The materials of the article present data on various manifestations ability repeated flowering and fruiting during one growing season by representatives subgenus Eubatus Focke (blackberry). research was carried out in experimental plantings Russian Research Institute Fruit Crop Breeding (city Orel). Classical methods cultivar study were used. Experimental blackberry cultivars have different mat...
The development of models to predict yield potential and quality of a Miscanthus crop must consider climatic limitations and the duration of growing season. As a biomass crop, yield and quality are impacted by the timing of plant developmental transitions such as flowering and senescence. Growth models are available for the commercially grown clone Miscanthus x giganteus (Mxg), but breeding pro...
Frost exposure is a particular challenge for cultivating perennial crops, whose adaptive capacity to weather and climate impacts limited. Irrigation common means of mitigating damage, but draws on limited water resources, costly, energy intensive. Here we examined the projected impact change incidence frost temperatures during coldest winters, defined by 98th percentile cool season (November–Ap...
Bioenergy sorghum is targeted for production in water-limited annual cropland therefore traits that improve plant water capture, water use efficiency, and resilience to water deficit are necessary to maximize productivity. A crop modeling framework, APSIM, was adapted to predict the growth and biomass yield of energy sorghum and to identify potentially useful traits for crop improvement. APSIM ...
In New Zealand, increasing levels of resistance in diamondback moth (DBM) to recommended synthetic pyrethroid and organophosphate insecticides were monitored for five years in vegetable Brassica crops until in 1997 they were associated with control failures in three regions. Subsequently, Crop & Food Research initiated a two-year IPM implementation programme with financial assistance from gover...
Replacement of diseased plants with healthy plants is commonly used to manage spread of plant pathogens in perennial cropping systems. This strategy has two potential benefits. First, removing infected plants may slow pathogen spread by eliminating inoculum sources. Second, replacing infected plants with uninfected plants may offset yield losses due to disease. The extent to which these benefit...
[1] Old-field succession is a widespread process active in shaping landscapes in the eastern United States, contributing significantly to the terrestrial sink of atmospheric carbon dioxide, particularly at midlatitudes. However, few studies document ecosystemscale carbon dioxide exchange during the early years of old-field succession, particularly during the temporal transition from cultivation...
