SUMMARYExperiments, conducted over 3 years, investigated the effect of all combinations of two storage periods at low temperature (0 or 2 °C) and two storage periods at 10 °C on the sprout growth, numbers of stems per tuber, foliage development and subsequent tuber yield of the two maincrop varieties Maris Piper and Désirée.Although the number of day-degrees accumulated during sprouting was the same for all treatment combinations, there were large effects of treatments on the number of sproutlets per tuber and the total sprout length per tuber. However, there was no effect on the number of stems per tuber, foliage development or saleable ware yield inany year.

A fall lifting and overwinter storage trial on 3+0 white pine (Pinus strobus L.) was carried out at St. Williams forest tree nursery (42° 40′N, 80° 25′W) during two consecutive years to study: (1) the degree hardening day (DHD) requirement for lifting; and (2) the effect of different storage temperature regimes: cold (1-4 °C) and frozen (−3 °C) on the performance of stock stored overwinter. Field performance was best if lifting for overwinter storage was delayed until after an accumulation of 125 DHD which is less than that required farther north. In some instances, seedlings lifted very late in the year had reduced survival and growth in the following year. Seedlings were ready for cold storage before being ready for frozen storage. Frozen storage is preferred owing to molding problems associated with cold storage.

ABSTRACT The hygienic consequences of the temperature regimes experienced by perishable product during storage, transport, and display can be assessed by a temperature function integration technique. The technique requires the collection of appropriate temperature histories from product units moving through a process and integration of the histories with respect to suitable models which describe the dependency on temperature of the growth of bacteria of concern. The distributions of the proliferation values obtained are characteristic of each process. However, when the duration of a process is highly variable for individual units passing through it the fundamental characteristics of the process may be difficult to discern from proliferation data. Then, a storage efficiency factor can be calculated from a proliferation value and the duration of each temperature history, and the distributions of those factors used to assess and compare processes. Procedures for the collection and analysis of product temperature history data from product cooling, storage, distribution, and display processes, and the use of such data for process assessment are discussed.
