“…Defoliation causes a lack of supply of carbohydrate and fruit removal involves the loss of a major carbohydrate sink and accumulation of carbohydrate in roots (Okuda et al, 2002;Shimizu et al, 1978). Girdling causes accumulation of carbohydrate within the girdled branch (Goldschmidt et al, 1985).…”

In the citrus industry, juvenility and alternate bearing are serious problems that cause lengthening of the breeding cycle and instability of annual fruit production, respectively. Both phenomena are closely related to flowering behavior: juvenility is caused by suppression of flowering in young plants and alternate bearing mainly results from suppression of flowering by fruit production. Many researchers have conducted studies into citrus flowering in a quest to resolve these problems. In recent years, molecular and genetic approaches to studying citrus flowering have been performed on the basis of studies on flowering-related genes in Arabidopsis. In Arabidopsis, the protein encoding a flowering-related gene, FLOWERING LOCUS T (FT), plays an important role in the promotion of flowering. Similarly, a citrus orthologue of FT (CiFT) has been confirmed to have a function in the promotion of flowering in citrus. In studies of transgenic plants, a CiFT co-expression vector has been already used to shorten the juvenile phase of citrus. In addition, endogenous expression of CiFT is closely correlated with flowering under various conditions, suggesting that endogenous CiFT may regulate floral induction. Considering the accumulating data, the regulation of CiFT expression is hypothesized to be essential to understand the mechanism of citrus flowering and studies on CiFT are expected to contribute to the resolution of flowering-related problems in citrus.

“…The starch content of roots decreased immediately after the commencement of the 10-flood and 30-flood treatments in both grafted trees and seedlings, whereas there was no clear difference in sugar content among the treatments. The starch content in satsuma mandarin roots, a subtropical evergreen fruit tree, is generally low during the growing season and tends to increase during the dormant season [16]. Since this experiment was conducted during the growing season in summer, the starch content of 40-70 mg g −1 DW in the grafted trees and seedlings before the commencement of treatment was considered to be the lowest level of the year.…”

The risk of flooding has increased as a result of climate change inspired by global warming. In this study, the difference in tolerance to flooding between grafted trees and seedlings was investigated in mango trees (Mangifera indica L.). Two levels of flooding treatment were established, in addition to a non-treated control. One was “30-flood,” in which trees were submerged up to 30 cm from the soil surface, and another was “10-flood,” in which trees were submerged up to 10 cm from the soil surface. Grafted trees treated with the 30-flood were submerged up to 5 cm above the graft union. Only the grafted trees in the 30-flood treatment began to decrease Fv/Fm and the root sugar content during treatment, then died after the completion of treatment. In grafted trees and seedlings alike, both flooding treatments also reduced root vigor, as determined by triphenyl tetrazolium chloride reduction tests and root starch content. However, root vigor and root starch content in grafted trees treated with the 10-flood as well as seedlings treated with both 10- and 30-flood recovered within two months after the completion of treatment, so that no significant differences were detected between the control. These results suggest that the submergence of the graft union into water causes the decline in photosynthesis of the scion first and the death of the grafted trees as a result.
