growth traits, yield and fruit quality in ‘synda’ tomato were compared with those in tomatoes grafted onto either ‘king kong’ rootstock or onto their own rootstocks, (trained as single or double stem), and at two fruit thinning levels, of: no thinning or thinned to five fruits per truss. the data related to crop growth rate (cgr), relative growth rate (rgr), net assimilation rate (nar), leaf ar...

A cDNA clone encoding a putative dihydroflavonol 4-reductase gene has been isolated from a strawberry (Fragaria x ananassa cv Chandler) DNA subtractive library. Northern analysis showed that the corresponding gene is predominantly expressed in fruit, where it is first detected during elongation (green stages) and then declines and sharply increases when the initial fruit ripening events occur, ...

This paper presents a computer vision based system for automatic detection and sorting of fruits. Detection is important because it is fully automated system, sometimes input to system may be other than fruit which is having same color and size as that of particular fruit. In this work we are capturing two images to make our system more accurate and cover maximum area of fruit. Image analysis i...

In 2007 to 2008, a fruit rot of Melon (Cucumis melo L.) caused by Sclerotium rolfsii occurred sporadically in a farmer's vinyl house in Jinju City. The symptoms started with watersoaking lesion and progressed into the rotting of the surface of fruit. White mycelial mats appeared on the lesion at the surface of the fruit and a number of sclerotia formed on the fruit near the soil line. The scler...

Seeking to accurately detect and localize fruit of any color in 3D space for selective agrobotical operations, we exploit data given by Time-of-Flight or RGB-D cameras and propose a novel shape-based fruit detector using a fruit pose reference frame relative to the viewer. Surface normals, which are shaped-based local features, are accumulated into bins of different shapes along the reference f...

Strawberry is rich in anthocyanins, which are responsible for the red color, and contains several colorless phenolic compounds. Among the colorless phenolic compounds, some, such as hydroxycinammic acid derivatives, emit blue-green fluorescence when excited with ultraviolet (UV) light. Here, we investigated the effectiveness of image analyses for estimating the levels of anthocyanins and UV-exc...

Investigations have been carried out in recent years in an effort to improve the color of various fruits. Citrus and other semitropical fruits, in particular, have received the most attention. Several studies of the factors influencing the formation of the red pigment of apples have been made. In general, such studies have included the influence of light, fertilization, pruning, and artificial ...

In some primate lineages, polymorphisms in the X-linked M/LWS opsin gene have produced intraspecific variation in color vision. In these species, heterozygous females exhibit trichromacy, while males and homozygous females exhibit dichromacy. The evolutionary persistence of these polymorphisms suggests that balancing selection maintains color vision variation, possibly through a 'trichromat adv...

Intraspecific color vision variation is prevalent among nearly all diurnal monkeys in the neotropics and is seemingly a textbook case of balancing selection acting to maintain genetic polymorphism. Clear foraging advantages to monkeys with trichromatic vision over those with dichromatic "red-green colorblind" vision have been observed in captive studies; however, evidence of trichromatic advant...
