This presentation focuses primarily on recent developments in new technologies that have impacts on decay control. These technologies include 1-methylcyclopropene (1-MCP) and new preand postharvest fungicides. With the increasing use of 1-MCP in the apple industry, depending on varieties, many apples do not have to be drenched with diphenylamine (DPA) prior to storage. Because use of 1-MCP has ...

Here we introduce a class of linear operators called recursive orthogonal transforms (ROTs) that allow a natural implementation on a distributed control network. We derive conditions under which ROTs can be used to represent SO(n) for n¿4. We propose a paradigm for distributed feedback control based on plant matrix diagonalization. To nd an ROT suitable for this task, we derive a gradient ow on...

Considerable economic losses to harvested fruits are caused by postharvest fungal decay during transportation and storage, which can be significantly controlled by synthetic fungicides. However, considering public concern over pesticide residues in food and the environment, there is a need for safer alternatives for the control of postharvest decay to substitute synthetic fungicides. As the sec...

The modular design of plants enables individual plant organs to manifest autonomous functions and continue aspects of metabolism, such as respiration, even after separation from the parent plant. Therefore, we hypothesized that harvested vegetables and fruits may retain capacity to perceive and respond to external stimuli. For example, the fitness advantage of plant circadian clock function is ...

For three Asiatic hybrid lily cultivars (‘Bright Beauty’, ‘Fashion’, ‘Orlito’) the potential postharvest performance of floral buds in terms of growth, anthesis and longevity was studied in relation to tepal carbohydrate status. To determine the importance of carbohydrate redistribution within lily inflorescences, the postharvest performance of several attached and detached buds was compared at...

Certain nematicidal treatments for the control of root knot of tobacco in six field experiments in North Carolina were used to determine early, midseason, and postharvest densities of eggs and larvae of Meloidogyne spp., postharvest root-knot indices, and crop yield and value. Various statistical correlations showed that population densities determined 6-8 wk after transplanting were more indic...

Abstract Avocado sunblotch viroid (ASBVd) is found in many avocado-growing regions of the world, where it affects fruit yield and quality. The trees develop two types infections: symptomatic symptomless infections. Symptoms are most obvious as yellow streaks on leaves, green stems carrier do not display any such symptoms. Symptomless considered primary source disease transmission orchards. Henc...

BACKGROUND AND OBJECTIVES The bio-conversion of plant lignocellulose to glucose is an key component of second generation biofuel production, but the resistance of lignin to breakdown is a major obstacle in this process. Filamentous fungi possess the unique ability to decompose the aromatic lignin polymers using enzymes encoded by divergent gene families. White-rot fungi are the primary lignin-d...

The use of chemicals in postharvest technology of horticultural crops is highly restricted and it is necessary to introduce safe food preserving methods. Strawberry is very susceptible to postharvest losses and more than 50% of harvested fruit is lost in Iran. Effect of postharvest treatment with methyl jasmonate (at 0, 8, and 16 μmol L(-1)) on some quality attributes of Sabrosa strawberry frui...
