Abstract

This research investigates two pear varieties, Olive de Serr and Zimnyaya Nashvati, grafted to several rootstocks and reports their potential interactions, which is a significant missing piece of information regarding which combinations would provide the highest reliability of bud take and seedling performance in local conditions. Using standard horticultural practices, field experiments were performed to evaluate the bud survival and seedling growth and the overall compatibility of four rootstocks (control) Khan Nashvati, Almurt, Yurt Nashvati and Quince A at the Karakalpak Scientific Experimental Station. Results demonstrate that compatibility is highly rootstock dependent. Among the rootstocks, Almurt outperformed the others with the highest bud take rate of 83.1%, which is 8.2% above the control. On the other hand, the weakest compatibility was demonstrated by Yurt Nashvati with bud take of only 61.9% in Zimnyaya Nashvati. Higher establishment rates and increased growth of seeds from Almurt were also confirmed by seedling measurements, further elucidating the Almurt advantage. These findings emphasize the potential benefits of using the most appropriate rootstocks in high density pear orchards. Almurt is a potential rootstock for regions with similar environmental conditions, providing more consistent graft success and better seedling growth. This destructively supported simplistically, high-quality pear orchard systems.
