Abstract:
Nucellar seedlings of mango cv. Vellaikolamban were dwarfing when used as a rootstock for cv. Alphonso scions, while those of cvs Muvandan, Bappakai and Olour behaved as vigorous rootstocks, in decreasing order. There was more flowering, and less vegetative flushing when ‘Alphonso’ was grown on this dwarfing rootstock. An inverse relationship between the phenolic content of stem apical buds of the scion and tree size was observed. Differences in leaf nutrient status of ‘Alphonso’ on the various rootstocks were significant for N, K, Fe, Ca, Mn, and Cu, but not for P, Mg and Zn. Vigorous rootstocks led to higher leaf N contents and the least vigorous rootstock resulted in the lowest values of N, K, and Fe. The highest content of the last two nutrients were also recorded on the vigorous rootstocks cvs. Olour and Muvandan. Although fruit yield per tree was high on the yigorous rootstocks and low on cv. Vellaikolamban, productivity, expressed as fruit yield per unit space occupied by canopy, was higher on the latter, indicating the potential of Vellaikolamban as a dwarfing rootstock for high-density orchards. In areas where land availability is not limiting, nucellar seedlings of ‘Olour’ may be better rootstocks when planting ‘Alphonso’ at wider spacings. Zygotic seedlings of ‘Alphonso’ as well as .nucellar seedlings of cvs Chandrakaran, Mylepelian and Kurukkan seemed not to hold promise as rootstocks for ‘Alphonso’. Fruit quality was not affected by any of the rootstocks tested.
