In this article we describe a practical planning problem, the potted plant packing problem, and our first approaches to solve this problem. The transportation of plants is comparably expensive as they require careful treatment due to there sensitivity. For standardised transport, potted plants are loaded on transport trollies. The cost of transportation depends on the number of these trollies. ...

A filter paper bioassay was developed for testing the efficacy of nematodes and other agents for control of Diaprepes abbreviatus larvae. Surfactants, with and without Steinernema riobravis, were screened first in the filter paper bioassay and then in a potted citrus seedling study. The results of the two assays were in agreement on the relative merits of the compounds tested. Surfactants incre...

High biodiversity is known to increase many ecosystem functions, but studies investigating biodiversity effects have more rarely looked at multi-trophic interactions. We studied a tri-trophic system composed of Centaurea jacea (brown knapweed), its flower head-infesting tephritid fruit flies and their hymenopteran parasitoids, in a grassland biodiversity experiment. We aimed to disentangle the ...

effects of fe and trichoderma harzianum bi strain on plant growth and development of spathiphyllum were investigated. experiments were carried out in an glasshouse and in pots filled with soil, perlite and coco peat (1:1:1) were used as the growing medium. plant roots (seedlings with three leaves) were inoculated with trichoderma (0 and 8% w/w) as media mixture. fe spray (0, 0.75, 1.5, 3 g/l), ...

Physical disturbance of plants or plant parts results in a mechanical stress response from the plant. Mechanical stress applied naturally or under controlled conditions inhibits growth in mass and dimensions of major plant parts. Wind and precipitation are important natural sources of mechanical stress. Under field conditions, cultivated plants experience these natural mechanical stresses plus ...

The name Primula or primrose is derived from the word primary or first, referring to the early growth and flowering in spring (Liberty Hyde Bailey Hortorium, 1976). More than 400 species of primula exist in the family Primulaceae (Griffiths, 1994). Other important horticultural genera in this family, besides primula, include pimpernel (Anagallis), rock jasmine (Androsace), persian violet, alpin...

As a popular ornamental flower, potted lily is an important object of lily breeding. Paclobutrazol, a chemical growth retardation compound, is often used to dwarf plant in producing potted lilies. However, in recent years, the plants with inherited dwarf traits by using genetic engineer breeding technology are being developed. The studies on molecular basis of lily dwarfism will offer some targ...

We examined the effects of fertilization on population abundance and within-plant distribution of western flower thrips, Frankliniella occidentalis Pergande (Thysanoptera: Thripidae), on potted chrysanthemum, Dendranthema grandiflora (Tzvelev). We also investigated the effects of fertilization on the number of insecticide applications needed to control F. occidentalis on potted chrysanthemum. U...

BACKGROUND AND AIMS Extreme water stress episodes induce tree mortality, but the physiological mechanisms causing tree death are still poorly understood. This study tests the hypothesis that a potted tree's ability to survive extreme monotonic water stress is determined by the cavitation resistance of its xylem tissue. METHODS Two species were selected with contrasting cavitation resistance (...
