Pakutanga kurongeka, semvura yese iri mukati nepamusoro pePasi, kufamba kwemuto uyu, zvisinei nekuwanda kwayo, kunofanirwa kufambiswa zvishoma kana kuti zvachose nemafungu ezuva-solar, kunyanya munguva (¡18.6 years) idzo dziri kunyanya kufarira bepa rino. Gibert et al. ([33]) yakasimbisa kuti kuyerera kwemvura uye chiratidzo chemagetsi chakanyorwa chaive chakabatanidzwa ne electrokinetic phenomena. Nokudaro, kuitira kuti titsanangure kufamba kwemvura kubva pakuona kwefizikiki, isu tiri kubata pano neine harmonic pumping phenomenon (ona [17, 18]). Sezvinoratidzwa muMufananidzo 2, zviratidzo zvemagetsi zvinoramba zvichirekodhwa mumiti zviratidzo zvisiri-zvinomira mupfungwa yakasimba. Izvi zvinodzivirira kushandiswa kwakananga kweFourier shanduko kuona nguva (kureva, masaisai emwedzi wezuva) angaagadzira. Uyezve, kuyerwa vagary dzimwe nguva kunokonzeresa kukanganisa muhurongwa hwekurekodha, zvichikonzera kuti data rirege kuenderera. Ndosaka takasarudza iyo Singular Spectrum Analysis (SSA) nzira yekuongorora zviyero zveRemungol poplar. Iyi nzira inobatsira kudzikisira zvikanganiso zvinogona mukududzirwa kwechinyakare spectra. MuFigure 5 ne6, takaratidza iwo mashanu makuru ekunyepedzera akatorwa kubva mumagetsi angangoita data yepoplar. Ose anofambirana chaizvo nenguva dzemasaisai emwedzi-zuva (P1, K1, S1, Mf, neK2, cf. Tafura yedu 1). Nguva dzatakatora kubva kumasaini emagetsi, ayo anoshanda semaproxies ekuyerera kwemvura, ari mukati me 0.01% yeakaverengerwa mwedzi-solar tidal nguva. Iyi nhanho yekurongeka inoshamisa uye inogona kuwanikwa chete nemagiravhimita anodhura anodhura makumi emamiriyoni emaeuro. Huwandu hwezvinhu zvakabviswa, izvo zvatinotenda kuve zvikamu zvemvura, kazhinji zvinoverengera zvinopfuura makumi manomwe muzana emusiyano wakazara mumasaini akarekodhwa emagetsi. Kana tikaongorora zvakadzama masaini akanyorwa munzvimbo dzakasiyana dzePoplar (mudzi, bazi, hunde) kune yakapihwa tide, tinoona kuti masaisai ane chekuita nemafungu aya haana kuchinjwa nenzira imwechete. Aya amplitude modulations anogona kunge akasiyana zvachose kubva kune mumwe nemumwe, sezvazvakaita kune mafungu uye maelectrodes E1, E8, E32, uye E34 (ona Mifananidzo 4). Nekudaro, ivo vanogona zvakare kuve vakafanana asi vakaganhurwa munguva. Semuenzaniso, tinogona kuona kuti maitiro ezviratidzo akanyorwa ne electrode E7 uye E12 yemafungu akafanana asi akachinjwa nemavhiki maviri (ona Mifananidzo 5). Pasina kupokana, misiyano yeamplitudes uye zvikamu zvakaonekwa mumasaini akanyorwa emuti wePoplar anogona kunge ane hukama nemhinduro yawo yemuviri. Kubva pane zvakaonekwa izvi, takatanga kugadzirisa kwemasvomhu equation ine chekuita nechiitiko chatinotenda kuti ndicho chinokonzera kuyerera kwemvura, tichivavarira kuongorora iyo electrokinetic coefficient inoenderana nePoplar tree, zvakafanana nezvinoitwa mugeophysics yematombo. (ona equation 17). Isu takawana kukosha kwe10 V/Pa, iyo inowanzokwira zvakapetwa kagumi pane kukosha kwakayerwa mumatombo. Zvisinei, zvinofanira kuonekwa kuti miti haisi matombo, sezvatinogona nemufananidzo we xylem geometry muMufananidzo 01, sap flow haina kukanganiswa nemhando ipi zvayo yehuturu, kusiyana nematombo. Uyezve, zvakakosha kusimbisa kuti muto hausi mvura. Mubvunzo wemisiyano yeamplitude modulations pakati penzvimbo dzakasiyana dzemuti wePoplar, pamwe nemubvunzo wehuwandu hwemhedzisiro yedu inoshamisa, watitungamira kuti tibudise kuyedza kumwe chete muna 2019 kuNational Museum of Natural History, asi panguva ino. mhando dzakasiyana dzemiti.
