6. Importance
•Increased production under adverse environment
•Seedless fruits
•Improved quality
•Protected cultivation
•Reduced cost of cultivation
(Varoquaux et al., 2002)
3 December 2017 HC & RI, PKM 6
7. Causes for absence of pollination
•Male sterility
•Self incompatibility (Wheeler et al., 2001)
•Adverse environmental condition (Krug, 1997)
•Absence of pollinator and pollinizer
•Dioecious
7HC & RI, PKM3 December 2017
8. Mechanism of parthenocarpy
•Seed and fruit development control by phytohormones.
(Pandolfini, 2009)
•GA3, Auxin and Cytokinin involve signaling process after
fertilization for seed and fruit development.
(Fos et al., 2001)
•Increase endogenous hormones during parthenocarpic fruit set not
from source of seed.
(Tsao, 1980)
•Trigger the expression of auxin biosynthetic gene
(Carmi et al., 2003)
8HC & RI, PKM3 December 2017
9. Nature or genetic parthenocarpy
•Obligatory (genetic)
Parthenocarpic trait not influenced by external factors
eg. Ivy gourd
•Facultative
Adverse environmental condition
eg. Tomato, Brinjal
(Nitch, 1970; Gillaspy et al., 1993)

10. Genetics of parthenocarpy
•Heritable in nature
•Tomato - Several single gene recessive (Fos et al., 2001)
•Eggplant - Single dominant gene (Kuno and yabe 2005)
•Capsicum - Single recessive gene (Tiwari et al., 2011)
•Cucumber - Additive - dominant epistatic gene and additive
- dominant polygenes (Yan et al., 2010)

Intra specific hybridization

GA3 was the most
active followed by GA1 and GA4 (equally active), and
GA20. Interestingly, GA19 (the immediate metabolic
precursor of GA20) was completely inactive (Fig. 2).
These results suggested that GA 20-oxidase activity is
limiting in unpollinated ovaries.
