Oyimira nyama zonse zakutchire amakonzekera nyengo yozizira m'njira yawoyawo. Mitundu yamoyo yazomera imakhala ndi nyengo yozizira. Zomera zapachaka zokhazokha zimafa ndikayamba nyengo yozizira ndikusiya mbewu zomwe mphukira zatsopano zimera. Komanso, udzu wosatha amabisa mababu, tubers kapena mizu pansi, ndipo gawo lapansi limafa. Mitundu ina imakhalabe yobiriwira padziko lapansi, ndipo nthawi yozizira imabisala ndi chisanu mpaka masika amabwera. Amatha kukhala ndi zimayambira ndikukula masamba, saopa chisanu choopsa.
M'nyengo yozizira, mitengo yotambalala ndi zitsamba zimatsanulira masamba ake ndikulowa m'malo ogona omwe amakhala mpaka pakati, ndipo nthawi zina ngakhale kumapeto kwa dzinja. Mitengo yomwe ili ndi makungwa akuluakulu imalekerera nthawi yozizira bwino. Masamba a zomera zake amakhala ndi masikelo oteteza ndipo amakhala pamtunda wokwera kuchokera pansi, womwe umawathandiza kupirira ngakhale kutentha pang'ono. Vutoli limangowonekera nthambi zazing'ono zokha. M'nyengo yozizira, masamba amitengo amakhala atagona. Amadzuka ndikutentha. Asayansi akufotokoza kulimbikira kwa mitundu yosiyanasiyana ya zomera chifukwa chakuti, kutengera kutentha, amasintha pazitsulo.
Ma conifers achisanu
Tiyenera kudziwa kuti mitengo ya paini imachita mosiyana ndi mitundu ya broadleaf. Amalekerera chilichonse, ngakhale nyengo yozizira kwambiri, ndi chisanu komanso chinyezi chambiri. Chipale chofewa chimakwirira mizu yamitengo ndi nthaka. Si chisanu chomwe chimasokoneza singano, koma kusowa kwa chinyezi. M'nyengo yozizira, thunthu ndi mizu ya mitengo ya paini "amagona", koma amafunikira chinyezi, chomwe chimasonkhana mu singano. Amakutidwa ndi kanema wapadera woteteza kuti madzi asamasanduke nthunzi. Izi zimawathandiza kusintha masamba pang'onopang'ono pakapita nthawi. Komanso, stomata imasindikizidwa ndi chinthu chapadera, chifukwa chake singano sizimafa ngakhale kutentha kwambiri. M'nyengo yozizira, madzi ochokera kumizu samayenda bwino kupita kuma nthambizo ndi magawo ena, ndipo ngati kulibe singano pama nthambi, amatha kuthyoka.
Ponena za mitundu ina yazomera, zina zimatha nyengo yozizira ndi masamba obiriwira. Awa ndi lingonberry, heather, okonda nyengo yozizira, peyala ndi linnea kumpoto. Zotsatira zake, si chipale chofewa chomwe chimakhala choipa kwambiri m'nyengo yozizira, koma chisanu komanso chinyezi chosakwanira, koma zomera zonse zimatha kupirira nyengo yozizira nthawi zambiri popanda mavuto.
