This collection features five peer-reviewed reviews on optimising
rootstock health. The first chapter explores optimising rootstock
health to improve root function, resource-use efficiency,
sustainability and agricultural productivity. The chapter also
presents a case study on tomato rootstocks as a viable strategy to
overcome abiotic stresses in Ghana. The second chapter reviews the
important aspects of tree growth and development in apple
production which are integral to ensure product quality. The
chapter discusses the importance of rootstocks and emphasises the
mechanisms and morphological effects of dwarfing on rootstocks. The
third chapter considers recent advances in the development and
utilisation of fruit tree rootstocks, focussing primarily on
apples. The chapter also reviews rootstock tolerance to both
abiotic and biotic stresses. The fourth chapter discusses advances
in avocado tissue culture for clonal propagation and highlights the
potential of this technology for improving the sustainable supply
of high-quality avocado plants to support future avocado industry
growth. The final chapter addresses the challenges and
opportunities in pear breeding, focussing on pear cultivars, pear
rootstocks and germplasm resources. The chapter also considers the
use of dwarfing as a means of improving particular traits.
Originating in Central Asia, apples are one of the most important
fruits globally and are grown in over 100 countries. Apple
cultivation faces a number of challenges. Increasing global
competition has put the focus on lowering costs whilst further
improving sensory quality and shelf-life. There is a need to reduce
inputs such as water, fertiliser and labour, both to save costs and
reduce environmentally-damaging emissions and pollution. There is a
continual battle with fungal, viral and bacterial diseases as well
as insect pests. In the long term there is a need for new varieties
able to withstand disease or more extreme conditions associated
with climate change. This means preserving genetic variety and
exploiting new molecular breeding techniques opened up by the
sequencing of the apple genome in 2010. Drawing on an international
range of expertise, this collection focuses on ways of improving
the cultivation of apples as a food crop at each step in the value
chain, from breeding through to post-harvest storage. The book
first reviews research in apple physiology and breeding. The
following sections focus on cultivation techniques through to
post-harvest storage, followed by a discussion of diseases and
pests and their management. Concluding chapters address wider
issues such as economics, consumer trends and sustainability.
Achieving sustainable cultivation of apples will be a standard
reference for fruit and horticultural scientists in universities,
government and other research centres and companies producing
apples.
