Use of the calorimetric and dilatometric methods for determination of ice in frozen tissues is criticized, and a method based on terminal melting points determined after various degrees of drying is proposed. The theoretical background of such a method lends support to it, and experimental work with gelatin is especially convincing. Use of the dehydration – melting point method on blood of Loxostege sticticalis gave results conforming in general to those obtained by other workers with calorimetric and dilatometric techniques, and also to those obtained with salt solutions. The amount of water that is bound is shown to be very low, as in mammalian, frog, and fish muscle. The possible influence of bound water in insect cold-hardiness is discussed and the conclusion is reached that it has little if any protective effect.

Microcomputer-based thermal analysis (TA) was conducted on dormant mixed buds of Japanese persimmon (`Hiratanenashi'). The exotherms of buds were detected by thermoelectric modules. Flower buds of peach (Prunus persica Batsch cv. Shimizuhakuto) were also analyzed. When TA was used on a whole excised bud, including bud scales, the persimmon buds had only one exotherm at –14.3 °C, while the peach buds had high and low exotherms at –8.4 °C and –14.1 °C, respectively. However, when the exotherm was measured for the primordium, with the bud scales and transitional leaves removed, each primordium showed only one exotherm at –20.7 °C in persimmon and –11 °C in peach. Determination of killing temperature by visual observation, electrolyte leakage method, and triphenyltetrazolium chloride test revealed that the primordium of the persimmon bud was killed at about –14 °C as the excised whole bud or as the whole bud attached to the branch segment. Using the same method, the naked primordium was killed between –22 °C and –25 °C as the primordium was cooled. The peach primordium was killed at –14 °C when examined as a whole bud and at –11 °C as a naked primordium. Furthermore, the exotherm temperatures of persimmon buds and stem segments were measured at appropriate intervals during the two winter seasons 1993–95. Exotherm temperatures of persimmon buds were always higher than the low-temperature exotherm (LTE) temperatures of the stem segments and lower than the high-temperature exotherm (HTE) temperatures of the stem segments. LT50 of persimmon buds almost coincided with the exotherm temperatures of buds. A postulated role of bud scales in supercooling is discussed.

Dose Levels

The response of grapevines to methanol was investigated at the Orchard Mesa Research Center in Grand Junction, CO. Optimum sublethal methanol dose levels, based on visual assessments, were 90% for leaves and 100% for trunks for 10 cultivars. Total soluble sugars (TSS) of the berries, monitored every week until harvest, showed significant differences with Muscat Blanc during veraison. Berries from the methanol-treated vines had higher TSS (16.4 °Brix) than controls (15 °Brix). However, no significant differences were observed later in the season when approaching fruit maturity. At harvest, data on yields as estimated by cluster weight, berry weight and berry size showed no differences between the two treatments. Methanol did not enhance cold hardiness of bud tissues. measured by differential thermal analysis. It was concluded that, although methanol has been reported to improve several physiological features of C3 crops, our study suggested that it has little or no practical effect on grapes. More data on the determination of sugars in berries by HPLC will be discussed.

Probe Measurements

This paper deals with probe measurements of low frequency resistance (RLF), high frequency resistance (RHF), and resistance index (= 100 x RLF/RHF), for the determination of cold hardiness or the injury caused by cold treatments. Populations of white clover (Trifolium repens L.) were subjected to different periods of freezing. Discrimination between treatments could be made in terms of RLF, RHF, and resistance index, though discrimination in terms of RHF is poor. The rest of the paper deals with lucerne (Medicago sativa L.). Measurements were made after a cold treatment on field plants consisting of four commercial strains and their F1 crosses, and also on F2 seedlings. RLF and the resistance index appear to be equally good predictors for the recovery of strains or of individual plants from such populations. The Appendix deals with measurements on commercial (tetraploid) plants, diploids, and colchicine-produced tetraploids.

The superb flavor of trailing blackberry cultivars, such as `Marion', is derived from Rubus ursinus Cham. & Schlecht. Wild R. ursinus offer a range of horticulturally desirable traits to breeders, from high fruit quality to improved cold hardiness. Current cultivars are derived from relatively few sources of R. ursinus, selected primarily for fruiting characteristics. A replicated field trial of 460 clones, representing 20 populations from southern British Columbia, Washington, and Oregon, was established in 1994. Observations during the planting year have indicated that monitoring variability in the following reproductive traits will be useful in assessing diversity; budbreak, flowering, and fruiting date; lateral length; proportion of reproductive laterals; gender; flower and fruit number; and fruit size. In particular, there are clones that exhibit large fruit size (4 to 5 g), high flower number per lateral, and uniform fruit set. Analysis of these data will contribute to determination of relative genetic distances among the populations and enhance the understanding of the diversity available in R. ursinus.
