When poplars were introduced in Pakistan about a decade back, emphasis was placed on only one clone viz. P. euramericana CV-I-214 due to its intrinsic qualities of almost cent per cent rooting and fast rate of growth. Subsequently, some deltoides clones were also imported which showed comparatively better rate of growth but low rooting capability, prohibiting their large scale planting. Experiments were under� taken both with c...
