Abstract Background: The mechanisms by which nitrogen (N) affects the allometric growth of plant organs by influencing the distribution of different hormones in plant organs remain unclear. Therefore, this study aimed to examine the effect of soil N levels on soil properties, the hormonal activities and growth parameters of Pinus tabuliformis Carr. Methods: Seedlings of P. tabuliformis were subjected to 0, 3, 6, 12 g of N m-2 year-1. Growth parameter and hormone activity data (trans-zeatin riboside (ZR), gibberellin (GA1+3), indole acetic acid (IAA), abscisic acid (ABA)) in leaf, stem, total root, coarse root (diameters >2 mm), fine root (1-2 mm) and finest root (0-1 mm) biomass were measured and analysed. Results: The results showed that N addition increased the growth of the leaves; stems; total roots; and coarse, fine, and finest roots of the seedlings, but decreased the ratio of underground to aboveground growth. Additionally, N addition increased the ZR content in stems, while decreasing the ABA content in leaves and whole roots and the GA1+3 content in whole roots, but IAA content was not significantly influenced by N addition. Furthermore, the hormones examined significantly influenced the growth of the leaves, stems, roots, and the coarse, fine, and finest roots. Conclusions: N addition affected the trans-zeatin riboside, gibberellin, indole acetic acid, and abscisic acid content in the various organs examined, which influenced the growth of the seedlings. Our research will provide an important reference for forestland governance and forest systems management under global atmospheric N deposition.

A pot experiment was conducted in the rabi (post rainy) seasons of 2001 and 2002 to study the genotypic differences in grain growth rate and endogenous hormonal content in the developing grains of hexaploid and tetraploid wheat. The endogenous hormonal contents of grains in both the ploidy levels had changed in sequence. At 5 days after anthesis (DAA), gibberellic acid (GA3); at 15 DAA (rapid growth phase), indole-acetic acid (IAA); at 25 DAA (dough stage), abscisic acid (ABA) were maximum. At 35 DAA, all the endogenous hormonal level decreased and among the hormones, ABA was highest followed by IAA and GA3. Hexaploids recorded higher concentrations of endogenous hormones (13.38% IAA, 17.89% GA3, and 14.7% ABA) on fresh weight basis and resulted in higher seed weight (56.99 mg/grain) and grain growth rate (0.009 g/g/day) compared to tetraploids (49.08 mg/grain; 0.008 g/g/day) on dry weight basis by better mobilization of photosynthates during grain filling. Key Words: Grain growth rate, hormones, indole-acetic acid, gibberellic acid, abscisic acid. doi:10.3329/bjar.v33i3.1608 Bangladesh J. Agril. Res. 33(3) : 493-502, September 2008
