Reducing the incidence of calyx cracking in ‘Pink Lady’ apple using a combination of cytokinin (6-benzyladenine) and gibberellins (GA4+7)
TLDR
The results from semi-commercial multiple applications of 0.2% (v/v) Superlon™ supported its use in orchards of ‘Pink Lady’ that tend to suffer from calyx cracking, and increased fruit size, probably due to the effect of BA.Abstract:
SummaryCalyx cracking in ‘Pink Lady’ apple (Malus × domestica Borkh.) results in substantial economic losses. ‘Pink Lady’ apple trees were sprayed with various rates and combinations of synthetic gibberellins (GA3, or GA4 plus GA7) and a synthetic cytokinin (6-benzyladenine; BA) at different phenological stages, starting at 60 d after full bloom (DAFB) until 150 DAFB, to determine if the incidence of cracking could be reduced. The experiments were conducted in Northern Israel between 2008 – 2011. The percentages of fruit with calyx cracking decreased following three applications of 0.2% (v/v) Superlon™ (i.e., 40 mg l–1 BA plus 40 mg l–1 GA4+7) at 14 d intervals, starting at 60 DAFB.GA3 or GA4+7 alone had no effect on cracking. In addition, the Superlon™ treatments resulted in increases in epidermal cell density at the calyx end, which may have contributed to the increased elasticity of the peel, thus preventing crack formation. No change was observed in cuticle thickness. Fruit quality was not affected by...read more

Maintenance of high epidermal cell density and reduced calyx-end cracking in developing ‘Pink Lady’ apples treated with a combination of cytokinin 6-benzyladenine and gibberellins A4+A7
TL;DR: In this article, a histological analysis of the peel at the calyx-end following the application of a mixture of synthetic gibberellins (GA4 plus GA7) and cytokinin (6-benzyladenine; BA) was conducted in Northern Israel during 2011 and 2012.

Strengthening fruit-skin resistance to growth strain by application of plant growth regulators
Idit Ginzberg,Raphael A. Stern +1 more
TL;DR: The skin is proposed to view as a tissue whose characteristics may be manipulated to improve its resistance to environmental and growth strains, and the hypothesis that similar treatments may be applied with various agricultural important fruits is discussed.

TL;DR: Plant hormones are a group of naturally occurring, organic substances which influence physiological processes at low concentrations, mainly of growth, differentiation and development, though other processes, such as stomatal movement, may also be affected.
