On-farm conservation of potato landraces in Ecuador
Álvaro Monteros-Altamirano

Abstract: Potato-landrace production systems have not been previously described in Ecuador. Accordingly, three areas of high potato diversity were identified using the passport data of samples collected during the 70s and 80s. Native potato diversity collected at these

Fertility recovery of anther-derived haploid plants in Cape gooseberry (Physalis peruviana L.)

Abstract: The cape gooseberry (Physalis peruviana L.) is one of the most important Colombian exotic fruits. Chromosome doubling of anther-derived plants is a key factor in the application of double haploid technology for the genetic improvement of crops. In the present

Initial interference of Cyperus rotundus L. in pre-sprouted seedlings of sugarcane cultivars RB985476 and IACSP95-5000

Abstract: Weeds compete with plants for water, light, nutrients and space. In sugarcane, planting pre-sprouted sugarcane seedlings (PSS) may mean a change in weed interference and management. The aim of this study was to generate information on the interference of Cype

Spectral and thermal response of Heliconia psittacorum species to induced water stress

Abstract: An important limitation in agricultural production is stress resulting from water deficit. Flower production and post-harvest life both decrease in Heliconia psittacorum affected by water stress. Remote sensing provides tools for estimating the water status o

Effect of sowing density on yield and profitability of a hybrid corn under tropical conditions

Abstract: A high sowing density in maize is a widely used management practice for increasing crop yield; this method increases intraspecific competition for solar radiation, nutrients and water, so yield per plant is reduced, but a greater number of plants is harvested

Radish (Raphanus sativus L.) morphophysiology under salinity stress and ascorbic acid treatments

Abstract: The use of saline or low-quality water in agriculture is an alternative to increasing water demand, especially in arid or semi-arid regions. However, the use of water with high levels of salts causes disturbances in plants, which can lead to their death; thus

Assessing water demand with remote sensing for two coriander varieties
Euseppe Ortiz Enrique A. Torres

Abstract: The use of remote sensing to determine water needs has been successfully applied by several authors to different crops, maintaining, as an important basis, the relationship between the normalized difference vegetation index (NDVI) and biophysical variables, s
