The effect of spermidine from two biosynthetic paths on flowering of early and late flowering genotypes of eggplant Solanum melongena L Zahra rezaeyan z rezaeyan@ag iut ac ir July 2 2019 Department of Horticultural Science Isfahan University of Technology Isfahan 84156 83111 Iran Degree M Sc Language Farsi 1st Supervisor M Haghighi mhaghighi@cc iut ac ir 2nd Supervisor M Mobli mmobli@cc iut ac irAbstractEggplant is a Hemafrodite plant from the Solanaceae family and has heterostyle phenomenon flowering with differentstyle lengths in flowers The flowers appear in three forms of high style medium style and short style and about22 30 of the flowers of the eggplant make up short style flowers Flower morphology and style length are one of thefactors limiting the pollination fertility and fruit formation in eggplant Studies confirms the role of hormones inimprovement of the flowers heterostyley in eggplants Research has shown that polyamines includingspermidine spermine and putresin play a role as plant growth regulators in processes such as flowering growth anddevelopment of the reproductive organs the formation growth and ripening of fruits This research was carried out toinvestigate the effect of spermidine and its synthesis routes on flowering and fruit formation in two early and lateflowering genotypes of eggplant during two experiments in a completely randomized and semi experimental factorialdesign in greenhouse of Isfahan University of Technology The first experiment consisted of genotype factor twoearly and late flowering genotypes and chemicals 1 mM spermidine 0 5 mM spermidine two compounds inhibitingthe spermidine synthesis route and control in order to investigate the effect of external spermidine on flowering andfruit formation In the second experiment two first experiment genotypes and treatments consisted of twoconcentrations of one and a half milimolar spermidine three inhibitory treatments with a concentration of 3 mM andmethionine amino acid at a concentration of 200 mg L and control treatment distilled water to study the floweringmechanism in two early and late flowering genotypes of eggplant was taken Treatments were applied in three stagesof vegetative growth beginning of flowering and 10 days after flowering Spermidine increased the traits such asplant length number of lateral branches length of style percentage of high style flowers percentage of fruitcomposition and yield The highest plant height was observed in 0 5 spermidine treatments in both cultivars and thelowest in the combination of two inhibitors of early flowering genotypes Also the highest number of days toflowering was observed in the combination treatment of two inhibitors of late flowering genotype and its lowest inspermidine treatment of 0 5 early flowering genotypes The highest fruit weight and yield were related to 1 mMspermidine treatment and the late genotype and the least of them was observed in the combination treatment of twoinhibitors in the early genotypes The result of this study was that spermidine was an effective treatment for theimprovement of flowering and fruit characteristics in two genotypes The results of the second experiment indicatedthat in the late flowering genotype the blocking of the methionine precursor path had more inhibitory effects onreproductive and fruiting characteristics and it could be said that the pathway was more active in flowering andfruiting of this genotype In early flowering genotype flowering traits such as the late flowering genotype acted on but in the case of the traits of fruit the effect of spemidine has been shown to be lower in the genotype and perhapsthe pathway is more active in this regard Finally based on the results it can be argued that the activity of syntheticpathways and their effects on different processes depends on the different cultivars and stages of the development ofthe eggplant Keywords Eggplant heterostyly polyamine syntesis inhibitors 76
