Effects of excess nitrogen on growth, flowering and fruit set of bell pepper (Capsicum annuum L.)
… of excess N at transplanting a growth, yield and fruit set of bell pepper (Capsicum annuum L. cv. 'Lady Bell'). The rates were 112, 224, 336 and 448 kg N/ha. Excess N at transplanting did not stimulate vegetative growth, but rather suppressed plant growth, particularly at early growing period. In …

Responses of Arthropods to Fire and How Pollinators and Pollination Services Are Affected by Fire Severity
… to determine how floral visitors impacted fruit set of wax currants (Ribes cereum). We found that there was no difference in floral visitor communities or fruit set of wax currants across fire severity but that the pollinator exclusion treatment did have a significant impact on fruit set, …

Refining Fruit-Zone Leaf Removal for Red-Fruited Bordeaux Grape Varieties Grown in a Humid Environment
Current fruit-zone management recommendation in the eastern US aims for 1-2 basal shoot leaf layers after fruit set to limit fungal disease and sunburn incidence, and prevent extreme heating of grapes. The goal of this work was to assess if fruit-zone leaf removal to an uncommonly greater extent, …

Inhibition of Flower Bud Initiation and Development in Apple by Defoliation, Gibberellic Acid and Crop Load Manipulation
… and more extensively in apple than in any other fruit tree; however, it remains a serious problem in commercial apple production all over the world. Trees that have become biennial flower profusely and carry a heavy crop in the "on" year, and flower sparsely or not at all and carry little or no …

Sera domates yetiştiriciliğinde 2,4-D, 4-CPA ve Noxa'nın meyve tutumu üzerine etkisi
… Abstract The effects of 2,4-D, 4-CPA and NOXA on fruit set, yield, fruit form and vegetatif organs in greenhouse tomatoes were investigated. As plant material, Carpy natural partheno- carpic variety. Amfora and Dario hybrid tomatoes cultivars were used. 2,4-D at 1.0, 2.5, 5.0 mg/1 4-CPA at 7.5, …

Optimizing grape cluster exposure to increase desirable aroma compounds and decrease disease severity
By increasing fruit exposure to sunlight and influencing fruit development, leaf thinning in the fruit zone can improve grape quality and lower disease incidence; however, further investigations on the timing, varietal response and intensity are needed to optimize results and to better understand …

Performance of selected different types of stone fruits in a summer rainfall area, South Africa
Temperate fruit trees cultivated in areas of mild winter conditions result in a number of insufficient chilling symptoms. Such insufficient symptoms are described in general as the absence of bud break, delayed foliation, reduced fruit set as well as reduced fruit quality. Therefore, after bud …

The reproductive ecology of Minuartia patula Michx. Mattf. (Caryophyllaceae)
… us about M. patula? 3) Are there differences in fruit set, seed set and germination rates among populations of Minuartia patula? Based on caging studies, flower phenology and pollen to ovule ratio, M. patula can be considered a facultative autogamous species. Also, significant differences were …

Identification Of Candidate Genes For Self-Compatibility In A Diploid Population Of Potato Derived From Parents Used In Genome Sequencing
… used in potato genome sequencing, we observed fruit set on many greenhouse-grown plants. Subsequently, after controlled self-pollinations, we confirmed fruit set in 32 of 103 F1 plants. Our goal was to identify genes responsible for self-compatibility in this population and to advance selfed …

The Impact of Prohexadione-calcium on Grape Vegetative and Reproductive Development and Wine Chemistry
… stages 21 and 23 decreased Cabernet Sauvignon fruit set whereas application at E-L stages 26, 27, and 29 reduced berry weight without impacting fruit set. Berry weight reduction correlated to higher color intensity (420+520 nm), anthocyanins, total phenols and phenol-free glycosyl-glucose …

Pollination systems in Namaqualand : a response to a predictable winter rainfall regime
… on finding evidence for a reduction in fruit set resulting from pollen limitation. By furthering our knowledge in this aspect of the ecological functioning of Namaqualand, we might be able to better understand and explain the observed pollination syndromes.

Sensor based determination of the fruit bearing capacity in Malus x domestica (Borkh.) aimed at precise crop load management
One major goal of commercial fruit production is a homogenous fruit quality throughout the whole orchard. For this purpose, crop load management practices in apples intend to reduce the number of fruit per tree in order to (i) optimise the carbon supply to demand balance and the (ii) fruit quality …

Ecology of flowering and fruiting in Lotus corniculatus L.
… factors which are important to flowering and fruiting in the species, and some of their evolutionary implications. The work was carried out at Wytham Estate, Oxfordshire, U.K., mainly in an ex-arable field (Upper Seeds) and a more established grassland (Lower Seeds Reserve). The literature on …

Pollination Biology of Gentianales in a Southern Ecuadorian Montane Forest
… presented to nocturnal pollinators had a low fruit set (14%) but a high seed set (59%). Flowers accessible only to diurnal floral visitors showed a high fruit set of 63%, but a low seed set of 14%. Efficiency of pollination (fruit set X seed set) was equal for both diurnal and nocturnal …

Pollination Limitation to Reproductive Success in the Missouri Evening Primrose, Oenothera Macrocarpa (Onagraceae)
… populations increasing from 24.3% to 44.8%. Seed set (proportion of ovules that set seed) increased following supplementation with the mean across populations increasing from 14.7% to 27.9%. These increases were statistically significant in two of the three populations. Failure to achieve 100% …

Plant-flower visitor interactions in the Sacred Valley of Peru
… pollen removal ability and contribution to fruit set. This variation was not correlated: hummingbirds were by far the most frequent visitors but removed virtually no pollen and did not contribute to fruit set. Despite the taxonomic diversity of flower visitors, the main pollinators were …

So happy together? : Pollination and reproductive strategy of two sympatric species of Acanthus L. in Kenya
… later during dry season to display higher fruit set. Both species are pollinated by carpenter bees (Xylocopa). There is no indication for a partitioning of pollinators through divergent flower morphology, as the species display highly similar flowers. A. eminens offers greater quantities of …

Population dynamics and reproductive ecology of the gynodioecious prairie species Lobelia spicata Lam. (Campanulaceae)
… marginally significant negative correlation with fruit set in 2008 and a positive correlation with seed number per fruit in 2009, while population density was positively correlated with seed number per fruit in 2008. Size of L. spicata populations may be having an indirect impact on fruit set and …
