A guide to insect injury of conifers in the lake States
[Текст] : путеводитель / L.F. Wilson . - Washington : USDA Forest Service, 1977. - 218 с. : figures. - (Agriculture Handbook ; 501). - Библиогр: В надзаг.:. - 1-00 р.
Аннотация: The guide deals with the insects, important members of natural communities, often feed and live on trees, sometimes damaging them.Conifers have economic value fot lumber, paper, and Christmas trees, as well as aesthetic vavue around homes, in parks and etc.Insect and disease can reduce the value of this resource. This guide is needed to help identify conifer insects by the damage they do.

Spring frosts: with special reference to the frosts of May 1935
[Text] : научное издание / W. Day, T. Peace. - London : Majestry's Stationery Office, 1937. - 131 p. : карты, рис., табл. - (Forestry Commission Bulletin ; № 18). - eng. - Библиогр.: 130-131. - 5.00 р.
Аннотация: More alarm was caused by the mid-May frosts of 1935 than by any occurrence of the kind during recent years. Practically everyone connected with the growing of plants was affected. The frosty conditions covered the whole of Britain and caused general injury to plant life, and especially to trees.

Cold damage and plant mortality in experimental provenance plantations with Scots pine in Northern Sweden
[Text] = Koldskador och plantdod i proveniensforsok med tall i Norrland : монография / V. Eiche. - Stockholm : Skoghogskolan, 1966. - 219 p. : рис., табл. - (Studia Forestalia Suecica, ISSN 0039-3150 ; № 36). - eng. - Библиогр.: c. 205-212. - 2.20 р., 4.50 р.
Аннотация: The book deals with general information on experimental plantations, weather conditions during the years when severe injury to plants occurred; injury to plants and damage patterns; mortality rates in plants among provenances; cause of damage to plants; cold damage, healing of wounds and mortality-connected phenomena in a chain of biological processes in plants

Frost hardiness in Scots pine (Pinus silvrstris L.) I. Conditions for test on hardy plant tissues and for evaluation of injuries by conductivity measurements
[Text] = Frosthardighet hos tall (Pinus silvestris L.) I. Metoder for testning av hardigt plantmaterial och for bestammning av skador med ledningsformagematningar : научное издание / A. Aronsson, L. Eliasson. - Stockholm : Skogshogskolan, 1970. - 30 p. : рис., табл. - (Studia Forestalia Suecica, ISSN 0039-3150 ; № 77). - eng. - Библиогр.: с. 26-28. - 0.30 р.
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

Mannyn taimen kehitys latvan katkeamisen jalkeen
[Text] = Recovery of young Scots pines from stem breakage : научное издание / K. Loyttyniemi. - Helsinki : Metsantutkimuslaitos, 1983. - 11 с. : рис., табл. - (Folia Forestalia ; № 560). - fin. - Библиогр.: с. 10. - ISSN 0015-5543. - ISBN 951-40-0625-9 : Б. ц.
Аннотация: The effect of moose (Alces alces) damage on the development of young Scots pines was investigated by simulating the damage by breaking off the top part of the stem and by following the recovery of the trees after the injury.
