Yintoni phanerophyte?

Izityalo zaqala ukuvela kwazo ngaphezulu kweminyaka engama-200 yezigidi eyadlulayo. Ngalo lonke uguquko lwabo, baqhele iimeko ezahlukeneyo zemozulu. Ezinye zazo zezona zitsala umdla wethu namhlanje, kuba zikwazile ukwandisa ixesha lokuphila kwazo de zigqithe kwiwaka leminyaka. Ezi zityalo zaziwa njenge phanerophytes.

Ngaba uyafuna ukwazi ukuba zeziphi iimpawu zayo? Ewe uyazi: qhubeka ufunda ukwazi yonke into malunga nabo.

Yintoni phanerophyte?

Izityalo zePhanerophytic Zonke ezo zinto zinamandla (imithi emikhulu, izihlahla, iingcongolo, okanye ingca, njengemithi yesundu) ezinamahlumelo atshintshayo ngaphezulu kweesentimitha ezingama-20-50 ukusuka kumgangatho womhlaba, okanye ukuqala kwesiqu kwezo ntlobo zinyukayo.

Ngokobungakanani, ezi biotypes zahlukile:

• I-Nanofanerophytes (ngaphantsi kwe-2m): njenge UGenista scorpius.
• Microfanerophytes (phakathi kwe-2 kunye ne-10 yeemitha): njenge IJuniperus turbinata.
• I-Mesophanerophytes (phakathi kwe-10 kunye ne-22 yeemitha): njenge I-Quercus suber.
• Macro-phanerophytes (phakathi kwama-22 nama-50 eemitha): njenge enzonzobileni alba.
• Megaphanerophytes (ngaphezulu kweemitha ezingama-50): njenge Sequoiadendron giganteum.

Kutheni le nto… injani?

Ezi ntlobo zezityalo zikhetheke kakhulu kwaye ziyamelana, kodwa ngenxa yeso sizathu baye "baphoqelelwa" ukuba bavumelane nemeko-bume ezingasoloko zifanelekile. Umzekelo, ukuba sithetha ngequoia enkulu, ikhonapho enokuphila ukuya kwiminyaka engama-3200 XNUMX, kunganzima kakhulu ukufikelela kwiminyaka engummangaliso ngeli lixa ipheleleyo ukuba ibingengotshintsho lwayo kubude obuthile ukusuka umhlaba.

Ngoba? Kuba Ngexesha elingathandekiyo lokukhula, kwimeko yakhe ikhephu ligubungela inxalenye yomboko. Ukuba loo ndawo yayinamahlumela, baya kusokola kwaye bekunokuba nzima ukuba bavuke entwasahlobo.

Ukuba sithetha ngezinye izityalo, elona xesha lokukhula kunokuba lihlobo, kuba ihlala ingqamana nelona xesha lomileyo lonyaka.

Inomdla, akunjalo?
