“…В насадженнях селітебної та магістральної зони енергія проростання та лабораторна схожість насіння складали 24-74 % та 35-61 % відповідно [3]. Схожі показники лабораторної схожості виявлені у насіння у Р. abies, зібраного з не автохтонних рослин біля видобувної фабрики, яке проросло до 83,0 % навіть після 29 років зберігання [27]. Такі показники мають значні розбіжності з отриманими нами даними.…”

Reproductive capability is considered as one of indicators of successful introduction; it helps to evaluate adaptation potential of plants, especially in techogenic conditions. The aim of our work is to research morphometric parameters of cones, profitability and seed quality of Рісеа аbies та P. pungens in the plantations with various levels of aerotechnogenic influence in conditions of an industrial city in the steppe zone of Ukraine. The objects of the studying were the cones of 30–40-year-old trees of P. аbies та P. pungens from eight different plantations situated along the whole city of Kryvyi Rih (126 km) and having various levels of technogenic pollution. We revealed that the maximal length of cone in two investigated species (108,4 and 88,7 mm respectively), width (28,6 and 24,7 mm); the highest seedling vigour (41,0 and 7,2 %), laboratory germination (54,2 and 20,6 %), seed mass (6,9 and 4,2 g), and length of germ (18,5 and 13,8 mm) are noted in the trees from Botanical Garden. The minimal values of all the same indices were ascertained for the trees growing near the metallurgical combine “ArcelorMittal Kryvyi Rih”: length of cones – 92,3 and 73,9 mm; width of cones – 26,2 and 22,4 mm; as well as the lowest seedling vigour (2,4 and 1,4 %); laboratory germination (5,0 and 2,0 %), seed mass (5,4 and 3,4 g), and length of germ (12,6 and 5,4 mm). The general seed quantity for a cone of P. аbies та P. pungens, in all the plantation types, varied from 203,9 to 217,2 seeds and from 198,6 to 204,3 ones respectively. The least part of fertile seeds (11,5–13,3 %), and the biggest part of sterile (56,5–58,7 %) and underdeveloped (29,8–30,1 %) ones were noted in the plants of P. pungens directly exposed to emissions of industrial enterprises; for the plants of P. abies the same indices were 20,2–22,5 %; 51,5–52,6 % та 26,0–27,2 % respectively. Therefore, increasing level of techogenic pollution by air pollutants, which is observed during some last years, oppresses the generative sphere of species of genus Рісеа in conditions of the steppe zone of Ukraine.

“…Storage of germplasm (seeds, dormant buds, meristems, embryos, cells, pollen and DNA) under sub-zero temperatures (0 to 2 808C) and cryopreservation (2 1968C) offers opportunities for conservation of germplasm (Table 1) in forest trees (Sakai, 1986;Ahuja, 1989Ahuja, , 1994Engelmann, 2004;Suszka et al, 2005). Seeds of redwoods have been stored at low temperatures for various lengths of time.…”

This study reviews the various conservation strategies applied to the four redwood species, namely coast redwood (Sequoia sempervirens), Sierra redwood or giant sequoia (Sequoiadendron giganteum), dawn redwood (Metasequoia glyptostroboides) and South American redwood or alerce (Fitzroya cupressoides), which are endemic in the USA, China and South America, respectively. All four redwood genera belong to the family Cupressaceae; they are monospecific, share a number of common phenotypic traits, including red wood, and are threatened in their native ranges due to human activity and a changing climate. Therefore, the management objective should be to conserve representative populations of the native species with as much genetic diversity as possible for their future survival. Those representative populations exhibiting relatively high levels of genetic diversity should be selected for germplasm preservation and monitored during the conservation phase by using molecular markers. In situ and ex situ strategies for the preservation of germplasm of the redwoods are discussed in this study. A holistic in situ gene conservation strategy calls for the regeneration of a large number of diverse redwood genotypes that exhibit adequate levels of neutral and adaptive genetic variability, by generative and vegetative methods for their preservation and maintenance in their endemic locations. At the same time, it would be desirable to conserve the redwoods in new ex situ reserves, away from their endemic locations with similar as well as different environmental conditions for testing their growth and survival capacities. In addition, other ex situ strategies involving biotechnological approaches for preservation of seeds, tissues, pollen and DNA in genebanks should also be fully exploited in the face of global climate change.

The effects of Norway spruce (Picea abies) seed treatment with cold plasma (CP), vacuum, and electromagnetic field (EMF) on germination and seedling growth are studied. CP treatments negatively affected germination ‘in vitro’, but for germination in cassettes CP (7 min) and EMF (5 min) significantly increased the germination yield. All treatments increase the germination rate in cassettes except CP (7 min) treatment having a negative effect. Seed treatment with CP and EMF increases the number of paramagnetic centers in dry seeds and modulate H2O2 production in germinating seeds. After the second vegetation season seedlings grown from CP (5 min) and CP (7 min) treated seeds, characterized by negative effects on either the germination rate or yield, have 50–60% larger height and 40–50% increased branching in comparison to the control seedlings.
