摘 要：Trees have a long juvenile phase before reproductive *** makes their breeding and studying floral development *** flowering using FT technology has shown ***,transgenic FT overexpression has significant negative pleiotropic ***,there has been interest in inducible FT expression for flower *** reported heat inducible expression of FT in poplar successfully induced ***,flowering was sporadic and took up to 6 *** we report improvements in the protocol,which led to faster and more prolific ***,we increased the once to three times daily heat *** repeated heat inductive treatments led to nearly five times higher FT expression,compared to the single daily *** highly increased FT expression led to significant acceleration and abundance of flowering.
