Ziziphi iinkalo isakhiwo oganogram i Rosaceae na? Imbali, formula elandela, ubonakala ngokuba yokulandelana ecacileyo:

• CH5L5T∞P∞ - le formula zezi istrawberry, rose zasendle kunye nabanye.

Ixabiso ke ifomula:

• W - sepals zokumakisha.
• L - sembali zokumakisha.
• T - stamens zokumakisha.

• Ca - ukusuka kwisiLatini. uluthi, nto leyo ethetha ikomityi okanye sepals.
• Co - ukusuka kwisiLatini. corola okanye Corolla equlathe n-th inani ezinamagqabi (kulo mzekelo we-5).
• A (androceum) - amalungu eyindoda, okt stamens ...
• G (genoceum) - umzimba ababhinqileyo, oko kukuthi i-kwisingqusho okanye carpels ezinyibilikiswe ...

An into umdla kukuba nangona inja-roses isityalo iluncedo kakhulu, abantu abasuka kwisiqithi Tasmania ngenxa ukwanda kakhulu kwinani bush waqalisa ukuba alwe naye. Wamvusela kubo zeebhokhwe.

Kunzima ukuba nomfanekiso ihlabathi mihla ngaphandle kubukho ezi zityalo. Sinokuthi kokuhluma wabo ubanike amandla okuqhubela phambili uphuhliso zonke izinto eziphilayo wenze indlela ukuqonda nokwazi ngoku.
