Abstract:

In order to explore the relationship between the nutrient distribution of leaves and flowers during the development of Anthurium, Alabama was used as the test material to measure the morphological characteristics, net photosynthetic rate and trehalose-6-phosphate synthase (TPS) activity of leaves at different developmental stages. The development status of flower buds was recorded after the sucrose solution treatment. The results showed that for the same growing tip, one leaf corresponded to one bract. T1-T3 stage focused on the leaf development. The corresponding bract was mainly developed in T3-T5 period. Leaf area and petiole elongation gradually stopped and it provided nutrients to bract and made them develop rapidly at T3-T5 stage. The activity of TPS in bracts was higher than that in leaves at T1, T4 and T5, but there was no significant difference between bracts and leaves at T2 and T3. The appearance rates of flower buds were increased under sucrose solution treatment with mass fraction of 15‰, 20‰ and 25‰, respectively. In conclusion, the characteristics of one leaf corresponding to one flower make the flower and leaf have different nutritional competition relationship in different periods, and sucrose plays an important role in the development of Anthurium flower.
