| contents | Stigmatic receptivity of peach flowers submitted to heat stress Silvia Carpenedo Maria do Carmo Bassols Rodrigo Cezar Franzon David Hawkins Byrne João Baptista da Silva Agrociencias flowering pollen tubes Prunus persica pollen viability Because of climatic changes, the cultivation of temperate climate plants such as peach in subtropical climates has become a challenge. In these areas, temperatures exceeding 25°C often occur during the pre-flowering and flowering phases. The high temperature causes damages by acting during the early stages of pollen-pistil interaction processes. The objective of this work was to evaluate the stigmatic receptivity of peach flowers at 18°C and 30°C. The pollen adherence was evaluated as well as the germination and presence of pollen tubes in the transmitting tissue of the style. The genotypes responded differently to temperature. ‘Granada,’ ‘Diamante’, and ‘Sensação’ had a stigmatic receptivity that was less affected when flowers were exposed to the higher temperature. Most genotypes showed a reduction in the number of pistils with pollen tubes growing in the style, particularly when pollination was delayed. 2020 artículo científico 1679-9275 https://www.redalyc.org/articulo.oa?id=303062597021 https://www.redalyc.org/journal/3030/303062597021/ https://www.redalyc.org/journal/3030/303062597021/html/ https://www.redalyc.org/journal/3030/303062597021/303062597021.epub https://www.redalyc.org/journal/3030/303062597021/movil 10.4025/actasciagron.v42i1.42450 en http://www.redalyc.org/revista.oa?id=3030 Acta Scientiarum.
