| dc.description.abstract | Mango fruiting is impacted by flowering and fruit set under unfavourable environmental conditions. Flowering is reported to be controlled by Carbon:Nitrogen ratio, more specifically by their individual concentration and the ratio is regulated by other factors such as hormones, minerals, amino acids, photosynthetic rate and also genotype. In this study, an attempt was made to understand the genotypic differences in flowering and its regulation. Genotypes differing in flowering were selected for the study. In addition to the genotypic differences, carbon accumulation variation was created using girdling and defoliation treatments. A total of 6 varieties, Alphonso, Langra, Dashehari from irregular and Amrapalli, Arka Anmol, Totapuri from regular bearing type were selected for the study. Number of vegetive and reproductive shoots were counted at frequent intervals. C and N content was analysed using CHNS analyser and other metabolites like sugars, amino acids, and hormones were estimated using LCMS. Higher Carbon content, more number of leaves, sucrose, fructose, ABA, SA, IAA, JA acted as positive regulators of flowering by generating more of generative shoots whereas the absence of leaves, GA3 were found to be negative controllers of flowering promoting vegetative shoot growth. Girdling has also influenced the accumulation of compounds and different leaf treatments altered the reserve storage by accumulating more Carbon. Study clearly indicated that the total carbon content rather than the C: N ratio plays an important role in induction of flowers which is influenced further by the flowering signals synthesised in the leaves. | en_US |
