Abstract:

In the preemergence test, azafenidin, flufenacet, thiazopyr, isoxaben, dithiopyr, and thifensulfuron exhibited safety on cantaloupes and watermelon at rates higher than rates required for effective weed control. In the postemergence test, the margin of selectivity for melon safety and weed control was narrow for MKH-6561, flufenacet, and thifensulfuron. MKH-6561 and CGA-362622 applied preemergence did not offer any acceptable crop safety relative to the weed control that was observed. Azafenidin, thiazopyr, isoxaben, and pyrithiobac did not demonstrate adequate melon safety compared to providi

Abstract:

Sodium chlorate exhibited the fastest developing crop phytotoxicity symptoms within 3 days after treatment (DAT). Within three days of application, significant crop injury at 40 and 80% was observed on cantaloupes for sodium chlorate applied at 1.0 and 4.0 lb AI/A, respectively. Thidiazuron/diuron (Ginstar7) caused injury that was slightly slower to develop and the crop declined severely during the next 10 days. Ginstar at 8.0 or 12.0 oz product/A initially caused 20% crop injury. Thidiazuron (Dropp7) caused the least injury on cantaloupes and injury reached unacceptable levels at 1 WAT. Dropp

Abstract:

Seventeen herbicides recently gaining registrations in corn, soybeans, or other major crops were evaluated in screening tests for potential use in melons. In a preemergence herbicide screening test, flumioxazin, dimethenamid, halosulfuron, and s-metolachlor demonstrated melon crop safety at rates higher than rates for effective weed control. In a postemergence screening test, halosulfuron and rimsulfuron gave acceptable weed control with adequate crop safety.

Rising water costs and concern for groundwater contamination are forcing melon growers to improve irrigation and nitrogen fertilization efficiency. The research objectives were: 1) to determine quantities of nitrogen and water applied through a subsurface drip irrigation system to cantaloupe and watermelon which would optimize fruit yield while minimizing losses of nitrogen and; 2) to develop specific monitoring techniques for assessing the water and nitrogen status of melon crops throughout the growing season.

The single-step derivatization procedure is highly reproducible and allows simultaneous analysis of asparagine and glutamine together with their corresponding acids.

Abstract:

Au cours de ce travail nous avons cherche a preciser l'intervention potentielle du calcium dans la reponse au stress chez le melon. Le calcium est un element nutritif indispensable qui intervient au cours du developpement des plantes et dans la mise en place des mecanismes de defense en reponse a une agression par un stress biotique et abiotique. Ceux-ci en declenchant la biosynthese d'ethylene, peuvent etre un facteur responsable de pertes observees au cours de la conservation. Le role de la nutrition calcique et de conditions climatiques variables sur le metabolisme de la plante et du fruit

Abstract:

The effect of three different release rates (1x, 10x, and 20x the recommended rate of 10,000/acre) of Eretmocerus eremicus, a whitefly parasitoid, on sweet potato whitefly populations in cantaloupe were evaluated against populations in untreated control plots. Parasitoids were released from a point source in the center of each of nine treatment plots. All stages of whitefly development were monitored within a 10-m annulus surrounding each release point in all 12 plots, as were rates of parasitism. This occurred over a 52-d period from July 21 through September 11, 2001. The rates of sweet pota

Resumo: O objetivo deste trabalho foi determinar a dinâmica de crescimento das plantas, a marcha de acúmulo de nutrientes da cultura e as modificações químicas no substrato composto por areia e casca de amendoim. O híbrido 'Fantasy' foi conduzido em vasos com substrato (mistura de areia e casca de amendoim em partes iguais). A irrigação foi realizada por gotejamento com solução nutritiva recomendada para a cultura em cultivo hidropônico. A amostragem para a determinação da dinâmica de crescimento, marcha de acúmulo de nutrientes e modificações químicas do substrato foi realizada em seis épocas

Abstract:

The general aim of this PhD thesis was to study, develop and apply different breeding techniques in melon species in order to produce new commercial cultivars. The three specific objectives of this thesis are: 1. To study and evaluate the commercial value and the parthenogenetic capacity of seven genotypes of C. melo var. Inodorus “Piel de Sapo” type to obtain DH lines which might be further used as parental lines for commercial hybrid F1 seed production. The parthenogenetic generation of DHs from the seven genotypes was evaluated and optimized through the analysis and description of the di

Abstract:

L'hormone vegetale ethylene joue un role majeur dans des nombreux aspects du developpement des plantes, en particulier dans la maturation des fruits climacteriques. Chez certains de ces fruits, comme les melons cantaloup charentais (cucumis melo var. Cantalupensis, naud) la production d'ethylene lors de la crise climacterique est forte et rapide, ce qui a pour consequence une maturation rapide et une conservation de tres courte duree prejudiciables au transport et a l'expansion commerciale du produit. De ce fait, l'ethylene constitue un bon cible pour la manipulation genetique de la maturation

Abstract:

Studies were conducted in the field and laboratory to investigate how the addition of spray adjuvants to Success affected its insecticidal activity against leafminers, thrips and lepidopterous larvae. Studies were also designed to evaluate the knockdown and residual mortality of Success against worms when applied with a buffer to produce an acidic spray solution. Results indicated that Success applied without an adjuvant appeared to provide the most consistent adult mortality of Liriomyza leafminers. In contrast, the addition of a penetrating surfactant (crop oil concentrate) resulted in signi

Abstract:

The increase of ethylene production in ‘Cantaloupe Vedrantais’ melon is one of the main causes of the pre and post harvest alterations. In order to extend the shelf life of this fruit, melon plants were transformed with an ACC oxidase DNA sequence of "Royal Gala" apple in antisense orientation (pAP4). Three transformants were obtained. One of them showing the greatest reduction in ethylene production (AS3) was analysed further and used as a model to discriminate between ethylene- dependent and ethylene-independent processes during fruit ripening. AS3 melons exhibited a delay of about 10 days f
