Vernalisation Requirement

Low temperatures in the autumn induce enhanced expression/relative accumulation of several cold-inducible transcripts/proteins with protective functions from Late-embryogenesis-abundant (LEA) superfamily including dehydrins. Several studies dealing with plants grown under controlled conditions revealed a correlation (significant quantitative relationship) between dehydrin transcript/protein relative accumulation and plant frost tolerance. However, to apply these results in breeding, field experiments are necessary. The aim of the review is to provide a summary of the studies dealing with the relationships between plant acquired frost tolerance and COR/LEA transcripts/proteins relative accumulation in cereals grown in controlled and field conditions. The impacts of cold acclimation and vernalisation processes on the ability of winter-type Triticeae to accumulate COR/LEA proteins are discussed. The factors determining dehydrin relative accumulation under controlled cold acclimation treatments versus field trials during winter seasons are discussed. In conclusion, it can be stated that dehydrins could be used as suitable indicators of winter survival in field-grown winter cereals but only in plant prior to the fulfilment of vernalisation requirement.

Duration Of Copulation

AbstractLaboratory and field experiments indicate that the female spruce budworm (Choristoneura fumiferana (Clem.)) pupal stadium requires approximately 122C degree-days above a threshold of 7.2 °C (45°F), the male 124. Emergence time on any given day depends on temperature but is independent of photoperiod. Under field conditions male and female budworm mate only once per 24-h period. In the laboratory under continuous illumination females mate repeatedly and males readily mate a second time within a few hours, but the duration of the second copulation is abnormally long. The probability of multiple matings under field conditions is reduced by the restricted period of sexual activity coupled with the duration of copulation and the lower competitiveness of mated insects. Antennae are essential to the male for successful copulation.

Electronic communication has become an essential part of consumers' everyday lives. Consumers rely on the internet as an alternative source of information pertaining to brands that can be accessed easily. As a result, electronic word of mouth (e-WOM) has become a force to be reckoned with that needs to be understood in order to be properly managed. This research investigates how the credibility of the brand as a source of information might be influenced by consumers' engagement in e-WOM and whether this influence subsequently reflects on their purchase intentions. The research findings indicate that indeed there is a relationship between e-WOM and brand credibility that reflects both directly and indirectly on the consumer's purchase intentions. Based on this, several recommendations are developed to help managers navigate their online presence in a way that specifically suits their consumers' internet usage patterns, in order to effectively manage available e-WOM on their brands.

Field experiments were conducted to determine the relationship of tomato anthracnose to weather variables. Sixteen potted tomato plants were exposed to field conditions within rows of tomato plants for 4 consecutive days at various time periods during the 1993 and 1994 summer growing seasons. Incidence of fruit infection by Colletotrichum coccodes was correlated with rain variables (amount and duration of rain) alone and in combination with other meteorological factors. The best fitting regression equation, accounting for 72% of the variation in anthracnose incidence (arcsine-square root transformed), was Y = 111.77 - 1.16 HNRo, in which HNRo is the numbers of hours during which no rainfall occurs within 4-day intervals that tomato fruit were exposed to field conditions in central Pennsylvania.

Autors was designed a system to modify the SPC romanian seeding machine for in order that it can be used for no-till technology. This machine was manufactured with the help of S.C. MECANICA M.A.R.I..U.S. S.A. in Cluj- Napoca and it was used in laboratory conditions in a state of the art soil bin of Hohenheim University, Stuttgart and in laboratory-field conditions. The field experiments were located on a plot of Experimental Teaching Facility of USAMV Cluj-Napoca, on aluviosol molic soil after SRTS – 200, in location Lunca Someşului Mic (Podişul Someşan) .
