In the pineapple sector of Benin, poor fruit quality prevents pineapple producers to enter the European market. We investigated effects of common cultural practices, flowering and maturity synchronisation, (1) to quantify the trade-offs of flowering and maturity synchronisation for pineapple quality and the proportion of fruits exportable to European markets, and (2) to determine the effect of ...

Intensive size-selective harvesting can drive evolution of sexual maturity at smaller body size. Conversely, prehistoric, low-intensity subsistence harvesting is not considered an effective agent of size-selective evolution. Uniting archaeological, palaeontological and contemporary material, we show that size at sexual maturity in the edible conch Strombus pugilis declined significantly from pr...

Hyperspectral imaging can help blueberry growers by detecting berries of various maturity stages, so that they can deploy harvesting labors more efficiently. Spectral-spatial detection from hyperspectral images using selected bands is applied to the blueberry maturity stage detection. Nested clustering technique and morphological operations are used as two approaches to spatially process the hy...

the physical and physiological characteristics of sarawak pineapple were studied at five different stages of growth from one to five months after anthesis. changes in fruit length, diameter, pulp color, pulp firmness, ph, total soluble solids, titratable acidity, ascorbic acid content and antioxidant activity were monitored. the sarawak pineapple exhibited a sigmoid growth pattern during fruit ...

Understanding the consequences of environmental change on ecological and evolutionary dynamics is inherently problematic because of the complex interplay between them. Using invertebrates in microcosms, we characterise phenotypic, population and evolutionary dynamics before, during and after exposure to a novel environment and harvesting over 20 generations. We demonstrate an evolved change in ...

This study was carried out to determine the effects of Lactobacillus plantarum on chemical compositionand nutritive value of whole-plant corn (WPC) ensiled at different stages of maturity. Based on local routinepractice, WPC was harvested at three stages of maturity as follows: (1) two weeks before routine harvestingtime; (2), one week before routine harvesting time and (3), routine harvesting ...

Abstract The aim of this research is to present a simulation model for reducing economic damages of mechanized wheat harvesting in the weather conditions of Khuzestan province and similar areas. The simulated model is composed of three sub-models, for determining of the appropriate working hours, grain losses, and economic sub-model. In order to determine the appropriate working hours, a mathem...
