An experiment was laid out to study the impact of eCO2 (550ppm), eT ( + 3ºC) and their interaction
(eCO2 + eT) on rooting behaviour of cuttings of three grape varieties- Thompson Seedless, Bangalore Blue,
and Dogridge in FATE and OTC facilities. Observations were recorded at 50 and 80 days after planting
(DAP) and root growth data was recorded and analysed using WinRHIZO root scanner and its software.
Analysis revealed that, among the selected grape varieties, Thompson Seedless cuttings has shown highest
number of roots, root volume and dry biomass under eCO2 and eCO2 + eT conditions, while total root length
and root length density were highest with Bangalore Blue. Under eT condition, Bangalore Blue showed
highest number of roots, total root length and root length density, while root volume and dry biomass was
highest with Thompson Seedless. The per se values of root parameters under all conditions and their
response to eCO2 was lowest with Dogridge. Though eT condition reduced all the root parameters, their
performance improved under eCO2 + eT indicating the presence of higher concentration of CO2 reduced the
ill effects of high temperature. Overall, eCO2 and eCO2 + eT conditions improved root parameters of grape
varieties, while eT reduced them as compared to their performance under ambient condition and varietal
variation is significant
