It was found that parthenocarpy could be induced by morphactin IT 3456 (0.5 and 1 ppm) in prior emasculated flowers, those left to free-pollination and even flowers pollinated with the pollen of control plants (New Yorker). When morphactin IT 3456 in 0.5 and 1 ppm concentrations was used 88% and 100% of parthenocarpy was noted in the greenhouse, respectively (Earliest of All). The higest percentage of parthenocarpy in the total number of fruits in the field was recorded in the 'New Yorker' variety. The lowest percentage of parthenocarpy was observed in the variety 903. The symptoms of the destructive influence of morphactin IT 3456 (0.5 and 1 ppm) on plant development were noted, but they were stronger in the greenhouse than in the field.

The influence of stage of fruit development and plant growth regulators on somatic embryogenesis and the relation of cultivar response on somatic embryogenesis and subsequent plant development have been investigated in eight cultivars of pecan [Carya illinoensis (Wangenh.) C. Koch]. Explants from the micropylar region of the ovule were more embryogenic when removed from fruits in the liquid endosperm stage than were intact ovules from less-mature fruits or from cotyledonary segments of more-mature fruits. Explants conditioned on medium containing auxin alone or auxin + cytokinin produced more somatic embryos than medium containing cytokinin alone. Under the conditions of this study, frequency of embryogenesis, as well as the germination of somatic embryos leading to plant development, indicated appreciable variation among cultivars. Plant development was greatest by far from somatic embryos of `Schley' than other cultivars studied.

Presentamos un trabajo de investigación empírico donde analizamos el uso de la ilustración en un medio concreto (The New Yorker) para contrastar el poder de transmisión del mensaje en un contexto muy concreto como es el de la pandemia mundial debido a la propagación de la covid-19. Metodología: Se ha llevado a acabo una triangulación metodológica combinando diversas técnicas y herramientas como la investigación documental, análisis descriptivo, focus group y análisis de contenido . Resultados: El análisis de 347 portadas revela que el elemento que varía de una publicación a otra es la ilustración.

The author reflects here on the important role that laughter has played in his life. His brother Murray laughs harder than anyone else he knows—and he caps it off by clapping in wild applause. The author's daughter, Eliza, once quipped: “We had laughter for dessert.” He even imagined a mystery story in which the murderer kills by devising a perfect joke that convulses people with laughter till they die. He also can remember a girl whose infectious laugh inspired a poem entitled Lily. His friend and Ping-Pong partner Bob Mankoff, the cartoon editor of The New Yorker, is a student of humor; he also teaches a class in humor theory at the University of Michigan. And like many long-married couples, he and his wife have developed routines for their own personal comedy team of sorts. The author adds that banter is a key ingredient of folk culture and family folklore.

Stoddard, president of the university from 1946 to 1953, was a controversial man, an East Coaster, a liberal, and an internationalist. Through much of his tenure he had difficult relations with both the university’s board of trustees and the state legislature, and he also faced opposition from conservative faculty at UI. A scandal over a phony cancer cure brought undesired publicity to the school and was the last in a series of controversies that led to his dismissal by the board in a late-night Illini Union meeting.
