Mu myaka yashize, umubare w’ingese zera wafashwe ku ngufu wabaye mwinshi cyane, bigira ingaruka zikomeye ku bwiza bw’ingufu.
Ingese yera yera irashobora gufata ingingo zose ziri hejuru yubutaka mugihe cyo gukura kwi gufata kungufu, cyane cyane yangiza amababi nigiti. Iyo amababi yanduye bwa mbere, uduce duto duto duto twatsi hamwe na halo yumuhondo bizagaragara imbere yibibabi, bigenda bihinduka umuhondo buhoro buhoro. Inkovu zera zisa n'inkovu zizagaragara inyuma yamababi. Iyo inkovu zimenetse, ifu yera izasohoka. Mugihe gikomeye, indwara Amababi ahinduka umuhondo akagwa. Hejuru ya pedicel yanduye yarabyimbye kandi iragoramye, ifata ishusho ya "robine", kandi urugingo rwindabyo rwangiritse. Amababi arahinduka, araguka, ahinduka icyatsi namababi asa, kandi ntikuma igihe kinini kandi ntabwo gikomeye. Ibikomere ku giti ni inkovu zera ndende, kandi ibikomere byabyimbye kandi bigoramye.
Hariho ibihe bibiri byo hejuru kuva kumera kugeza kumurabyo wuzuye. Indwara ikunda kwibasirwa kenshi nubushyuhe buke nubushuhe bukabije bwibidukikije. Iyi ndwara ikunze kugaragara mu bibanza bifite ubutaka buke, amazi mabi, ubutaka buremereye, kuvomera cyane, itandukaniro ryinshi ry’ubushyuhe hagati y’ijoro na nijoro, ikime cyinshi, no gukoresha ifumbire ya azote ikabije.
Kwirinda no kuvura iyi ndwara birashobora guhera ku ngingo zikurikira. Ubwa mbere, birakenewe guhitamo ubwoko butarwanya indwara. Ubwoko bwa sinapi na kungufu birwanya cyane, bigakurikirwa nubwoko bwimyumbati. Ubwoko bw'imyumbati irashobora kwandura indwara kandi irashobora gutoranywa ukurikije imiterere yaho; icya kabiri, birakenewe guhinduranya hamwe nibyatsi byimyaka 1 kugeza 2 cyangwa guhinduranya ibihingwa hagati yumwuzure n amapfa; icya gatatu, birakenewe kurandura burundu indwara.
