Self-pollination caused inbreeding depression in wet and dry weight or seed number in some Stachys setifera genotypes.
Verbatim
e0“This study examined the effects of self- and cross-pollination on agro-morphological traits, aerenchyma formation, and essential oil composition in Stachys setifera”
e2“Self-pollination led to contrasting effects: it enhanced traits such as hundred-seed weight and essential oil content in some genotypes, while causing inbreeding depression in wet and dry weight or seed number in others”

Other claims from this paper (8)
- Intervention effect Self-pollination enhanced hundred-seed weight and essential oil content in some Stachys setifera genotypes, compared with cross-pollination.
- Observation Stachys setifera genotypes differed significantly in biomass, seed yield and essential oil content.
- Observation The dominant essential oil constituents of Stachys setifera were geraniol, linalool, hexadecenoic acid, tetradecanoic acid and geranyl acetate.
- Association Inbreeding influenced essential oil compounds in both directions across genotypes.
- Association Aerenchyma traits were significantly higher in parents than in progenies of Stachys setifera.
- Association Root and rhizome aerenchyma showed strong associations with yield components and essential oil content.
- Observation Rahnan, Ji Shir, Rodehen and Dastgerd were identified as Stachys setifera genotypes with high biomass and essential oil production.
- Mechanism An increase in aerenchyma area and number appears to enhance the medicinal potential of Stachys setifera.
