Studies by LE CLERC DU SABLON ill 1905 (5) established the general naturle of the changes oceurringo in the fruits of Cueurbits during maturationi anid storage. At matuiity the solids of the fruits of Cucurbita pepo var. couroge olive were high in starch and relatively low in sugar. During storaoe the conversion of stareh to sugar was rapid, as was also the loss of sugar by respiration. On long...

In this work, the part of the squash core collection, maintained in the Greek Gene Bank, was assessed using the morphological and molecular data. Sixteen incompletely classified accessions of the squash were characterized along with an evaluation of their resistance against two isolates of Fusarium oxysporum. A molecular analysis using Random Amplified Polymorphic DNA (RAPD) markers was also pe...

The formation or suppression of particular structures is a major change occurring in development and evolution. One example of such change is the absence of the seventh abdominal segment (A7) in Drosophila males. We show here that there is a down-regulation of EGFR activity and fewer histoblasts in the male A7 in early pupae. If this activity is elevated, cell number increases and a small segme...

Although many fungicides are registered for use to control powdery mildew on cucurbits, management of resistance to fungicides in pathogen populations still remains a major challenge. Two biopesticides Regalia SC and HMO 736 were evaluated in the greenhouse and field for their efficacy against powdery mildew in squash. In greenhouses, Regalia SC alone significantly (P < 0.05) reduced powdery mi...

The green lacewing, Chrysoperla carnea (Steph.) (Neuroptera: Chrysopidae), is a generalist predator in its larval stage of most species of soft bodied insect pests, especially aphids, whiteflies, thrips, coccids, and mealy bugs. This predator had been recorded in different regions in Saudi Arabia as indigenous species. The fitness of this indigenous predator for controlling the aphid, Aphis gos...

Abstract Papaya ( Carica papaya ) seeds together with squash Cucurbita moschata was pelleted to be used as dewormer, determine its antihelmintic effects on growing chicken. They were randomly divided into four treatments and replication five birds per treatment assigned using Randomized Complete Block Design (RCBD), a total of eighty native chickens. The were: Treatment A - Control (commercial ...

For plant viruses to systemically infect a host requires the active participation of viral-encoded movement proteins. It has been suggested that BL1 and BR1, the two movement proteins encoded by the bipartite geminivirus squash leaf curl virus (SqLCV), act cooperatively to facilitate movement of the viral single-stranded DNA genome from its site of replication in the nucleus to the cell periphe...

TWENTY-FIVE YEARS AGO, SINOWAY et al. (13) ingeniously introduced the world of physiology to a simple yet unique model of investigating exercise-induced vascular adaptations. The model consisted of the examination of dominant and nondominant arms of tennis players to elucidate the localized impact of physical activity on the vasculature. This well-designed experimental paradigm provided evidenc...

Two greenhouse experiments were conducted to examine the effect of Crotalaria juncea amendment on Meloidogyne incognita population levels and growth of yellow squash (Cucurbita pepo). In the first experiment, four soils with a long history of receiving yard waste compost (YWC+), no-yard-waste compost (YWC-), conventional tillage, or no-tillage treatments were used; in the second experiment, onl...

The progress in the cytogenetics of sugarcane with special reference to researches during the last decade is reviewed. Standardisation of leaf squash, pollen grain squash and root t ip squash methods for chromosome study have been reported. Culturing of pollen grains and cells in vitro have been new additions. The basic chromosome number of Saccharum may be 5, 6, 8 and 10. A new line of investi...
