Different Doses

The objective of this study was to determine the best vermicompost dose for seedling production of Apuleia leiocarpa. The experiment consisted of five treatments, which were conducted in a greenhouse. The following doses of vermicompost were tested: control (without vermicompost); 10% vermicompost; 20% vermicompost; 30% vermicompost and 40% vermicompost of the total container volume (185 cm3). The experimental design was entirely randomised. The substratum used was bark of Pinus sp., which was triturated and composted. A hundred days after seedling germination, the following variables were analysed: height and diameter growth, above ground dry matter, root dry matter and total dry matter. The 30% vermicompost doses showed to be optimum in growth response and biomass production of Apuleia leiocarpa seedlings.

Fast Growing Species

Deforestation of tropical dry forest reduces soil fertility, with negative effects on future restoration intervention. To evaluate the effect of initial soil properties on three-year performance of six tree species in restoration settings, we measured C, N, and P contents in topsoils of 48 plots under minimal (exclusions of livestock grazing) and maximal (plantings of six native species) restoration intervention during two years in tropical dry forest in central Mexico. Survival and height and diameter relative growth rates were evaluated by species and by growth rank (three fast- and three slow-growing species). After two years, organic C and the C:N ratio increased early during natural succession; these increases might be related to high density of N2-fixing recruits at both intervention levels. Changes in N availability for plants (i.e., NO3− and NH4+ contents) occurred after cattle exclusion. After 40 months, the fast-growing legume Leucaena esculenta (DC.) Benth. had the highest survival (65.55%) and relative growth rate in both height (3.16%) and diameter (5.67%). Fast-growing species had higher survival and diameter growth rates than slow-growing species. Higher diameter growth rates for fast-growing species may be associated with a higher ability to forage for soil resources, whereas similar height growth rates for slow and fast-growing species suggested low competition for light due to slow natural succession at the site. Planted seedlings had higher survival possibly due to initial high NO3− content in the soil. Also, fast-growing species seem to benefit from initially higher pH in the soil. Both soil properties (i.e., pH and NO3−) may be augmented to favor the performance of fast-growing species in restoration plantings and to further accelerate soil recovery in tropical dry forests.

Neolamarkia cadamba (Roxb.) is a fast growing species recognized as a raw material for match wood industry, pulp wood, plywood industry. Seeds from thirty CPTs of Neolamarkia cadamba across the India were collected and evaluated in nursery for various growth and variability parameters. Significant variation was recorded for shoot length, root length, collar diameter, root shoot ratio, biomass production, sturdiness quotient, volume index and quality index among 30 genotypes. FCRIAC 6 (Pantnagar), have outperformed in seven growth parameters studied, followed by FCRIAC 11 (Chandrapur), FCRIAC 19 (Ragihosalli), FCRIAC 20 (Kodigehalli), FCRIAC 26 (Nashik) performing better in six growth parameters. Shoot length, biomass production and volume index registered high genetic estimates. Heritability was high for all the growth characters. PCV values were slightly higher for all the parameters compared to GCV. Collar diameter, shoot length and root length positively and significantly correlated with biomass, volume index, sturdiness quotient and quality index both genotypically and phenotypically. These results will assist in early selection of good performing and fast growing genotype for raising plantations as well as during further investigation in field trials.

Coppice Management

Coppice management is an ecologically important silvicultural practice to provide the quicker and higher potential of wood biomass production for industrial demands. Understanding morphological and anatomical responses of coppiced trees could help to determine the quantity and quality of wood and thus provide better management of coppiced tree plantations for short-time biomass production. However, there is a little investigation in morphological and anatomical adaptation in different fast-growing tree species. The present study, therefore, studied how morphology and anatomy vary between two fast-growing coppices of Populus nigra L. (black poplar) and Salix alba L. (white willow). Each coppiced tree was grown in a similar habitat and was at a similar age. However, each coppiced tree showed different morphological and anatomical plasticity in their stems in response to environmental factors. Poplar coppices showed better anatomical properties due to greater vessel diameter, fibre length, fibre width, fibre wall thickness, and ray height; however willow coppices had better morphological plasticity which had higher average stem height and ring width. The results suggest that willow coppices had the greater height growth potential even at 2 years of age than poplar coppices.
