar khok to haddi zaruri narasidani nami, yo in ki az had ziyod budani on ba nashunamoi rastaniho tasir merasonad, ohista-ohista (tadrijan) namudi zohiri va sokhti onho tagyir meyobad.

Bargi bisyor rastanihoi mahalli khushk va garmbod vasilahoi mutobiqatie dorand, ki onho boisi kam bukhor gardidani ob meshavand. Masalan, serpashmaki va bo shirai mummonand ruypush budani barg, nisbatan kam budani masomaho va alomathoi digar az jumlai onhoand.

Bargi baze rastaniho, masalan sabr (aloe) va khanjari (agava) purmagzu serob meshavad. Dar in guna bargho ob zakhira meshavad.

Hususan, rastanihoi dashtu biyobon ba sershumor nabudani khelhoyashon dar chunin sharoit (khushki) nigoh nakarda, mutobiqathoi favqulodda gunogun paydo kardaand.
