Chilling damage in citrus depends on several factors. …
By Manjul Dutt, Ethan Nielsen, Lamiaa Mahmoud, Maria Quirico and Jude Grosser All commercially cultivated citrus scion varieties are grafted onto rootstocks before being planted in the field. The rootstocks are selected based on specific desirable qualities (abiotic/biotic stress resistance) and the ability to produce a good crop in a specific location. The ideal rootstock confers disease resistance, hardiness, tolerance …
