Resha dar hayoti rastaniho ahamiyati avvalindaraja dorad. Rastaniho ba vositai reshaashon dar khok ustuvor joygir shuda, az on ob va moddahoi madanii baroi hayotashon zaruriro megirand. Baroi isboti in guftaho tajribahoi gunogun kumak merasonand. Agar yagon rastanii dar reg yo arramaydai namnok parvarish kardashudaro girifta, bo reshaash ba dokhili probirka yo zarfi shishagini obdor dokhil kunem va sathi boloii obi zarfro bo qabati tunuki ravgani rastanigi faro girem, pas az yak-du ruz mebinem, ki hududi obi qaydkardashuda khele poyon faromadaast. In nishon medihad, ki rastani bo vositai reshaash obro jabbida ba bolo ba jonibi bargho ravona kardaast.
YO in ki rastanii khonagi -hinogul yo navniholi se-chorhaftainai oftobparast yo lubiyoro, ki peshaki dar tubak sabzonda shudaast, tavre meburem, ki az bekhi poyaash 3-4 sm boqi monad. Ba boqimondai poyai buridashuda naychai rezinii daroziash 3 sm budaro mepushonem. Ba naychai rezini kame ob rekhta nugi onro bo naychai shishagini daro- ziash 20-25 sm, ki ba shakpi orinjak kaj kunonda shudaast (ba rasmi ‘J- nigared), payvast menamoem. Badi yakchand muddat ob bo naycha bolo mebaroyad va ba berun merezad. Savole paydo meshavad, ki on ob az kujo paydo shud? In obro resha az khok jabbida megirad. Sipas, ob ba tufayli boftahoi guzaronandai (raghoi) resha ba boqimondai poya guzashta, ba naycha dokhil meshavad. Baroi on, ki obi ba naycha dokhil- shuda ba bolo harakat kunad, quvvai muayyane lozim ast. In quvva yo fishorro fishori reshagi menomand. Mahz ba tufayli in fishori reshagi ob az resha ba poya guzashta, ba bolo harakat mekunad.
Agar in tajribaro idoma doda, ba khoki tubaki rastanii poyaash buridashuda obi shirgarm rezem, ob bo zudi tavassuti naychai shishagin bolo baromada, ba berun merezad. Baraks, agar obi haroratash nihoyat khunuk rekhta shavad, ba bolo harakat kardani ob qat megardad. Hamin tavr, obro jabbidani resha ba harorat niz vobasta ast. Resha obi khunukro bad mejabbad. Az in ru, ba rastani obi khunuk do dan mumkin nest.
CHunin hodisaro bahoron hangomi buridani shokhu navdai baze darakhton (tok, tus, zarang) niz mushohida kardan mumkin ast. CHunonchi, dar vaqti shiradav buridani navdahoi tok az onho dar muddati chandin ruz ob merezad, ki in holat niz az mavjudiyati fishori reshagi darak medihad.
Rastaniho be ob sabzish va nashunamo karda nametavonand. Zero tamomi faoliyati hayotii onho faqat bo ishtiroki bevositai ob meguzarad. Masalan, rastanihoi galladonagi baroi hosil kardani yak kilogramm moddai khushk taqriban 300-400 litr obro istifoda mebarand. Hususan, rastaniho dar davrai boavji nashuna- moyashon ba ob beshtar ehtiyoj dorand. Dar vaqti ba pukhtan shuru kardani mevaho ehtiyoji rastaniho ba ob nisbatan kam meshavad. Dar surati obmonii az had (meyor) ziyod mevaho der mepazand. Bar zammi in, in holat boisi boavj sabzidani navdahoi navbanav megardad. In navdahoi hosilshuda chubin shuda natavonista, zimiston onhoro khunuk mezanad.

Dar vaqti salqinii havo khok namiro khub- tar jabbida megirad va ob kamtar bukhor meshavad. Inchunin, ba rastani naboyad zud-zudu kam, balki der-deru bisyor ob dodan behtar ast. Hangomi bo obposhak ob dodani tubaki gul yo palchahoi nazdihavligi obposhakro boyad tavre kor farmud, ki jarayoni ob khokro nashuyad 36 .
