Bisexual flower ontogeny after chemical induction and berry characteristics evaluation in male Vitis amurensis Rupr
چکیده انگلیسی


- Sex expression in male flowers of Amur grape appears to be sensitive to exogenous, applications of CPPU.
- Pistil development of male flowers was arrested before 4-nucleate embryo sac.
- CPPU accelerated pistil development of male flowers, and finally induced octonucleate maturing embryo sac.
- Difference of berry characteristics in different male Amur grape lines was significant.

The sex of the male Vitis amurensis Rupr (Amur grape) flower can be converted to a hermaphrodite form after treatment with N1-(2-chloro-4-pyridyl)-N3-phenylurea (CPPU). This paper describes the results of flower development studies using histological approaches, and evaluates the pollen germination and berry characteristics. In wild-type male grapes, pistil development was arrested prior to the formation of the four-nucleate embryo sac, and the pistil subsequently degenerated. In contrast, CPPU accelerated pistil development, and induced octonucleate embryo sac maturation. Stamen development of CPPU-treated males was similar to control, but pollen germination was lower than control. Also, berry characteristics differed significantly in various male Amur grape lines. Results showed that sex expression of the male V. amurensis Rupr appeared to be sensitive to CPPU that stimulated pistil development to the same extent in hermaphroditic flowers. These data may provide additional germplasm information for evaluation of the male Amur grape, and our data may influence future breeding programs and drive molecular mechanism-based studies of plant sex determination.
