TLDR
This study is the first to demonstrate an increase in fruit abscission in an evergreen tree in response to pruning, and appeared to be related to competition for carbohydrates between post-pruning shoot growth and fruit development and was local.About:

The reproductive biology of macadamia
TL;DR: This review summarises over 75 years of research on floral induction, floral structure, pollen transfer, the breeding system and fruit development of macadamia, highlighting features such as insect pollination and partial self-incompatibility that limit orchard productivity and affect kernel quality.

PARTITIONING OF PHOTOASSIMILATES IN AVOCADO (Persea americana Mill) DURING FLOWERING AND FRUIT SET
TL;DR: In this paper, the distribution of recent photoassimilates was examined before and during flowering, fruit set, and the transition from sink to source of developing vegetative shoots in avocado (Persea americana mill).
Journal ArticleDOI
Sugar Metabolism in Stone Fruit: Source-Sink Relationships and Environmental and Agronomical Effects
Rachele Falchi,Claudio Bonghi,María F. Drincovich,Franco Famiani,María V. Lara,Robert P. Walker,Giannina Vizzotto +6 more
TL;DR: In stone fruit trees, the presence of an elevated number of fruits alters the source-sink balance, with a consequent intensification of competition among them and between vegetative and reproductive growth, and the main environmental factors affecting this balance and the agronomical/artificial manipulations of source-Sink relationships are reviewed.
Journal ArticleDOI
Pollination of macadamia: Review and opportunities for improving yields
TL;DR: This review aims to collate what is currently known about the pollination of macadamia varieties, assess the factors that may hinder effectivepollination and subsequent yield, and identify opportunities to improve both pollination and yield in commercial Macadamia orchards.
Journal ArticleDOI
Time of pruning affects fruit abscission, stem carbohydrates and yield of macadamia.
TL;DR: Hedging time changed the pattern of fluctuations in stem water-soluble carbohydrates (WSC).

Tansley Review No. 27 The control of carbon partitioning in plants
TL;DR: There is a need for a greater understanding of organ initiation and development, the clear identification of whether growth is sink or source limited, and a detailed assessment of the role of storage in buffering developmental and environmental changes in sink and source activity.
Journal ArticleDOI
The theory and practice of branch autonomy
TL;DR: The past 15 years have seen a surge of interest in modularity in plants, in the implications of the fact that plants are composed of repetitive modules that may in some ways behave as in independent units.
Journal ArticleDOI
PEACH: A simulation model of reproductive and vegetative growth in peach trees.
TL;DR: The fit between model predictions and field data supports the initial hypothesis that plants function as collections of semiautonomous, interacting organs that compete for resources based on their growth potentials.
Journal ArticleDOI
Hormonal regulation of fruitlet abscission induced by carbohydrate shortage in citrus.
TL;DR: ABA and ACC are identified as components of the self-regulatory mechanism that adjusts fruit load to carbon supply, and offers a physiological basis for the photoassimilate competition-induced abscission occurring under natural conditions.
Journal ArticleDOI
Defoliation increases fruit abscission and reduces carbohydrate levels in developing fruits and woody tissues of Citrus unshiu
TL;DR: It is suggested that developing fruitlets are utilization sinks during the cell division period and act as storage sinks duringThe cell enlargement stage, compatible with the proposal that sucrose supply is a major factor of the regulatory mechanism for citrus fruit abscission during the June drop.
