Autohomogamy
Definition
A biological phenomenon and reproductive mechanism found in certain plant species or lower organisms, characterized by the simultaneous maturation of male and female sexual organs (androecium and gynoecium) within the same flower or individual, directly facilitating mandatory self-fertilization. This strict temporal correlation guarantees reproductive success in isolated environments but severely limits the genetic diversity of the offspring.
Bilingual Equivalents

Contextual Usage Examples
RO: Acest tip de autofecundare extremă este declanșat de o autohomogamie strictă, polenul fiind eliberat exact când stigmatul devine receptiv.
EN: This type of extreme self-fertilization is triggered by a strict autohomogamy, the pollen being released exactly when the stigma becomes receptive.
RO: În lipsa insectelor polenizatoare, planta apelează la autohomogamie ca strategie de supraviețuire evolutionistă pentru a produce semințe.
EN: In the absence of pollinating insects, the plant resorts to autohomogamy as an evolutionary survival strategy to produce seeds.
RO: Studiul genetic a relevat că un nivel ridicat de autohomogamie în cadrul populației izolate a duh la o creștere masivă a homozigotismului.
EN: The genetic study revealed that a high level of autohomogamy within the isolated population led to a massive increase in homozygosity.
Idioms & Phrases

RO: Procentul de flori dintr-o cultură care realizează polenizarea internă datorită suprapunerii perfecte a perioadelor de fertilitate ale celor două sexe.
EN: The percentage of flowers within a crop that achieve internal pollination due to the perfect overlap of the fertility periods of both sexes.
Autohomogamie florală obligatorie / Obligate floral autohomogamy
RO: Mecanism biologic strict în care structura anatomică a florii împiedică fizic polenul străin, impunând doar sincronizarea și fecundarea proprie.
