Berry formation is the process of ovary conversion into a functional fruit, and is characterized by abrupt changes in the content of several phytohormones, associated with pollination and fertilization. Much effort has been made in order to improve our understanding of berry development, particularly from veraison to post-harvest time. However, the period of berry formation has been poorly inve...

Information from Literature Much has been published about pollination, pollinators, pollinizers, fertilization and fruit set in text books and periodicals. The definitions are not difficult. Pollination is the movement of pollen among compatible flowering plants (cross-pollination) or from anthers to stigmas on the same plant or different plants of the same clone (self-pollination). Many plants...

BACKGROUND AND OBJECTIVES Postoperative pneumoperitoneum following laparoscopic surgery is self-limited, typically resolving within days. METHODS We analyzed the case of a 48-y-old woman who presented with acute abdominal pain 48 d after a total laparoscopic hysterectomy. Imaging studies revealed free air under the diaphragm suggesting a perforated viscus. RESULTS An exploratory laparotomy ...

Abstract Pollination of deceptive orchids has enabled scientists to understand how these species avoid inbreeding depression by reducing the number pollinator visits per inflorescence. In rewarding species, which receive a higher rate plant, geitonogamy is usually and therefore risk increases. this study, we assess breeding system orchid A. coriophora, spatio-temporal changes in its fitness as ...

Pollen pistil interaction studies were carried out in six sunnhemp genotypes. viability percentage of the genotypes ranged from 0.0 to 93.5% and pollen germination 84.0% at four different floral stages starting bud opening a flower. The viable grains present later three flower for globose type anthers, while two heart shaped anthers. Stigma receptivity was high very during S3 S4 stages. Artific...

The role of gibberellins (GAs) in tomato (Solanum lycopersicum) fruit development was investigated. Two different inhibitors of GA biosynthesis (LAB 198999 and paclobutrazol) decreased fruit growth and fruit set, an effect reversed by GA(3) application. LAB 198999 reduced GA(1) and GA(8) content, but increased that of their precursors GA(53), GA(44), GA(19), and GA(20) in pollinated fruits. Thi...

Citrus rootstock breeding is important to improve their resistance diseases, pests and adverse environmental conditions. The majority of citrus species have nuceller embryony. Although Clementine mandarin monoembryonic, in some cases (intercrossing etc.) abortive seed formation can be seen frequently. In this study, × Carrizo citrange were crossed. the interspecies hybridization (Citrus Ponciru...

To the Editor: Hospital and public health personnel are currently receiving smallpox vaccination in a national effort to increase preparedness for a possible deliberate release of smallpox (1). Generalized vaccinia (GV) is a typically self-limited adverse event following vaccination (incidence 23.4–238.2 cases per million primary vaccinees and 1.2–10.8 cases per million revaccinees) (2,3). We r...
