The effect of nitrogen on the growth of stock plant and subsequent rooting of cuttings of aquilaria microcarpa baill
Aquilaria sp. has high economic value but the shortage of seedling, poor seed germination and overexploitation has threatened the population.

description |
Aquilaria sp. has high economic value but the shortage of seedling, poor seed germination and overexploitation
has threatened the population. A study on the growth performance of A. fI1icrocatpa Baill. stock plants under
different nitrogen (N) level (0 mg/L, 50 mg/L, 100 mg/L, ISO mg/L and 300 mglL) treatment and the
subsequently rooting response of cuttings was conducted. Ammonium nitrate, NH4N03 was used as the N source.
The treatment with 100 mglL of N showed the best result where the increment mean value of plant height, stem
diameter and number of leaves was 20.64 em, 1.81 mm and 19 leaves, respectively. The poor increment was
resulted in the control group (0 mg/L N), which was 0.94 cm, 0.65 mm and a decreased of I in the leaves number.
50 mglL N was also considered as a good treatment because the growth performance of stock plants were not
significantly difference from those treated with higher N concentration. All the stock plants treated with N
yielded sufficient healthy cuttings materials. Overall, the mortality rate of cuttings was high (32%) due to over
misting. About 13% of the cuttings were rooted. Stock plant treated with 50 mg/L N proved to be good for the
rooting of cuttings. No significant difference resulted in the rooting response of cuttings between hormone
treatments. In terms of rooting performance, "Seradix I" gave the highest result in the number of visible roots
and total root length compared with those without hormone or treated with "K-IBA". |
