Study on the Morphological Indexes of Hevea brasiliensis under Different Days of P Deficiency Treatment on H.brasiliensis Seedling
[Objective] Study the effects of P deficiency on the morphological indexes of Hevea brasiliensis. [Method] The hydroponic culture experiments were carried out with the clone RRIM600 (H. Brasiliensis) seedling under different days of P deficiency treatment. [ Result ] Under different days of P deficiency treatment, comparing with the normal P (CK) , the P deficiency significantly decreased the plant height, total bi-omass and leaf biomass, but no obvious change occurred in the root biomass, tap root length, stem girth and the biomass. The P deficiency decreased the dry matter partitioning of leaf, but increased the dry matter partitioning of root, meanwhile no obvious changes of dry matter partitioning occurred in the stem. [ Conclusion ] The morphological indexes of H. Brasiliensis have obviously changed under P deficiency treatment.
