BACKGROUND The DefH9-iaaM gene fusion which is expressed specifically in placenta/ovules and promotes auxin-synthesis confers parthenocarpic fruit development to eggplant, tomato and tobacco. Transgenic DefH9-iaaM eggplants and tomatoes show increased fruit production due mainly to an improved fruit set. However, the weight of the fruits is also frequently increased. RESULTS DefH9-iaaM strawb...

Pollination services of pumpkin, Cucurbita pepo L., provided by the European honey bee, Apis mellifera L., were compared with two native bee species, the common eastern bumble bee, Bombus impatiens (Cresson), and Peponapis pruinosa Say, in New York from 2008 to 2010. Performance of each species was determined by comparing single-visit pollen deposition, percentage of visits that contacted the s...

Industrial hemp ( Cannabis sativa ) cultivars used for flower, fiber, or seed production are usually considered short-day plants and flower in response to photoperiod. However, some of day-neutral, where induction may be independent daylength. Day-neutral were planted before recommended dates studied field experiments conducted Watkinsville, GA, Spring 2020 2021. (Pipeline Maverick) photoperiod...

saffron is the most important iranian non oil export. improper conditions of saffron flower storage increases microbial contamination and decreases saffron quality. this study was done for prolonging the shelf life of saffron flower in modified atmosphere packaging and subsequent to producing a new method for exporting the fresh saffron flower as cut flower. saffron flowers were packed in a pol...

To study interferential effect of lamb's-quarters (Chenopodium album L.) on marigold (Calendula officinalis) yield and lamb's-quarters seed production two factorial field experiments were conducted in Tabriz, Iran, during 2010-2011. Treatments were densities of lamb's-quarters (0, 2, 4, 6 and 8 plants per meter row) and relative times of its emergence (0, 10, 20, 30 and 40 days after marigold e...

The effect of mechanical stress created by pruning of lateral branches on sex expression in cucumber cultivar, “Sialkot Selection’ was examined. Seeds were sown in the field and after reaching the required number of lateral branches according to respective treatment, each new coming lateral branch were pinched off. The pruning treatments included; main stem without any lateral branches (T ) and...

Salicylic acid (2-hydroxybenzoic acid) may help regulate several plant functions, including systemic acquired resistance to pathogens and the formation of flowers. The objective of this study was to characterize the effects of foliar-applied salicylic acid on cotton (Gossypium hirsutum L.) flowering, boll retention, and yield. Field experiments were conducted at two Mississippi locations in 199...

Almond tree yield is a function of the number of flowers on a tree and the percentage of flowers that set fruit. Almonds are borne on spurs (short proleptic shoots that can have both leaves and flowers). Almond tree spur dynamics research has documented that previous year spur leaf area is a predictive parameter for year-to-year spur survival, spur flowering and to a lesser extent spur fruiting...

Sapium sebiferum (Linn.) Roxb. (Chinese Tallow Tree) is a perennial woody tree and its seeds are rich in oil which hold great potential for biodiesel production. Despite a traditional woody oil plant, our understanding on S. sebiferum genetics and molecular biology remains scant. In this study, the first comprehensive transcriptome of S. sebiferum flower has been generated by sequencing and de ...
