two experiments were performed for in vitro establishment, proliferation and shoot growth in axillary bud explants of sebri pear cultivar. in the first experiment, the effect of different concentrations of iba(indole-3-butyric acid) on explants’ establishment was evaluated. in a second experiment, the influence of several combinations of pgrs (plant growth regulators)on shoot proliferation and ...

Plant propagation originated  from the mature tissues is the most desirable method in producing clonal plants, however microbial contamination usually is the main concern during regeneration processes. Moreover, commercial production of plants using clonal propagation is considered as high throughput method due to the   removal of seasonal barriers, lower cost of production with higher yield wh...

Many plant species combine sexual and clonal reproduction. Clonal propagation has ecological costs mainly related to inbreeding depression and pollen discounting; at the same time, species able to reproduce clonally have ecological and evolutionary advantages being able to persist when conditions are not favorable for sexual reproduction. The presence of clonality has profound consequences on t...

A reciprocal transplant-replant experiment was carried out to investigate the clonal plasticity and local specialization of OAFE population (O type) and BF population (U type) of a clonal rhizome herb Iris japonica in contrasting reciprocal heterogeneous habitats on Jinyun Mountain. U Population had better performance of plant size and clonal propagation (including allocation to clonal propagat...

Introduction Koa (Acacia koa) is currently the most important commercialized hardwood in Hawai'r's forests. A sustainable supply of koa will depend on reforestation with the best adapted seed sources and perhaps with vegetatively propagated cultivars having unique traits. At present, koa forests are in a serious state of decline, and improvement appears warranted if sustainable supply is to be ...

using apple clonal rootstocks is necessary for improving crop efficiency in apple orchards. after graftingof apple cultivars on malling rootstocks, the extra parts of the rootstock was used as stem cuttings. apical,middle and basal parts of these shoots were used as cuttings. two propagation conditions, greenhouse andnursery and three concentrations of indole-3- butyric acid (iba) on rooting, c...

Flowering plants possess an unrivaled diversity of mechanisms for achieving sexual and asexual reproduction, often simultaneously. The commonest type of asexual reproduction is clonal growth (vegetative propagation) in which parental genotypes (genets) produce vegetative modules (ramets) that are capable of independent growth, reproduction, and often dispersal. Clonal growth leads to an expansi...
