Nutrient (N) stress affects cotton growth, primary physiological processes andfiber properties. This study utilized two sunlit growth chambers to compare cotton(cv. TM-1) responses to two levels of N nutrition imposed at the onset of floweringstage of development, 100 and 0% of optimum N, in plants grown under otherwiseoptimal temperature and soil moisture conditions. Flowers and bolls were tag...

Plants show phenological responses to herbivory. Some enclosure experiments have demonstrated that the onset of the peak flowering season is dependent on grazing pressure. We constructed a mathematical model using Pontryargin's maximum principle to investigate changes in flowering time by examining shifts in resource allocation from vegetative to reproductive plant components. We represented a ...

The Deleted in Azoospermia gene family encodes three germ cell-specific RNA-binding proteins (DAZ, DAZL and BOLL) that are essential for gametogenesis in diverse species. Targeted disruption of Boll in mice causes male-specific spermiogenic defects, but females are apparently fertile. Overexpression of human BOLL promotes the derivation of germ cell-like cells from genetically female (XX), but ...

Flat and cylindrical adhesive boll weevil, Anthonomus grandis grandis Boheman (Coleoptera: Curculionidae), pheromone traps captured significantly more (P < or = 0.05) boll weevils than the Hercon (Hercon Environmental, Emigsville, PA) trap during the late cotton-growing season, and larger adhesive areas were associated with higher captures; a flat plywood board collected the most boll weevils b...

A number of Eucalyptus species exhibit precocious flowering, flowering within a year of germination and often while still exhibiting juvenile foliage. To understand the nature of precocious flowering in Eucalyptus occidentalis, partial homologues of the inflorescence meristem identity gene TERMINAL FLOWER1 and of the floral meristem identity genes LEAFY and APETALA1 (EOTFL1, EOLFY and EOAP1, re...

No. Poster–73 IMPACT OF COTTON LEAF CURL DISEASE (CLCuD) ON YIELD AND QUALITY OF FIBRE IN Bt COTTON IN PUNJAB Daljeet Singh, J.S. Gill, R.K. Gumber and Ramandeep Singh Punjab Agricultural University, Regional Station, India Cotton is one of the most important cash crops in India. Cotton leaf curl disease (CLCuD) , caused by a single stranded circular Gemini virus consisting of DNA A and two sat...

Reintroductions of the boll weevil, Anthonomus grandis grandis Boheman, into areas of the United States where it has been eradicated or suppressed are very expensive to mitigate. There is concern that a cotton gin in an eradication zone may serve as a site of boll weevil reintroductions when processing cotton harvested in a neighboring infested zone. Similarly, there is a question whether weevi...

Gentiana leucomelaena manifests dramatic flower color polymorphism, with both blue- and white-flowered individuals (pollinated by flies and bees) both within a population and on an individual plant. Previous studies of this species have shown that pollinator preference and flower temperature change as a function of flower color throughout the flowering season. However, few if any studies have e...

1 This publication was developed to provide a summary of information about common boll-feeding bugs (heteropteran pests), stress proper identification of these pests, and acquaint the reader with the recommended strategies for management of boll-feeding bugs in cotton. The first section of this publication emphasizes the recent importance of boll-feeding bugs in cotton and provides a brief disc...
