Citrus rootstocks differ in compatibility to kinds of soils, manner of root dispersion and affiliation to micorhyza. This object lead to difference in leaf mineral elements concentration or leaf of budded cultivars on them and finally affect vegetative growth and fruit quantity and quality. In a budded tree, rootstock type affects many scion properties such as plant height, plant spread and Plant volume. Highest Number of fruits per plant, number of kg per plant as well as Fruit quality like highest juice percentage, TSS, Acidity and Ascorbic acid observed in Valencia late. Valencia orange is the most important late ripening sweet orange in the world, which has good compatibility with warm region. This cultivar is commercial and its fruit has good marketable and fruit permanency on tree is excellent. Somewhat is resistant to cold and drought and in due to proper compatibility. Attentive to budding propagation and using of different rootstocks for this cultivar and non-existence of sufficient information on interaction between it and rootstock type, aim of this investigation was the effect of rootstock type on Growth and International Journal of Current Microbiology and Applied Sciences ISSN: 2319-7706 Volume 7 Number 04 (2018) Journal homepage: http://www.ijcmas.com Effect of citrus rootstock Rough lemon (C. limon Linn. Burn Citrus jemberi) on plant growth and fruit quality of sweet orange varieties like Pera, Pine apple, Jaffa, Washington novel, Hamlin, Valencia late, Sathgudi and Blood red malta evaluated at All India Coordinated Research Project on Tropical Fruits (Citrus), Dr. Panjabrao Deshmukh Krishi Vidyapeeth, Akola 2012-13. Budded Valencia late orange on rootstock were grown in medium, well drained and maintained free from weeds. The physical and chemical properties of soil are as suitable. Results showed that rootstock had significant effect on growth and development as well as Fruit quality of Valencia late. Highest Plant height (4.42m), Plant mean spread (4.17m) and Plant volume (40.31m 3 ) on Rough lemon rootstock. Rootstock types had significant effect on highest Number of fruits per plant (232.76), number of kg per plant (32.75) as well as Fruit quality like highest juice percentage (53.15), TSS (12.56 brix), Acidity (1.01%) and Ascorbic acid (57.86 mg/100 ml juice) were budded on rough lemon rootstock.
