Tolerance of hybrids between Citrus x aurantium L. x Citrus trifoliata L.

Hybrids between Citrus x aurantium L. x Citrus trifoliata L.

The tolerance of these hybrids is manifested in their ability to maintain viability at low temperatures, resistance to viruses, including Huanglongbing, and adaptation to various soil types.

In the reference 15 varieties crop Hybrids between Citrus x aurantium L. x Citrus trifoliata L., where this is mentioned in the description.

Cold hardiness is a key breeding trait inherited from Poncirus trifoliata. The hybrids are capable of withstanding sub-zero temperatures without critical tissue damage, making them suitable for use as rootstocks in regions at risk of frost.

Tolerance to diseases such as Huanglongbing is expressed by the absence of pronounced disease symptoms, such as chlorosis or growth inhibition, even when the pathogen is actually present in plant tissues. The effectiveness of the hybrids is assessed by comparing the degree of infection with susceptible varieties.

Adaptation to soil conditions is determined by the ability of the root system to maintain functionality in specific soil profiles where pure species show signs of stress. Quantitative indicators of tolerance in this group are not standardized and are determined empirically through field observations.
