Automation in cherry harvesting is essential to reduce the demand for seasonal labor for cherry picking and reduce the cost of production. The mechanical shaking of tree branches is one of the widely studied and used techniques for harvesting small tree fruit crops like cherries. To automate the branch shaking operation, different methods of detecting branches and cherries in full foliage canop...
Oil palm (Elaeis guineensis) is the most productive oil bearing crop worldwide. It has three fruit forms, namely dura (thick-shelled), pisifera (shell-less) and tenera (thin-shelled), which are controlled by the SHELL gene. The fruit forms exhibit monogenic co-dominant inheritance, where tenera is a hybrid obtained by crossing maternal dura and paternal pisifera palms. Commercial palm oil produ...
Although the potential of marker-assisted selection (MAS) in fruit tree breeding has been reported, bi-parental QTL mapping before MAS has hindered the introduction of MAS to fruit tree breeding programs. Genome-wide association studies (GWAS) are an alternative to bi-parental QTL mapping in long-lived perennials. Selection based on genomic predictions of breeding values (genomic selection: GS)...
generally, fruit trees should produce sufficient yield annually through their economic life. fruit trees usually produce flowers over their ability of productivity. if all of the flowers are converted to fruit, the tree will be weak and poor smaller fruit will be produced and it may cause alternate bearing. thus some flowers must be removed by hand, mechanically or chemically. in this study, th...
abstract: olives belong to the family of olea europaea l. is a popular fruit tree. the fruit and the oil extracted from it is consumed worldwide particularly in the mediterranean regions. in this study changes in the fatty acid composition of the oil extracted from olive fruit during the course of maturation is investigated. this work is concerned with the best harvesting point when oleic acid ...
Pomegranate fruit from the tree Punica granatum has been dubbed as the "nature's power fruit." Dating back to Biblical times, the tree itself is attributed to possess extraordinary medicinal properties. The geographical distribution of the tree, being native to the Middle East and some Asian countries, is generally attributed to a lack of interest in its medicinal properties by many western sci...
INTRODUCTION Artocarpus lakoocha Roxb., Moraceae, is a valuable tropical tree species native to India and used for fruit, furniture, timber, and feed. The lakoocha fruits are generally eaten fresh. Each fruit contains 20–30 seeds that are fleshy with thin seed coat. The edible fruit pulp is believed to act as a tonic for the liver. Raw fruits and male flower spike (acidic and astringent) are ut...
The application of pesticides to fruit throughout the Northeastern US, as in the rest of the world, gives rise to concern, primarily due to inaccurate application, which often results in high residues and environmental pollution. Inaccuracy, due to overor under-application, may result in high levels of disease or insect activity. Air and water pollution resulting from pesticide drift is a major...
The labor-intensive nature of harvest in the tree fruit industry makes it particularly sensitive to labor shortages. Technological innovation is thus critical in order to meet current demands without significantly increasing prices. This paper introduces a robotic system to help human workers during fruit harvest. A second-generation prototype is currently being built and simulation results dem...
Models are used extensively in research, in the social sciences [e.g. economics] as well as in the physical, chemical and biological sciences. As a preliminary definition one could think of a model as an attempt to describe a certain process or system through the use of a simplified representation, preferably a quantitative mathematical expression, that focuses on a relatively few key variables...
