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]
Influence of Irrigation Method and Fertilization Type on Avocado Yield and Quality
This research study investigated the impact of watering method and fertilization on avocado yield and quality in newly reclaimed areas. The research attempted to choose the optimum irrigation system and fertilization type to improve avocado yield and quality. Different irrigation systems (micro-sprinkler, drip irrigation and combined approach of micro-sprinkler and drip) with different fertilization types (mineral fertilization, fertilization using fallen avocado leaves+mineral fertilization and
Water management and salinity adaptation approaches of Avocado trees: A review for hot-summer Mediterranean climate
The production and consumption of avocado has increased significantly over the past years, experiencing a steady expansion into new markets around the world. This review paper focuses on avocado cultivation in its new markets with hot-summer Mediterranean climate. A significant literature gap exists on the viability of this crop in such data environments which experience limited availability of water in the summer exacerbated by climate change and potential salinity issues in irrigation water, typical
Rootstock-Dependent Response of Hass Avocado to Salt Stress
Salt stress is a major limiting factor in avocado (Persea americana) cultivation, exacerbated by global trends towards scarcity of high-quality water for irrigation. Israeli avocado orchards have been irrigated with relatively high-salinity recycled municipal wastewater for over three decades, over which time rootstocks were selected for salt-tolerance. This study's objective was to evaluate the physiological salt response of avocado as a function of the rootstock. We irrigated fruit-bearing 'Hass'
Water use of an intermediate and a mature avocado orchard
The scarce water resources in South Africa are vulnerable to the increasing pressure of a changing climate. The recent drought experienced in South Africa (2014-2017) has negatively affected the fruit industry, highlighting the need to optimise water use efficiency (WUE) as well as accurately estimate water use. With avocado production in South Africa being export-oriented and dependant on irrigation, proper water management is vital to minimising water use, while maintaining fruit yield and quality.
Physiological and Molecular Responses of ‘Dusa’ Avocado Rootstock to Water Stress: Insights for Drought Adaptation
Avocado consumption is increasing year by year, and its cultivation has spread to many countries with low water availability, which threatens the sustainability and profitability of avocado orchards. However, to date, there is not much information on the behavior of commercial avocado rootstocks against drought. The aim of this research was to evaluate the physiological and molecular responses of ‘Dusa’ avocado rootstock to different levels of water stress. Plants were deficit irrigated until
