    Effect of Some Quince Rootstocks on Inflorescence Properties, Flowering and Fruit Set in Loquat (Eriobotrya japonica Lindl.)
    (Kahramanmaras Sutcu Imam Univ Rektorlugu, 2022) Akkus, Sibel; Polat, Atila Aytekin
    The present investigation was conducted to determine the effect of different quince clone rootstocks on phenological characteristics, flowering and fruit set ratios of Hafif Cukurgobek (HCG) loquat variety. 'HCG' variety budded on Quince-A, Quince-C and BA-29 rootstocks were planted at 1.0 m x 0.5 m inter and intra-row spacing, respectively, was used for the study. The experiment was arranged as a completely randomized design with 5 replications and 6 plants were used in each replicate. The effects of the quince rootstocks on phenological observations such as the flowering periods and the inflorescence characteristics were recorded. The HCG cultivar which are grafted on all three rootstocks completed the flowering between 11 December and 31 January. The first flowering and fruit set were recorded at the earliest in BA-29, and the latest in Quince-C. Fruit ripening was occurred at the earliest in BA-29 rootstock (May 11), followed by Quince-C (May 18) and Quince-A (May 19). The effect of rootstocks on the number of flower buds and flowers in the cluster, and the number of final fruit set were found significant. In terms of all three features, higher values were obtained in Quince-C rootstock. Quince-A rootstock yielded the lowest value in the ratio of fruit harvested in both years, Quince-C and BA-29 gave close values to each other. As a result, BA-29 and Quince C rootstocks performed better than Quince-A rootstock.
