Аннотация: In this study, several alternative phytosanitary treatments for forest tree seeds in general were evaluated and experiments on the long-term storage of acorns were conducted. Seed treatments with low-energy electron beams were carried out on acorns, beechnuts, and seeds of Sitka spruce. This method, the effect of which is restricted to the outer seed parts, is based on the biological effect of ionising radiation and is intended to kill microfungi in the pericarp and testa. The second evaluated phytosanitary measure consisted of the microwave treatment of acorns, which relies on a thermal effect. In addition, the phenomenon of artificially induced frost hardiness of acorns was examined in order to explore the possibility of storing acorns at temperatures lower than the present limit of -3 C.

Аннотация: Shoots or twigs are placed in deep-freezes maintained at different temperature. The rate of cooling of the plant tissues depends on the temperature of the deep-freeze. It is more rapid than the rates usually emloyed in freezing tests. The merits and disandvatages of this freezing method are discussed. The degree of injury is determined by a modification of the conductivity method. The procedure has been used for determining changes in frost hardiness of Scots pine from October to May. The values obtained are reproducible, and even small changes in degree of hardiness of very hardy plant tissues may be determined by the method

Аннотация: A comparison between P. contorta and P. silvestris with reference to lignification, laboratory frost resistance and field hardiness, indicated that the Canadian pine, which withstands a Scandinavian climate far north of its seed source, presumably manages to do so in spite of a relatively low degree of winter adjustment in late September

Аннотация: The aim of the presnt work has been to find out whether or not it is possible to influence the water ceonomy and the development of frost hardiness of pine seedlings by fertilization with varying amounts of potassium, calcium, and magnesium and whether this can be done while maintaining a maximum or almost maximum growth rate. Simple and rapid methods have been used to allow rapid testing of the three ions in concentrations in shoots and in roots that are associated with rapid growth. There were no experiments with slow-growing seedlings suffering from severe deficiency

Аннотация: The effect of varying amounts of potassium and calcium on drought hardiness, transpiration rates, and water status of pot-grown seedlings of Pinus silvestris and Picea abies, 5 months old, was investigated. The positive correlation between potassium content of pine seedlings and survival at low water potentials could not be explained by low transpiration rate or early stomatal closure as the water potential decreased. It was assumed that the potassium contents influenced the desiccation of the cytoplasm, though the colloidal properties or the metabolism of carbohydrates and proteins.

Аннотация: The aim of the present work was to investigate the effect of mineral nutrition on frost hardiness. Frost hardiness in Scots pine with different concentrations of mineral nutrients in the needles was determined during winter by different freezing treatments. For the determinations, needles from a fertiliser experiment in central Sweden were used. The main effect of fertilisation on nutrient concentrations in the needle was on nitrogen, which showed a marked responce to treatment. Frost hardiness determinations were made by measuring the leakage of electrolytes from the needles. With freezing treatmen ts that caused heavy damage, there was a maximum hardiness at nitrogen concentrations of between 1.3 to 1.8 % dw, whilst with moderate damage, no such maximum could be detected. In this case, a tendency towards decreasing hardiness with incresing nitrogen concentration was observed.

Аннотация: The purposes of the present investigation was as follows: 1. To determine the photo- and thermoperiodic requirements of different populations for induction of frost hardiness. 2. To examine several characters to see if any could be feasible for tests at a young age.
