Kugeza ubu, abahanga bemezaga ko amazi yatembaga mu biti ku buryo bumwe buzwi nka osmose. Kuri ubu bavumbuye ko ibiti n’amashami yabyo bivoma amazi mu butaka byifashije imizi yabyo bikayageza mumashami no mumababi nkuko umutima wacu usuka amaraso mumubiri wacu!
Itandukaniro gusa hagati y’imitsi yacu n’igiti nuko igiti gitinda cyane, “gikubita” hafi buri masaha abiri, kandi aho kugenga umuvuduko w’amaraso nk’umutima w’umuntu, igiti cyo kigenga umuvuduko w’amazi “umuvuduko w’umutima w’igiti”.
András Zlinszky wo muri New Scientist yabwiye New Scientist ati: “Twabonye ko ibiti byinshi bigenda bihinduka buri gihe mu miterere, bigahuzwa mu gihingwa bikubiyemo impinduka zigenda zihinduka ku muvuduko w’amazi.”Mu bushakashatsi bwe bwo mu 2017, Zlinszky na mugenzi we Anders Barfod bakoresheje Lazeri yo ku isi kugira ngo bakurikirane amoko 22 y’ibiti kugirango bamenye imiterere y’ibiti byabo.
Ibipimo byafatiwe muri pariki nijoro kugirango hirindwe izuba n’umuyaga nk’ibintu bigenda mu biti. Mu biti byinshi, amashami yimuka nka santimetero buri masaha abiri. Nyuma yo kwiga ibikorwa by’ibiti nijoro, abashakashatsi batanze igitekerezo kijyanye n’ubusobanuro bwimikorere y’ibiti. Bizera ko icyerekezo ari ikimenyetso cyerekana ko ibiti bivoma amazi mu mizi yabyo.
Zlinszky na Barfod basobanura ibitekerezo byabo mubushakashatsi bushya bwasohotse mu kinyamakuru Plant Signaling and Behavior.
Bagira bati: “Muri physiology ya kera y’ibimera, inzira nyinshi zo gutwara abantu zisobanurwa nk’imigezi ihoraho hamwe n’imihindagurikire idahwitse uko ibihe bigenda bisimburana.” “Nta tandukanyirizo hamwe n’ibihe bitarenze amasaha 24 bifatwa cyangwa bisobanurwa na moderi y’ubu. “
Ariko abashakashatsi ntibarasobanukirwa neza n’uburyo icyerekezo cy’ umutima w’igiti utera werekezamo gikora. Bashobora kuba bavuga ko umutiba w’igiti unyunyuza amazi gahoro gahoro, ukayasunika hejuru unyuze kuri xylem (imijyana y’igiti) iyi sisiteme akazi nyamukuru ni ugutwara amazi n’intungamubiri kuva mumizi kugera kumashami n’amababi. Ibi rero aba bashakashatsi bakabigereranya n’uburyo umutima usakaza amaraso mu mubiri wa muntu binyuze mumijyana n’imigarura.
