Vijaysankar ji Perhaps this paper should be useful in your inquest: http://aob.oxfordjournals.org/cgi/content/full/92/5/715
Here is the portion that I found relevant: "Several factors may be responsible for the low fruit set *in* *B. monosperma* under open-poll*in*ation. Obviously, limitation*of* compatible pollen is one factor. However, even *in* manual cross-poll*in*ations, fruit set was only *in*creased to 23ยท32 %,*in*dicat*in*g that there are additional constra*in*ts for fruit set which have not been *in*vestigated. Although there are four or five *ovules* *in* each ovary *of* *B. monosperma *, only one ovule, usually the one located closest to the style, develops * in*to the seed. *In* *Dalbergia sissoo* (Mohan Raju* et al*., 1996<http://aob.oxfordjournals.org/cgi/content/full/92/5/715#MCG193C30>) and *Syzigium cumini*(Krishnamurthy* et al*., 1997<http://aob.oxfordjournals.org/cgi/content/full/92/5/715#MCG193C23> ), *in* which a s*in*gle seed is predom*in*antly formed, abortion *of* other seeds has been reported to be caused by the production *of* a chemical *of* *in*dole nature, such as 4-chloro*in*doleacetic acid. This aspect has not been *in*vestigated *in* *B. monosperma*." -- Dr. Gurcharan Singh Retired Associate Professor SGTB Khalsa College, University of Delhi, Delhi-110007 Res: 932 Anand Kunj, Vikas Puri, New Delhi-110018.
