Yintoni transpiration? Iimpawu nokusetyenziswa kwamanzi kwizityalo

ukusetyenziswa kwamanzi inkqubo yezityalo ezisekwe ngumphunga. Noko ke, kuba nzima iimpawu eziliqela yokwakheka kunye nokomzimba izityalo.

Yintoni transpiration?

Umthamo wamanzi umphunga izityalo, amaxesha amaninzi ngaphezu mali eziqulathwe kule inkcubeko. Ukuziqhelisa yezolimo mihla, umbuzo kwenkcitho eyongayo ukufuma yenye yezona embi kakhulu. Ngokutsho K. A. Timiryazeva, inkqubo transpiration sitsho kukho ingozi oluqhelekileyo nokomzimba. Eneneni, akujongwa kuyimfuneko kwisityalo. Umzekelo, ukuba inkcubeko ikhule phantsi ukufuma ephantsi phezulu, kwimeko yokuqala, transpiration (komphunga) kakhulu ngakumbi. Ngelo xesha linye ukukhula kwezityalo iyafana okanye ngcono kwimeko yesibini.

Transpiration: Ixabiso

Ukusa kumlinganiselo othile, oko kuluncedo kwisityalo. Echaza oko transpiration, kufuneka phawula kuqala umsebenzi zokukhusela. Lolwelo inceda ukukhusela izityalo nobushushu phantsi nakwimitha yelanga. Umzekelo, umahluko lobushushu amagqabi, obunye ukufuma elalixhasa ukuze ukutshintshatshintsha phakathi degrees 7. Oku kubaluleke ngokukhethekileyo inkqubo yefotosinthsis. Inyaniso kukuba xa ebilayo iqala ukutshatyalaliswa chloroplasts. Oku, ehla photosynthesis. Amaqondo obushushu kangangoko na iintlobo 30-33 degrees kuyo. Ngoko ke, yintoni na transpiration? Le ukhuseleko isilimo, ebavumela ukuba sinyamezele kakuhle amaqondo obushushu aphezulu.

Ukuqhubeka ukuhanjiswa kwamanzi

Echaza oko transpiration na, kufuneka sinikele ingqalelo enye impahla yalo entle. Oku kunegalelo intshukumo gqolo kwamanzi ukusuka njengengcambu emagqabini. Idibanisa zonke izinto zonke izityalo zibe omnye. Ndawonye iikhompawundi izimbiwa kunye organic izinto azamazama kunye ukufuma imizimba nenkcubeko. Iqina ngakumbi kukuba inkqubo transpiration, ngokukhawuleza zihamba. Ezinye iikhompawundi ingasiwa kwizisele ngendlela kwisixando sokwenziwa. Transpiration, ngokufutshane ethetha, yinto namafutha yokukhulula izinto.

ngezigaba

Kokuba kucaciswe ukuba transpiration, uyakwazi ukuqhubeka ukuya ingqalelo kweentlobo yayo. Ngesayensi, kukho iindidi ezimbini kuyo. Transpiration kunokuba stomatal kunye cuticular. Kwimeko yokuqala ngumphunga lwenziwa ngalo yokondliwa, wesibini - nalo lonke kumphezulu sheet. Lo mahluko lwaba lolokuqala ngo 1877. Qinisekisa ukuba transpiration nje kuphela ngenxa yokondliwa, kunokuba kakhulu elula. Umzekelo, ungakwazi ukuthatha amagqabi Apple. Kwezi yokondliwa kuphela ukusuka ezantsi. Le umphezulu kufuneka ukunyhibhela Vaseline. Lolwelo iya kuqhubeka nge-Ulobuza, kodwa ubukhulu engaphantsi.

Isakhiwo stomatal uwase

Transpiration ibandakanya:

1. Ukususa amanzi avela iimpahla iindonga yeseli xylem kunye symplast.
2. Lolwelo kwi podustichnye kwisisu kunye namabala intercellular kunye nokuhanjiswa ngakumbi emoyeni engqongileyo ngokusebenzisa noqhoqhoqho stomatal.

Inowuthi nokufuma isizalwane, amandla ngaphantsi kwamanzi esibhakabhakeni. Ukuba ungaphantsi kwe nemingxuma podustichnyh, komphunga kuya kwenzeka ngaphandle. Ulawulo transpiration kunokuba stomatal kunye vneustichnoy. Le yokuqala ikhutshwa phandle ngokuvula nokuvala pores. Xa cover ngokupheleleyo ukuba transpiration kuncitshiswa-90%.

ngamandla

Ubuninzi of transpiration ngemihla iqatshelwe izityalo ezininzi. Noko ke, iintlobo ezahlukeneyo ukusebenza yesityalo yokondliwa kwenzeka ngokwahlukileyo. Xa izityalo umthunzi-ukumelana, imithi, iintlobo ezininzi zengca kunye nezinye izityalo gidrostabilnyh, nto leyo uphawu yommiselo ogqibeleleyo transpiration stomatal, yona iqale ekuqaleni. • Ukuvela komphunga luhlobo ifikelela iphezulu kusasa. Emini, umlinganiselo transpiration lifinyele. ukwanda kwayo waphawula kwakhona ngokuhlwa kunye ekuncipheni lobushushu. Ezo ngamandla uwase kubangela utshintsho diurnal ezingephi uxinzelelo osmotic kunye nomthamo wamanzi emagqabini. Xa gidrolabilnyh (kokuba uyakwazi ukunyamezela ukungalingani ezibukhali kwisiqulatho sokufuma kwisithuba ngosuku) kukho unimodal kunye komphunga incopho emini. Yaye eneneni, yaye kwelinye icala, transpiration ebusuku ncinci okanye oswele ngokupheleleyo.
