This phenomenon is called protogyny, diurnally synchronous dichogamy common when warm weather prevails during flowering.Spraying flowers with sulphur will not reduce the blossom drop.
The high level of genetic variation in the samples of walnut is due to the propagation through seeds, high heterozygosis and dichogamy (Aslantas, 2006; Germain, 2004).
The pecan is a monoecious plant, having separate staminate and pistillate inflorescences on the same plant; however, it has a mechanism so-called dichogamy. This means that the time of pollen release and pistil receptivity may not overlap.
T indicas bisexual flowers exhibit protogynous dichogamy, with flowering occurring in dry season where there is both self- and cross-pollination but the latter is much more effective.
Do dichogamy and herkogamy reduce sexua interference in a self-incompatible species?
(2016) evaluated the floral biology of 'Isabel" cultivar and also observed the absence of dichogamy strategy in flowers.
Therefore, the species has protandry dichogamy. We observed several immature fruits dropped by many plants during their development, indicating abortive events.
Dichogamy, partial self-incompatibility, and inbreeding depression during embryo development may be sufficient to exclude inbred progeny from the seeds of these maples.
Other mechanisms avoiding self-pollination as spatial separation (herkogamy) and temporal separation (dichogamy) (Barrett, 2003; Webb & Lloyd, 1986; Lloyd & Webb, 1986) are hardly related to the stigma type in legumes in part due to the few experimental studies found in literature for this group.
