NSF-funded scientists at Cold Spring Harbor Laboratory are figuring out how to pack more kernels onto a corn cob. One way to boost the productivity of a plant, they say, is to redirect some of its res...
The biological control of angular leaf spot disease (ALS) of cucumbers (Cucumis sativus), caused by Pseudomonas syringae pv. lachrymans (Psl), using promising rhizobacteria (RB) and to compare RB eff...
Woody vegetation, such as trees and shrubs, has increased dramatically in Ozark grasslands over the past 75 years, according to a study published this week in the journal Landscape Ecology.The study e...
Background: The thermogenic effects of green tea catechin have been repeatedly reported, but their mechanisms are poorly understood.
The effect of different concentrations of brassinosteroids (1:10, 1:100, 1:210) on the germination of sycamore (Acer pseudoplatanus L.) and ash (Fraxinus excelsior L.) seeds was investigated in stre...
The aim of the research is to increase the lifetime of a mould board by means of a constructional setting of an overlaid material. The lifetime increasing of the ploughshare by means of the overla...
The aim of this paper was to analyse alternatives of Pinzgau breeding program. Alternatives were optimised for genetic gain of selection index composed of parameters of milk efficiency traits and incr...
Clearcuts are one of the results of forest management. The aim of this study was to assess the effect of clearcuts on bird communities in a managed forest in Western Poland. I applied the method of po...
A deterministic simulation was conducted to assess the effects of sexed semen utilization strategies on age at first calving (AFC). Four different strategies were implemented on dairy heifers: continu...
Pasture-based automatic milking systems (AMS) require cow traffic to enable cows to be milked. The interval between milkings can be manipulated by strategically allocating pasture. The current experim...
Our previous results showed that kisspeptin-10 (Kp-10) injections via intraperitoneal (i.p.) once daily for three weeks notably promoted the egg laying rate in quails. In order to investigate the mech...
Down logs provide important ecosystem services in forests and affect surface fuel loads and fire behavior. Amounts and kinds of logs are influenced by factors such as forest type, disturbance regime, ...
Sugar beet is the main crop commonly cultivated for sugar production in temperate regions of the World. Actual yields in main Central Europe producing countries are much lower, due to many limiting fa...
The use of chemical inducers for the development of host resistance is an alternative approach to plant disease management and is assumed to be much more environmentally sound than traditional pestici...
Weed management is the most important limiting factor in butternut production by smallholder irrigation farmers in South Africa. Post-emergence chemical weed control options for butternut farms are ve...
