Special Issue Information

Dear Colleagues,

Breeding forest species can be a costly and slow process because of the large area required for field trials and the long time required to measure economically and environmentally relevant phenotypes. Directional cultivation of seedlings is an inevitable trend and particularly important, as directional cultivation technology can make the tree morphology and physiological characteristics as far as possible in line with the actual situation of a forest, and greatly improve the survival rate of an artificial forest. This Special Issue aims to explore better targeted breeding techniques and advanced forestry management practices for tree breeding. We invite forestry researchers to discuss the suitable seedling cultivation methods and techniques and the rapid propagation method of selecting individuals for different forest species to cultivate high quality seedling and lay the foundation for forest construction. In this issue, studies on forestry breeding, directed cultivation technologies and forest tree cultivation management measures are warmly welcomed. The directional cultivation technology is not mature at present, so papers submitted in this Special Issue are expected to emphatically discuss the advanced technical strategy and key points of directional cultivation.

Populus ussuriensis is an important tree species with high economic and ecologic values. However, traditional sexual propagation is time-consuming and inefficient, challenging afforestation and wood production using P. ussuriensis, and requires a rapid and efficient regeneration system. The present study established a rapid, efficient, and stable shoot regeneration method from root explants in P. ussuriensis using several plant growth regulators. Most shoot buds (15.2 per explant) were induced at high efficiency under WPM medium supplemented with 221.98 μM 6-BA, 147.61 μM IBA, and 4.54 μM TDZ within two weeks. The shoot buds were further multiplicated and elongated under WPM medium supplemented with 221.98 μM 6-BA, 147.61 μM IBA, and 57.74 μM GA3 for four weeks. The average number and efficiency of elongation of multiplication and elongation for induced shoot buds were 75.2 and 78%, respectively. All the shoots were rooted within a week and none of them showed abnormality in rooting. The time spent for the entire regeneration of this direct shoot organogenesis was seven weeks, much shorter than conventional indirect organogenesis with the callus induction phase, and no abnormal growth was observed. This novel regeneration system will not only promote the massive propagation, but also accelerate the genetic engineering studies for trait improvement of P. ussuriensis species. Full article
