Environmental cues, especially temperature and light, have huge impacts on organ abscission. It has been reported in various plant species that high temperature accelerates reproductive organ abscission. In cotton, day temperatures above 40 °C can induce flower abscission. In soybean, flower abscission was found to increase with the elevated temperature treatment in three different soybean varieties, while …

Benefit transfer approaches, SFA, and DEA yield results that can evaluate how well an NTS site is performing and how to improve their functioning, but have associated advantages and disadvantages . Benefit transfer approaches can provide an estimate for ecosystem services value, which can be used in cost-benefit analyses to determine net changes to well-being. …

Assuming all of the roughly 16 000 smallholder farmers currently growing tobacco were to produce an average of 400kg of paprika, for example, this would result in a total yield of just 6 400 tons, equal to less than half of Zimbabwe’s record crop. Although it is not unreasonable to expect this could lead to …

Zimbabwe exports most of her tobacco crop, however, so if global demand for tobacco were to fall in future , the impact on employment would depend on the extent to which commercial farmers were able to switch to other export crops such as roses, paprika, coffee and vegetables which are also highly labor intensive. Many …

The homolog of Arabidopsis TCP4, AqTCP4, was expressed at fairly consistent levels across all stages in the spurred taxa, but showed a substantial increase in expression in A. ecalcarata at DS3 and DS4, while AqTCP5 showed a gradual decrease in expression across all taxa, but a slightly higher level of expression in A. ecalcarata.Aquilegia has …

As more sampling is completed, e.g. baseline surveys and during pilot mining programs, there will be an opportunity to build a database for genetic information that can be linked to specific species. Accomplishing this aim may require a combined approach.Benthic organisms can be classified by size: megafauna , macrofauna , meiofauna , and microbial communities. …

Assessing the central nutritional role of indigenous agriculture alongside that of hunting and gathering might well suggest that malnutrition, rather than simply the spread of diseases through concentrated settlement, made communities less likely to recover from infectious epidemics. According to Snow, had “European expansion been less rapid, and had lethal epidemics not swept the landscape …

Soil pathogen control with 1,3-D followed by metam sodium and 1,3-D with intermittent water seals was inconsistent between the two experiments, which suggests that specific micro- and macro-level differences in environmental and field conditions may contribute to greater treatment variability and risk to growers.When 1,3-D was sealed with HDPE and VIF, broad leaf weed density was …

Jasmonic acid and ET are known to be involved in defense responses against necrotrophs, such as mediating the host’s responses against them, but ET is also required for fruit ripening and senescence processes, which are conducive to disease susceptibility. Jasmonic acid can also mediate the disease resistance of fruit by increasing the fruit antioxidant capacity, …

Recent years have seen rapid growth in the number of published studies, increased numbers of scientific conferences and development of legal framework and legislation. These trends will inevitably improve the image of this industry and the efficacy of products. Two significant problems still exist within the industry broadly: preparations of products with highly complex multi-component and incompletely identified composition make …
