Physiological Aspects of Compatibility and Incompatibility in Grafted Cucumber Seedlings

The use of grafted seedlings in vegetable crops has increased in recent years to enhance the resistance to biological and abiotic stresses, and improve yields. However, incompatibility restricts the wide application of grafting. In this study, two pumpkin (Cucurbita) cultivars, with great differences in grafting affinity and symbiotic affinity, were used as rootstocks and cucumber (Cucumis sativus) seedlings were used as the scion. The effects of compatibility or incompatibility on histological aspects, antioxidant enzyme activities, phenylpropanoid contents, and chlorophyll fluorescence were studied. The results showed that compatible graft combinations present a stronger resistance to the oxidative damage resulting from grafting and had relatively weak phenylpropanoid metabolisms. The results also indicated that the chlorophyll fluorescence levels of incompatible combinations were lower, except compared with the original fluorescence. Finally, a necrotic layer existed earlier in compatible graft combinations. These differences at the morphological, physiological, and cellular levels may govern compatibility and incompatibility, and may provide valuable information for determining the symbiotic affinity of grafted seedlings at an early stage.

GH and IGF-I concentrations decline with age. Age-related changes appear to be linked to decreases in the anabolic hormones, GH and IGF-I. The aim of this study was to investigate the antioxidant, anabolic, and metabolic effects of the IGF-I replacement therapy, at low doses, in aging rats. Three experimental groups were included in this protocol: young healthy controls (17 wk old); untreated old (O) rats (103 wk old); and aging rats (103 wk old) treated with IGF-I during 1 month (2.25 μg IGF-I/100 g body weight−1·d−1). Compared with young controls, untreated aging rats showed a reduction of IGF-I and testosterone levels, and a decrease of serum total antioxidant status, which were corrected by IGF-I therapy. In addition, untreated O presented increased levels of serum glucose with hyperinsulinemia, cholesterol, and triglycerides, and a reduction of free fatty acid concentrations. IGF-I therapy was able to revert insulin resistance, and to reduce cholesterol and triglycerides levels increasing significantly free fatty acid concentrations. The O group showed higher oxidative damage in brain and liver tissues associated with alterations in antioxidant enzyme activities. IGF-I therapy reduced oxidative damage in brain and liver, normalizing antioxidant enzyme activities and mitochondrial dysfunction. In conclusion, low doses of IGF-I restore circulating IGF-I, improve glucose and lipid metabolism, increase testosterone levels and serum total antioxidant capability, and reduce oxidative damage in brain and liver associated with a normalization of antioxidant enzyme activities and mitochondrial function.
