Sabzishi rastaniho va tanzimi on

Nuqtai sabzish. Moddahoi zaruri baroi sabzish

Agar hamai uzvhoi rastani mutadil amal kunand, in manoi onro dorad, ki rastani dar vazi khubi rushdu sabzish qaror dorad. Ba tufayli taqsimshavii hujayrahoi boftai hosilkunanda (bavujudovaranda) va sipas sabzishu makhsusiyatpaydokuni hujayrahoi bavujudomadai organizmi rastani az jihati hajmu (andozayu) vazn kalon shuda, barkamol meshavand. Dar natijai taksimshavii hujayrahoi kambiy boftai hosilkunandai nugi poyaho (nuqtai sabzit) va juzi sabzishi resha navdahoi nav, rsshahon pav ba vujud oma- da, rastani ham ba qad (ba bolo), ham ba poyon va ham ba bar (ba pakhno) nashunamo mekunad va kalon meshavad.

Agar sabzishu kalonshavii uzvhoi odamu hayvonot to yak sinnu soli muayyan davom kunad, azoni rastani (yo sabzishi rastani) dar davomi tamomi umrash (az davrai ba sabzish shuru kardanash to margash) davom mekunad. Dar rastaniho dar davomi hayotashon doimo reshayu navdahoi nav ba nav hosil meshavand. Ba joi barghoi khazonshudayu khazonrekhta boz barghoi nav paydo meshavand. Dar har mavsim gulu mevahoi pukhtarasida pas az adoi vazifaashop khushk gardida, meaftand.

Hamin tavr, sabzishu rushdi doimii rastaniho bo ivazshavii doimii uzvhoi asosi va boftahoi alohidai onho dar uzvhoi doimo- amalkunanda ba kulli vobastagi dorad.

Sabzishu rushdi hamai uzvhoi rastani, ki dar natijai taqsimshavi va kalonshavii (kashidashavii) hujayraho amali megardad, qati idora karda meshavad. Faoliyati nuqtahoi sabzishi resha va poya, kalonshavii barg, juzhoi poya, gulpoya va mevaho bayni yakdigar muvofiqat dorand. Masalan, dar fasli bahor barobari sar shudani nashunamoi poya va mugjaho dar darakhton taqsimshavii kambiy vusat yofta, sabzishi yakvaqtai navdavu tana bo hosil kar- dani solhalqai navbati ogoz megardad.

Inchunin qadkashii (sabzishi) boavji yak uzv metavonad qadkashii uzvi digarro sust kunad yo bozdorad. CHunki dar in holat zakhirai moddahoi gizoi ba yak juzu uzzi muayyani rastani (bazan ba zara- ri digar uzvho) ravona karda shudaast.

Masalan, agar reshai asosi ba darozi boavj sabzida istoda boshad, chunin tanzimi dokhili boisi bozdoshti shokharonii resha megardad. Agar qismi nugii reshai asosi dur karda shavad, on goh, baraks, reshahoi pahlui va ilovagi boavj sabzida, resha sershokha meshavad. In usulro dar kishovarzi vase istifoda mebarand. Dar natijai buridani yak qismi shokhu navdaho metavon mugjahoi khuftaro bedor karda, ba rastany yagon shakli dilkhohro dod. Hamin tavr, tanzimi dokhilii sabzish imkon medihad, ki dar hududi yak rastani baze usulhoi musbati idoraku- nii rushdu inkishofi rastaniho ba kor burda shavand.

Olimon muqarrar kardaand, ki tanzimi ravandhoi sabzishi rastaniho va muvofiqati kori onho ba tufayli dar rastaniho hosil shudani moddahoi makhsus surat megnrad. In moddahoi murakkabi makhsusro “moddahoi sabzishi” yo “gormoni sabzish” me-
nomand. Onho dar hujayrahoi boftai hosilkunanda hosil shuda, metavonand tavassuti hujayrahoi lif harakat kunand va sabzishi juzhoi (uzvhoi) alohidai rastaniro tezonand yo bozdorand.

1. Sabzish chist?
2. Sabzishu rushdi rastaniho chi tavr amali megardad?
3. Qadkashii rastaniho az qadkashii odamu hayvonot chi farq dorad?
4. Tanzimi sabzish chi ahamiyat dorad?
5. Tanzimshavii sabzishro bo kadom misolho isbot kardan mumkin ast?
6. Moddahoi tanzimii sabzishro chi menomand?
