The aim of the present work was to investigate the acclimation potential of acacia hybrid (Acacia mangium Willd×Acacia auriculiformis A.Cunn.ex Benth)vegetative propagules to soil water stress in the nursery of Institute of Forestry and Environmental Sciences, Chittagong University. Acacia hybrid showed significant decrease in total plant biomass in two months water-stressed conditions. Allocation of assimilates to root growth relative to shoot found to be an important acclimation mechanism. Leaf area ratio (LAR)increased under water-stressed plants with simultaneous increase in specific leaf area (SLA)but almost no change in leaf weight ratio (LWR). Significant increase in LAR with limited water supply by increasing SLA was likely to be an important acclimation potential since this relative increase in leaf area compensated, at least partially, for a lower photosynthesis under water-stressed conditions aswas evident from decreased mean total biomass under water-stressed regimes.

In the last decades, clone testing has become an important component of the long-term breeding and seed orchards for Norway spruce in Sweden. For more than three decades, considerable resources have been spent on testing clones intended for clonal forestry, but the Swedish forestry never saw it worth to pay the added cost involved in the added gain. The efforts, however, resulted in many clone trials and developments in the technique for clone production and propagation. Theoretically, clone testing is faster and cheaper than progeny testing and more reliable than selecting individuals forwards. Nowadays, the main line in long-term breeding is to make crosses between the best trees and test-cloned full-sibs as a recruitment population for long-term breeding and seed orchards. Since controlled crosses are a bottleneck for long-term breeding, a possibility is to rely on wind pollination (Breeding Without Breeding; BWB) in trials for testing clones. The seed parent is known, and that the pollen parent is a desirable genotype can be checked by molecular markers. BWB has the potential to eliminate the waiting time between selection and recombination, which is particularly important in a late and irregularly flowering species such as Norway spruce. Clone testing ensures that the breeding values are known from the same tests as those used for BWB. Another option for BWB is to place in seed orchards a few ramets of clones belonging to the breeding population, but normally not deserving such a use, with the hope that their presence will make it possible to rely on wind pollination to recombine the whole breeding population.
