METHOD FOR OVERCOMING THE PASSION FRUIT SELF-INCOMPATIBILITY

open access: yesRevista Brasileira de Fruticultura
The methodology of self-pollination of passion fruit flowers at anthesis after stigma excision was proposed. This method was compared with self-pollination procedures at anthesis and at the stage of flower bud.

Pollination deficit in open-field tomato crops (Solanum lycopersicum L., Solanaceae) in Rio de Janeiro state, Southeast Brazil

open access: yesJournal of Pollination Ecology, 2013
More than 70% of world’s crops benefit from biotic pollination, and bees are their main pollinators. Despite the fact that some of these insects have been broadly studied, understanding the interactions between plant crops and their pollinators with a ...

The Evolution of Self-Pollination in Clarkia xantiana [PDF]

open access: yesEvolution, 1965
The evolutionary effects of outbreeding and inbreeding systems have caused considerable interest and speculation over the years and their influence in changing gene frequencies has been formalized mathematically (see Fisher, 1949; Wright, 1921). A large body of data is available on the genetical basis of the sex and incompatibility mechanisms promoting

The effect of sheltered load on reproduction in Solanum carolinense, a species with variable self-incompatibility [PDF]

open access: yes, 2009
In previous studies, we have investigated the strength of self-incompatibility (SI) in Solanum carolinense, a highly successful weed with a fully functional SI system that inhabits early successional and other disturbed habitats.

Seeds of change: The impact of Ethiopia's direct seed marketing approach on smallholders' seed purchases and productivity

open access: yesAmerican Journal of Agricultural Economics, EarlyView.
Abstract While multiple factors explain low adoption rates of improved varieties by small‐scale farmers in sub‐Saharan Africa, a key supply‐side constraint is the limited availability of seed embodying new traits in the volume, quality, price, and timeliness required by farmers. This constraint is partly attributable to classical failures in the market

Efficient haploid production on 'Wilking' mandarin by induced gynogenesis [PDF]

open access: yes, 2015
Seedlessness is a major criterion for the citrus fresh fruit market. Therefore, triploid breeding appears very promising for the selection of new citrus cultivars.

Local Specific IgE Levels Can Predict and Monitor the Therapeutic Response to Subcutaneous Immunotherapy With House Dust Mite

open access: yesInternational Forum of Allergy &Rhinology, EarlyView.
ABSTRACT Background Identifying predictive and monitoring biomarkers for allergen immunotherapy response is crucial for enhancing clinical efficacy. This study aims to investigate the systemic and local levels of immunoglobulins and identify potential biomarkers in house dust mite (HDM) allergic rhinitis (AR) patients who are undergoing subcutaneous ...
