Low-Temperature Effects on Photosynthesis and Correlation with Freezing Tolerance in Spring and Winter Cultivars of Wheat and Rye.
Winter cultivars of rye (Secale cereale L., cv Musketeer) and wheat (Triticum aestivum L. cvs Kharkov and Monopol), but not a spring cultivar of wheat (Glenlea), grown at cold-hardening temperatures showed, at high irradiances, a higher proportion of oxidized to reduced primary, stable quinone receptor (QA) than did the same cultivars grown under nonhardening conditions. In addition, there was ...
متن کاملFactors infl uencing somatic embryogenesis and regeneration ability in somatic tissue culture of spring and winter rye
Rye is an important crop in Northern and Eastern Europe. However, the application of various biotechnologies in rye breeding has been limited duo to its recalcitrant in tissue culture. In order to improve somatic tissue effi ciency, key factors affecting somatic embryogenesis and reproducible green plant regeneration of rye (Secale cereale L.) were evaluated and optimised. In this study, a tota...
متن کاملGazelle Companies: What Is So Special About the 20% Threshold?
In business analysis, a special emphasis is placed on “gazelles”, companies that grow by at least 20% per year for several years (usually four). While this 20% threshold is somewhat supported by empirical research, from the theoretical viewpoint, it is not clear what is so special about this value. In this paper, we provide a possible explanation for this empirical fact. 1 Formulation of the Pr...
متن کاملFoot and mouth disease in the mountain gazelle in Israel
A severe outbreak of infection with type O, aphthovirus occurred in the Ramot Yissakhar nature reserve (Israel) in April 1985, resulting in the death of about half of a population of some 3,300 mountain gazelles (Gazella gazella). A smaller outbreak occurred in the southern Golan nature reserve among about 6,500 gazelles. Both outbreaks were controlled by shooting gazelles in a buffer zone arou...
متن کاملThe Multi-Principal OS Construction of the Gazelle Web Browser
Original web browsers were applications designed to view static web content. As web sites evolved into dynamic web applications that compose content from multiple web sites, browsers have become multi-principal operating environments with resources shared among mutually distrusting web site principals. Nevertheless, no existing browsers, including new architectures like IE 8, Google Chrome, and...
