Freezing tolerance of conifer seeds and germinants.
Survival after freezing was measured for seeds and germinants of four seedlots each of interior spruce (Picea glauca x engelmannii complex), lodgepole pine (Pinus contorta Dougl. ex Loud.), Douglas-fir (Pseudotsuga menziesii (Mirb.) Franco) and western red cedar (Thuja plicata Donn ex D. Donn). Effects of eight seed treatments on post-freezing survival of seeds and germinants were tested: dry, ...
متن کاملSurvival of microorganisms after ultrarapid freezing and thawing.
Numerous reports during the past 75 years have described, usually in qualitative terms, the survival of various bacteria, yeasts, and fungi after exposure to very low temperatures (Smith, Biological Effects of Freezing and Supercooling, p. 74-137, The Williams & Wilkins Co., Baltimore, 1961). Although rates of cooling and warming have been shown to affect survival quantitatively (Mazur, Ann. N....
متن کاملFungicidal Interference during Infection Related Developmental Stages in Magnaporthe Grisea
Rice blast, a serious epidemic disease that limits grain yield worldwide is caused by fungal pathogen Magnaporthe grisea. The present investigation was carried out to identify the probable avenues of interference by different fungicides during the critical stages of infection related morphogenesis of M. grisea. Effect of six fungicides at different stages of infection related morphogenesis show...
متن کاملNatural Freezing Survival in Animals
Natural freeze-tolerance supports the winter survival of many animals including numerous terrestrial insects, many intertidal marine invertebrates, and selected species of terrestrially hibernating amphibians and reptiles. Freeze-tolerant animals typically endure the conversion of 50% or more of total body water into extracellular ice and employ a suite of adaptations that counter the negative ...
متن کاملO-20: Slow-Freezing-Induced Changes of Birefringent Structures in Human Oocytes Are Related to Responsiveness to Ovulation Induction
Background: The slow-freezing method is one of the most popular techniques to freeze human oocytes and it is also used in routine in vitro-fertilization (IVF) programs, particularly in those countries where embryo freezing is not allowed. Slow-freezing damages some of the structures of the egg, among which the meiotic spindle (MS) and the zona pellucida (ZP). Polarized Light Microscopy (PLM) pe...
