Water stress affects leaf anatomy, gas exchange, water relations and growth of two avocado cultivars
Two cultivars of avocado (Persea americana Mill., 'Fuerte' and 'Hass') plants, grown in 501 containers, were studied under two irrigation regimes for 6 months in order to evaluate the growth response and leaf physiological and anatomical changes induced by moderate water stress. Irrigation was applied when soil water potential reached at -0.03 and -0.5 MPa for the wet and dry treatments, respectively. Leaf anatomy changed in water-stressed leaves, which could have accounted for the decreased stomata]
Long term changes in soil properties and enzyme activities after almond shell mulching in avocado organic production
The recycling of almond shell as mulch would allow avocado orchards to be managed organically, maintaining plant yield and improving soil conditions simultaneously. This study aims to analyze the long term effects of successive applications of almond shell as mulching for organically grown avocado. Effects on soil properties, enzyme activities and soil carbon storage as well as avocado yield and growth were studied in comparison to no-tillage conventionally managed (using mineral fertilizers and
