Harakati rastaniho

Agarchande rastaniho dar yak joy muqimy sabzand ham, vale vobasta ba tasiri omilhoi muhiti beruna va gayraho dar ravandi rushdu inkishofashon harakathoi gunoguni uzvhoi ruizamini va zerikhokii onhoro mushohida kardan mumkin ast. Qismi ziyodi harakati rastani — sabzishi meboshad. Dar natijai sabzishi poyavu navdaho rastaniho botadrij ba tarafhoi gunogun sabzida, dar fazo mavqei muayyanero ishgol mekunand.

Ba juz harakathoi nisbatan sustu botadrij, boz harakathoi nisbatan bosurati uzvhoi alohidai rastaniho, vobasta ba omili tasirkunanda, mamuland. Masalan, bargu poyai bisyor rastaniho (anjibar, nastursiya (lodan), gul yo tudagul (masalan, tudaguli (sabadaki) oftobparast) ba tarafi ravshani faolona harakat karda, mesabzand.

Malum meshavad, ki chunin harakat yo mayli boavji rastaniho ba in yo on jonib odatan ba sabzishi nobarobari dumchahoi barg yo gulpoya vo- basta meboshad. Zero hujayrahoi tarafi nisbatan toriki dumchai barg yo gulpoya bosurat taqsim shuda, kalon meshavand (nisbat ba hujayrahoi tarafi ravshani onho). Dar natija tarafi toriki dum- chai barg yo gulpoya nisbat ba tarafi ravshani onho daroztar shuda, khamshavi ba tarafi ravshani ruy medihad.

Inchunin, dar rastanihoi buttagiyu darakhti khotambandii barg mushohida karda meshavad . Tufayli in hodisa bargho dar navda tavre joygir meshavand, ki ravshani ba aksari onho dastras boshad.

Ba chunin sabzishi nobarobari hujayrahoi rastani, ki boisi harakat yo ruygardonii in yo on uzvi onho megardad, ba juz ravshani boz digar omilhoi chunin tasirdoshta (harorat, nami, moddahoi madanii tarki- bi khok va gayraho) sabab meshavand. Masa- lan, reshahoi javon ba tarafi sernam yo ba samte, ki namakhoi madaniash ziyod ast, sab- zida harakat mekunand.

Bo tasiroti tagyi- rothoi shabonaruzii ravshani va harorati havo gul yo tudaguli rastaniho dar soathoi muayyani shabonaruzi kushoda va yo pushida meshavand. Dar namudhoi gunoguni rastaniho kushodashavii gul yo tudaguli onho dar soathoi gunoguni ruz surat megirad. CHunin tagyiryobii holati gul (kushodashavy yo pushidashavii on) dar aksa- ri mavridho ba sabzishi nobarobari tarafhoi (dokhili va beru- nii) kosabargu gulbarg vobasta ast. In khususiyati rastanihoi gul- dorro ba inobat girifta (dar soathoi muayyani ruz kushoda yo pushidashavii guli rastanihoi gunogunro), vaqtro aniq kardan mumkin ast. YO bo tavri digar, onhoro chun “soathoi biology” is- tifoda burdan mumkin ast. Baroi in dar maydonchai maktab ras- tanihoi dar soathoi gunoguni ruz gulashon kushodashavandaro gird ovarda, bo tartibi muayyan parvarish kardan lozim ast.

Harakati sabzishii rastaniho chi tavr surat megirad?Inchunin, dar rastaniho harakati bosurati (tezi) baze uzvho malumand, ki ba sabzishi on uzvho aloqamand nestand. In kheli harakatho ba nihoyat tez tagyir yoftani mikdori ob dar uzvhoi dakhl- dor vobasta ast. Masalan, bo surati tez (qarsoszanon) kushoda- shavii gilofakmevaho yo in ki barobari dast rasondan ba mimozai sharmgin barghoyash bo surati tez ba poyon kashol meshavand MYU .
