roza n'umweru byera bimara imyaka
Amaroza yijimye kandi yera amara imyaka isanzwe abikwa cyangwa amaroza y'iteka. Izi roza zinyura muburyo bwihariye bwo kubungabunga zibafasha kugumana isura karemano, imiterere, namabara mugihe kinini, akenshi bimara imyaka myinshi. Igikorwa cyo kubungabunga gikubiyemo gusimbuza ibimera n’amazi bisanzwe muri roza nigisubizo cyateguwe, guhagarika neza uburyo bwo kwangiza no kubungabunga ubwiza bwabo.
Ibara ryijimye kandi ryera ritanga ibyiza byinshi. Ubwa mbere, batanga ubwiza burambye, bagumana isura yabo nuburyo bwabo mugihe kinini, bigatuma bahitamo neza kubikorwa byigihe kirekire byo gushushanya. Byongeye kandi, izo roza nindabyo karemano 100% zihingwa mubutaka, zemeza ko zigumana imiterere-karemano nukuri.
Iyindi nyungu nuko amaroza yabitswe adasaba amazi cyangwa urumuri rwizuba kugirango abungabunge. Iyi mikorere itanga uburyo bworoshye kandi buke-bwo gufata neza indabyo zimara igihe kirekire, bigatuma zikwiranye nibidukikije bitandukanye. Byongeye kandi, roza zabitswe ziza muburyo butandukanye bwindabyo, harimo ibara ryijimye kandi ryera, ryemerera impano yihariye kandi ifite akamaro.
Mu buryo bw'ikigereranyo, roza zabitswe zijimye kandi zera zifite akamaro gakomeye k'amarangamutima, bigatuma zihitamo neza mu kwerekana amarangamutima, kwibuka ibihe bidasanzwe, no kwerekana amarangamutima y'urukundo no gushimira. Kamere yabo ihoraho ituma imvugo nubuhanzi bimara igihe kirekire byerekana ibishushanyo mbonera, bigatuma bikundwa mumishinga yo guhanga nkubukorikori, ibihangano byindabyo, hamwe nubushakashatsi.
Muri make, amaroza yijimye kandi yera yabitswe kumara imyaka myinshi atanga inyungu zitandukanye, zirimo kuramba, ibimenyetso, kuramba, no gushimisha ubwiza. Izi ngingo zituma bahitamo gukomeye kubikorwa byo gushushanya no mumarangamutima, ndetse no gutanga impano kubidukikije. Gukomatanya ubwiza burambye, kwerekana ibitekerezo, hamwe nibimenyetso byimbitse byamarangamutima bituma ibara ryijimye ryera kandi ryera ryera rihitamo igihe kandi gikundwa.
