Ngakhale kuti lingaliro la mndandanda uwu ndilo kuthandiza kuthandizira zomera, pali kusagwirizana pa kuyenera kwa kugawira zomera mu magulu awiriwa. Zina mwa zizolowezi zina zomwe zimagwiritsidwe ntchito zingagwirizane. Mwachitsanzo, pali zosiyana ndi ziwalo za maluwa, makonzedwe a mitsempha, minofu mu tsinde, mungu, ndi chitukuko cha mizu. Ndizo kwa a botanist kuti akambirane. Kwa alimi, ndibwino kuti muzindikire kuti mungapezebe zomera zomwe zasankhidwa motere.
Dikirani, pali Zambiri
