WebEmergence, Elongation, and Senescence of Maize Silks. In maize (Zea mays L.), duration of silk receptivity to pollen is limited after silks emerge from the husks. Whether this loss in receptivity reflects senescence of the entire ear or individual pistillate flowers is not known. Therefore, we examined the relationships between emergence ...

Senescence and receptivity of maize silks

WebMay 24, 2024 · Plant flowers have a functional life span during which pollination and fertilization occur to ensure seed and fruit development. Once flower senescence is initiated, the potential to set seed or fruit is irrevocably lost. In maize, silk strands are the elongated floral stigmas that emerge from the husk-enveloped inflorescence to intercept airborne … WebJul 1, 2024 · We show here that silk senescence is positively correlated with termination of receptivity in different maize inbred lines in both the glasshouse and in the field. We also find evidence for PCD as being responsible for tissue degeneration at the silk strand base that is correlated with the senescence-induced termination of silk function.
