Solanum lycopersicum L. var. cerasiforme, Phloem mobility, Potassium


Boron (B) retranslocation may confer greater tolerance to B deficiency or toxicity, resulting in plants and fruits with better nutritional quality. Most plants do not demonstrate phloem mobility for B; however, some plants have natural mobility and others express it under stress conditions, such as nutritional stress. Therefore, we investigated the phloem mobility of B in cherry tomato plants with different nutritional status. The plants were cultivated in nutrient solution with adequate and insufficient doses of Potassium (K) and B. Furthermore, the plants received foliar fertilization with B in a mature leaf (F) in a localized form. The B content and amount in leaves near F were compared with leaves of the same age and position on control plants. The experiment was carried out in a protected environment and conducted in a randomized complete block design in a subdivided plot scheme with four replicates. Re-translocation of B between neighboring leaves was observed when the plant was without K deficiency and with B deficiency. In this nutritional status, leaves next to fertilized leaf with B (F) showed higher B amount when compared to leaves of the same position of control plants. Evidence suggests that retranslocation of B over relatively short distances (between leaves) can be influenced by the nutritional status the cherry tomato plants.
