Not from Solanaceae, but tangentially related. (It is studies like this one that set people like me to wonder at the selfing/crossing problem:)) possibly even a low-hanging fruit here:))
C. Montaner , E. Floris & J. M. Alvarez (2003): Study of pollen cytology and evaluation of pollen viability using in vivo and in vitro test, in borage (Borago officinalis L.) , Grana, 42:1, 33-37:
...It was stated that [borage’s] pollen is difficult to germinate in vitro, it loses viability shortly after anther dehiscence and in the case of incompatible pollinations pollen tubes tend to be inhibited on the stigmatic surface (Mulcahy & Mulcahy 1983). Ghorbel and Nabli (1998) said that borage pollen remained dehydrated after self-pollination, like a sign of self-rejection. However, Crowe (1971) affirmed that the incompatibility reaction occurs after fertilization although our data (Montaner et al. 2000 a) demonstrated that there is not self-incompatibility and incompatible crosses have not been detected...
I mean, what the..? Is it, or is it not, self-incompatible?.. Although I must say that I haven’t looked on articles citing this one.
