Исследования интродуцированного японского сорта винограда Кёхо выполнены в нестабильных погодных условиях умеренно континентального климата юга России, в Черноморской зоне виноградарства Краснодарского края в условиях температурного и водного стрессов 2018 года. В период активной вегетации (май - август) сумма активных температур воздуха была на 197 °С больше среднемноголетней нормы, количество атмосферных осадков было меньше нормы в 3,7 раза и составило 47 мм. В аномальных погодных условиях интродуцированный сорт винограда Кёхо показал высокую адаптивность к нестабильным погодным условиям в форме активного роста и прохождения фенологических циклов. При остром дефиците атмосферных осадков и повышенной инсоляции продолжительность вегетации винограда Кёхо от распускания почек до полной физиологической зрелости ягод была равна 119 дней, на 5 дней меньше, чем у контрольного сорта Бригантина и на 3 дня меньше, чем в среднем по большой группе столовых сортов разного эколого-географического происхождения, расположенных рядом на Анапской ампелографической коллекции. Начало фазы распускания почек, роста побегов и соцветий наблюдалось 15 апреля, у контрольного сорта на 4 дня раньше, у сортов ампелографической коллекции на 6 дней позже. Продолжительность этой фазы вегетации у изучаемого сорта составила 54 дня, больше на 11 дней чем у контрольного сорта и на 9 дней чем у столовых сортов ампелоколлекции. Цветение у сорта Кёхо начиналось 7 июня, на 15 дней позже чем у контрольного сорта Бригантина и на 3 дня чем у группы столовых сортов на ампелоколлекции. Продолжительность периода от начала цветения до начала созревания ягод у сорта Кёхо в экологических условиях 2018 года составила 50 дней, что на 4 дня короче, чем у контрольного сорта и на 3 дня короче, чем у сортов на ампелоколлекции. Интенсивность роста ягод была более высокой по сравнению с контролем и группой столовых сортов в ампелоколлекции. Полная физиологическая зрелость ягод у изучаемого сорта наступила 11 августа, практически одновременно с контролем - 12 августа.The study of introduced Japanese grapevine cultivar ‘Kёho’ was carried out in unstable weather conditions of moderately continental climate of the South of Russia, in the Black Sea viticultural zone of the Krasnodar Krai under temperature and water stress of 2018. During the active vegetation season (May - August), the accumulated effective temperatures made 197 ° С above the long-time average annual, the amount of precipitation was 3.7 times less than normal, and amounted to 47 mm. Under the effect of abnormal weather conditions, the introduced grapevine cultivar ‘Kёho’ demonstrated high adaptability to erratic weather conditions during the active growth phase and passage of phenological cycles. Under acute atmospheric precipitation deficit and increased insolation, the duration of ‘Kёho’ grapevine vegetation from bud break to full physiological berry ripeness made 119 days, which is 5 days less as compared to control cultivar ‘Brigantina’ and 3 days less than the average for a large group of table cultivars of various ecological and geographical origin, located in the nearby Anapa ampelographic collection. The start of the bud break, shoot and inflorescence growth phase was observed on April 15; it happened 4 days earlier for the control cultivar, and 6 days later for the cultivars in the ampelographic collection. The duration of this vegetation phase for the studied cultivar was 54 days, which by 11 days exceeded that of the control cultivar and by 9 days that of the table cultivars in the ampelographic collection. The bloom of ‘Kёho’ began on June 7 - 15 days later than that of the control cultivar ‘Brigantina’ and 3 days later as compared to the group of table cultivars in the ampelographic collection. Duration of the early bloom to veraison period of ‘Kёho’ grapes in the ecological conditions of 2018 made 50 days, which was 4 days shorter than that of the control cultivar and 3 days shorter as compared to the cultivars in the ampelographic collection. The berry growth was more intensive as compared to the control and the group of table cultivars in the ampelographic collection. Berries of the studied cultivar reached full physiological ripeness on August 11, almost simultaneously with the control - on August 12.

Field and laboratory experiments have shown the importance of a period of "cold-rest" at a temperature below the threshold of development as a requirement for overcoming diapause in the spruce sawfly, especially in stock from a one-generation area. After cold-rest, maximal development results at a temperature of 74° to 75° F. or higher, and after contact with water. Temperatures in the field are lower and fail to promote so high development as may be obtained in the laboratory; however, temperature variations between 65° and 45° F. evidently have little influence on the degree of emergence from the diapause condition, though speed of development is directly affected. The benefit of contact with water is reduced or lost if contact occurs only while soil temperature remains below the threshold of development, and if the moisture taken up in the cocoon wall is lost by evaporation before it can be absorbed by the larva. The role of the cocoon in water exchanges, and differential effects of abnormal weather conditions upon intracocoon development in stocks in one-generation and two-generation areas, are described.

The extent of ice cover in Hudson Bay was investigated during the Spring of 1948 by the RCAF and interested governmental departments. A series of reconnaissance flights over the Bay in March and April disclosed that it was virtually ice-bound from shore to shore. Large areas of open water were observed during the period May 3rd to May 6th. An inspection of the synoptic weather charts disclosed that weather conditions over the Bay both prior to and during this period were abnormal. This immediately suggests that the ice conditions observed might not be representative. For an appraisal of the observations it is necessary to determine the effects of the abnormal weather on the ice. The observed ice conditions are mentioned and the causes of open water areas briefly discussed. The severity of the winter at Churchill was investigated to determine the normalcy of the ice development. A protracted thaw over the eastern parts of Hudson Bay is disclosed by reference to the weather charts. The correlation between the mean monthly temperatures for the spring months and the date of ice clearance at Churchill Harbour is then investigated to determine the effects of a protracted thaw on the ice.
