Explaining the physiological basis of rest or endodormancy (23) in seeds and buds has been the goal of considerable research effort within the past 40 years. One of the most popular approaches has been to study hormonal control, based on the hypothesis that growth-inhibiting compounds accumulate in buds and seeds as growth slows or seeds mature, and that these are metabolized, or that growth promoters are synthesized, or both, during subsequent exposure to rest-breaking treatments (moist chilling, dry after-ripening, exposure to light, etc.)
• In the article “Two Methods of Studying Rest: Temperature Alteration and Genetic Analysis”, by Frank G. Dennis, Jr.(HortScience 22(5):820–823, October 1987), Table 1 was printed incorrectly. The corrected table appears below.
The National Peach Council sponsored a workshop for scientists working on dormancy and hardiness of peach and other fruit trees on March 2, 1977 during its National Convention. The purpose of the workshop was to exchange ideas and to develop new ones with the aim of developing better techniques for preventing winter and spring freeze injury.
The workshop, attended mainly by participants from the Eastern U.S., included sessions on breaking and/or prolonging dormancy, environmental and cultural control of hardiness, freeze control systems, and natural control of hardiness. The following is a brief report on material covered. A more detailed report and a list of participants may be obtained upon request.
