Paulownia Pao Tong Z07, aslo called Super Hybrid, is a cross of 3 species of p. Tomentosa, p. Fortunei and p. Kawakamii. Variety beccomes one of the most popular by all other varieties in industrial production because these qualities:
- rapid growth. Following the studies made was found that trunk diameter reaches 40 cm in 7 years, much faster than other varieties. Rapid growth will reduce harvest time and increase wood production;
- high quality wood, straight, tall and dense trunk;
- cold resistance. The most important factor which made Z07 popular in colder climates where growing of other Paulownia varieties was not possible. It is resistant to extreme hot (up to +40c) and frost (up to -33c);
- resistance to diseases, microbes and parasites;
- easy adaptation to different growing conditions;
- drought resistance after tree is established.
Due to the small crown of the tree, it is possible to plant from 640 to 850 trees per hectare.
