Influence of rootstocks on vegetative growth of Kinnow mandarin scion under rainfed areas

Abstract

The study was installed at Rainfed Research Sub-station for Sub-tropical Fruits, Raya, SKUAST-Jammu to better understand and elucidate the effect of citrus rootstocks on vegetative growth of Kinnow mandarin cultivar in the pre-bearing stage. The experiment design was RBD randomized design in research farm under rainfed condition with four replications. The magnitude of scion growth revealed stimulated increase in percentage in rainy season between July–October compared to November–February in winter seasons under rainfed condition. The plant growth of Kinnow mandarin on Jatti khatti rootstock was better in terms of per cent increase in plant height (39.50%) in rainy and (18.60%) was register in winter season. Whereas the maximum plant spread [N-S (60.70) and E-W (59.56)] in rainy and [N-S (29.56) and E-W (27.20)] percentage increase in winter season was recorded on galgal rootstock. Results showed that an influence different type of rootstock has effect on evaluate scion and root diameter ration in kinnow mandarin budded plants. Maximum increment in scion (64.53%) and root diameter (60.36%) was recorded in jatti khatti and rough lemon budded rootstock plants. Whereas the lowest vegetative growth of scion (19.85%) and root diameter (18.85%) in rainy and (1.29%) and (1.12%) in the winter was observed in on carrizo citrange rootstock.
