Genotypic variation in Actinidia deliciosa fruit size and carbohydrate content
… produce market, more attention is being given to fruit quality traits and consumer satisfaction. Kiwifruit occupies a niche position in the worldwide market, when compared to apples, oranges or bananas. It is a fruit with extraordinarily good nutritional traits, and its benefits to human health …

Influence of photosynthetic inhibitors on peach
… to bearing peach trees in the field to determine fruit thinning activity. Treatments were: single applications of 1000 or 2000 ppm, double applications a week apart of 1000 ppm, or 2000 followed by 1000 ppm. All treatments significantly reduced fruit number. Fruit drop was 73 to 90% on treated …

PARENT SELECTION IN TOMATO BASED ON MORPHO-PHYSIOLOGICAL TRAITS
… yield is significantly correlated with yield and fruit number but not with harvest index, photosynthesis, specific leaf weight, or average fruit size. Among indeterminates, general combining ability for yield is significantly correlated only with yield.</p><p>Regression analysis indicates that …

Marshelder (<i>Iva annua</i> L.) Seed Morphology and Patterns of Domestication in Eastern North America
… sites. Change in marshelder achene (fruit) size over time sheds light on patterns of regional and subregional domestication processes and patterns of diffusion. The hypothesis that marshelder was introduced into the Cumberland Plateau of eastern Kentucky rather than domesticated in …

Object Detection and Size Determination of Pineapple Fruit at a Juicing Factory
… is to develop a method for determining pineapple fruit size from images. This was achieved by first detecting pineapples in each image using Mask Region-based Convolutional Neural Network (Mask R-CNN) and then extracting the pixel diameter and length measurements, and the projected areas, from the …

Primate-Plant Interactions in the Tropical Dry Forests of Northwestern Madagascar: Seed Dispersal and Sensory Ecology of Eulemur fulvus.
Fruiting plants and frugivores are involved in a complex set of interactions. Frugivores rely on fruiting plants as critical food resources, while fruiting plants rely on frugivores for seed dispersal services. Here, I measure the interrelatedness of brown lemurs (Eulemur fulvus) and the endemic …

Seed dispersal in South African trees: with a focus on the megafaunal fruit and their dispersal agents
… fragmentation, and in animal ecology since fruits can be an important dietary item (Wang and Smith, 2002). The majority of trees in the tropics (70 – 90%) and a large proportion of trees in temperate regions (up to 60%) rely on vertebrates for their dispersal (Howe and Smallwood, 1982; …

Carbohydrates in Glycine max (L.) Merr. fruits during early ontogeny
… in the embryos and young developing fruits of 'Essex' soybeans were determined at anthesis and continuing 10 days after flowering (DAF). The embryo was shown to be filled with starch grains which disappeared with development. Digestion of embryo sections with a mixture of α- and …

Precision horticulture: application on apple orchards
… to achieve the production targets in terms of fruit size, number, yield and, in a near future, fruit quality traits. These data will impact not only the pre-harvest but their effect will extend to the post-harvest sector of the fruit chain. Chapter 1 provides an updated overview on precision …

Characterization of malus germplasm and QTL mapping of fruit quality traits
… of selecting cultivars that have positive fruit-quality attributes. Genetic diversity and relatedness was studied in a Malus germplasm collection to characterize 174 accessions of various Malus species and cultivars. This collection was genotyped using 17 robust simple sequence repeats …

The Significance of Inter- and Intraspecific DNA Content Variation in Agriculturally Important Species
… (P = 0.004) between stomatal length and genome size in the pumpkin varieties. Indicating that nucleotypic selection does appear to be involved in determining fruit size. A technique for providing substantial, thick root formation from weedy Amaranthus species was also examined. No changes in …

'Hass' avocado tree water use and the effects of water stress on fruit development
… water use and the effects of water deficits on fruit development were assessed in New Zealand from 2017 to 2019. Avocado tree water use was quantified by sap flow measurement and the soil water balance method at three sites in the main avocado growing regions of the Bay of Plenty, Whangarei, and …

Effect of NPK basal fertilizer, nitrogen top dressing and season on growth and yield of Cucurbita argyrosperma
… its edible shoots, flowers, immature and mature fruits as well as seeds, which provide proteins, vitamins, edible oils and minerals. The objective of this study was to investigate the effect of NPK basal fertilizer, nitrogen top dressing and seasonal variation on the agronomic traits of C. …

Investigation of Regulatory Mechanisms of Chemical-Mediated Fruit Thinning in Apple (Malus X Domestica Borkh.)
Fruit thinning is critical to the success of apple industry because most apple trees are prone to biennial bearing characterized by heavy bloom and over-cropping in the "on" year and low or no cropping in the "off" year. Fruit thinning can improve fruit size, increase return bloom, and reduce …

The effect of post-harvest ammonium sulphate application, planting time and sucker size on plant growth and yield of queen pineapple, ananas comosus
… Approximately 20% of the plants do not produce fruit, due to mortality or poor growth. Queen pineapple plantings are currently established from suckers taken from harvested plants. The speed and development of suckers on the mother plant is not rapid enough to be used as planting material at …
