Enhancing the Natural Disease Resistance of Potatoes
In order to reduce pollution and strive for a cleaner environment, significant efforts are being made to develop alternatives to synthetic pesticides for the control of plant diseases. A promising alternative is to stimulate the natural resistance of plants. Recent advances in our understanding of the mechanisms of the expression of plant defense mechanisms when attacked by disease causing path...
متن کاملNitrogen Requirements of Potatoes
Nitrogen fertilizer applications, for maximum fertilizer efficiencies and crop yields, should be based on the N required by the crop during its various growth stages. The objectives of this paper were to identify the N requirements of the potato plant (Solarium tuberosurn L.) during growth and to evaluate selected soil and plant tissue tests as indicators of the plant's N status. Growth analysi...

Already AF is the most common sustained arrhythmia worldwide; in the US alone the estimated prevalence in 2010 was between 2.7 to 6.1 million, and this is expected to rise to between 5.6 and 12 million by 2050 [1]. The source of this increase is multifactorial and our current ability to manage the condition is often subop...
متن کاملThe Ecogeography of Andean Potatoes
Adaptation to varied habitats confers ecological versatility and the capacity for coarse-grained distribution across heterogeneous habitats, whereas ecological specialization implies a restricted pattern. Ecogeography and adaptive trairs help to determine whether farmers are able to adjust their diverse erops to socioeeonomie and environmental changes (a process known as in situ conservation) o...
