Abstract:

The aim of the study is to illuminate the possibilities of using of hawthorn (Crataegus spp) as rootstock in loquat (Eriobotrya japonica Lindl.) growing. For this aim, cv. Hafif Çukurgöbek (HÇG) was budded on the hawthorn rootstocks on 8th February, 18th May, 7th August, and 31st October 2019 with the chip budding method in the field conditions. The percent of bud-take successes were recorded after 45 days of the budding operations. In the bud-take, the top of the rootstock was cut from 10 cm above the budding point in order to sprout of the budding. After 15 days from this cutting, the ratio of bud-sprout was recorded. In addition, the bud shoot length and bud shoot diameter and also rootstock trunk diameter in all plants except dormant buddings were assigned in two different times on 24 December, 2019 and 8 February, 2020. The trial was planned in a completely randomized design with 6 replications and 10 plants per replication. Differences among means were analyzed by the Tukey's HSD method using SAS program. The highest values of bud take (47.6 %) and sprouting (70 %) rates were taken from budding done on 7th August, 2019. This was followed by 31st October, 2019 with 41.67 % bud take and bud sprout (% 21.43). The lowest budding success rate (10.58 %) was taken from the buddings which were done on 8th February, 2019. In both periods of measurement, budding done on 18th May 2019 yielded the higher values of bud shoot length and diameter. Preliminary results of this study show that hawthorn rootstock can be used in loquat cultivation.
