Bonke abamele izilwane zasendle balungiselela ubusika ngendlela yabo. Izinhlobo zokuphila zezitshalo zinokungafani kobusika. Izitshalo zamakhemikhali zonyaka ziyafa lapho kuqala isimo sezulu esibandayo bese zishiya imbewu lapho kuzokhula khona amahlumela amasha. Ngakolunye uhlangothi, utshani obungapheli bufihla ama-bulb, izilimo eziyizigaxa noma izimpande ngaphansi komhlaba, kuthi ingxenye yomhlabathi ife. Ezinye izinhlobo zihlala ziluhlaza ebusweni bomhlaba, kuthi ebusika zifihlwe yiqhwa kuze kufike intwasahlobo. Bangakwazi ukuthuthukisa iziqu futhi bakhule amaqabunga, abesabi amaqhwa amakhulu.
Ebusika, izihlahla ezibanzi kanye nezihlahlana kuchitha amaqabunga awo bese kugxumela esimweni sokulala esihlala kuze kube maphakathi, futhi kwesinye isikhathi kuze kuphele nobusika. Lezo zihlahla ezinamagxolo aminyene zibekezelela kahle ubusika. Amahlumela ezitshalo ezinokhuni anezikali zokuzivikela futhi asezingeni eliphakeme ukusuka emhlabathini, okuwavumela ukuba amelane namazinga okushisa aphansi. Ingozi ibonakala kuphela emagatsheni amancane. Ebusika, izihlahla ezifihlekile zisesimweni sokulala komzimba. Bavuka sekuqala imfudumalo. Ososayensi bachaza ukuphikelela kwezinhlobo ezahlukahlukene zezimbali ngokuthi, ngokuya ngombuso wamazinga okushisa, baba nezinguquko ezingaphakathi kwamaseli.
Ama-conifers asebusika
Kuyaphawuleka ukuthi izihlahla zikaphayini ziziphatha ngendlela ehlukile kunezinhlobo ze-broadleaf. Babekezelela noma ibuphi, ngisho nobusika obunzima kakhulu, neqhwa nomswakama ophezulu. Isembozo seqhwa sihlanganisa izimpande zemithi kanye nehlathi phansi. Akusilo iqhwa elinomphumela omubi ezinalweni, kepha ukungabi khona komswakama. Ngenkathi ebandayo, isiqu nezimpande zezihlahla zikaphayini "zilala", kepha zidinga umswakama, onqwabelana ngezinaliti. Zimbozwe ngefilimu ekhethekile evikelayo evimbela ukuhwamuka kwamanzi ngokweqile. Lokhu kubenza bakwazi ukushintsha amaqabunga kancane kancane ngokuhamba kwesikhathi. Futhi, i-stomata ivalwe ngento ekhethekile, ngakho izinaliti azifi ngisho nasemazingeni okushisa aphansi kakhulu. Ebusika, amanzi avela ezimpandeni awahambi kahle aye emagatsheni nakwezinye izingxenye, futhi uma zingekho izinaliti emagatsheni, zingaphuka.
Ngokuqondene nezinye izinhlobo zezitshalo, ezinye zazo zingasebusika ngamaqabunga aluhlaza. Lezi yi-lingonberry, i-heather, isithandwa sasebusika, eliphakathi kwe-linnea nenyakatho. Ngenxa yalokhu, akusilo iqhwa okuyisici esibi kakhulu ebusika, kepha isithwathwa nomswakama onganele, kepha zonke izitshalo ziyakwazi ukubekezelela inkathi ebandayo ngokujwayelekile ngaphandle kwezinkinga.
