as per my knowledge its rice crop. because pistillate in rice are highly dependent on temperature...
tomato pistilate length is depended to tempreture, in a way that high temp cause increase in pistilate length and result in cross polination. about eggplant is reported too.
Plant Castor:
1. Pistillate: A flower that lacks stamens is pistillate
2. See attached paper #1: "In the last three decades, India has made significant progress in the development of hybrids. The availability of pistilate lines, like the VP-1, was the base for launching hybrids such as GAUCH-1, GCH-2, and GCH-4 during 1990s and ten more high yielding hybrids later on."
3. Also, a paper (Development of Pistillate Castor) from this link: [ http://www.indianjournals.com/ijor.aspx?target=ijor:ijgpb&volume=33&issue=3&article=023 ]
"Temperatures of 31–32° C promote interspersed male flowers while lower order temperatures result in fully female racemes."
Caster is the crop where temperature dependent pistillate lines are being used for hybrid seed production. But in Rice temperature dependent male sterility can be encountered but not the reversion of hormophodite flower to pistillate condition. In India only caster hybrids are produced ex: GAUCH
