TLDR
Application of synthetic auxins formulations increased fruit size, but had detrimental effects on fruit quality at harvest and during storage, or on return yield in the following year.Abstract:
SummaryThe only commercial apricot cultivar grown in Israel, ‘Canino’, produces relatively small fruit. Over three consecutive years (2003–2005), application of 25 – 50 mg l–1 2,4-dichlorophenoxypropionic acid [2,4-DP; as its butoxyethyl ester (PowerTM)], 15 mg l–1 3,5,6-trichloro-2-pyridyloxyacetic acid [3,5,6-TPA; as the free acid (Maxim®)], or 25 – 40 mg l–1 2,4-dichlorophenoxyacetic acid (2,4-D) plus 30-50 mg l–1 naphthaleneacetic acid (NAA; 0.3% – 0.5% AmigoTM), at the beginning of pit-hardening, when the widest diameter of the fruit was 25 mm, caused appreciable and significant increases in fruit size and total yield. Anatomical studies revealed that the main effect of these synthetic auxins was via direct stimulation of fruit cell enlargement. None of the above auxins had any negative effect on fruit quality, either at harvest or after 1 month of storage at 0°C, or on return yield in the following year. Two other synthetic auxins formulations: 2,4-D (HadranolTM) and 2,4-dichlorophenoxypropionic aci...read more

TL;DR: A mechanical device is used to measure the physical pressure required to break the olive pit in order to define the timing of pit hardening more precisely and to permit closer observation of its relationship to fruit and endocarp growth and development.

GA3 inhibits flowering, reduces hand-thinning, and increases fruit size in peach and nectarine

TL;DR: Application of 25 mg l−1 GA3 to the basal part of shoots during flower bud induction (60 d after full bloom ) reduced flowering of ‘Snow-Queen’, ‘Queen-Giant’ and ‘Arctic Mist’ nectarines, and ’Scarlet-Snow’ peach in the following season and the time spent on hand-thinning was reduced, and the yields of large fruit increased approx two-to-three fold.

Auxin (triclopyr) and cytokinin (forchlorfenuron) differentially affect fruit physiological, organoleptic and phytochemical properties of two apricot cultivars
Peter A. Roussos,Efstathios Ntanos,Nikoleta-Kleio Denaxa,Athanassios Tsafouros,Intidhar Bouali,V. Nikolakakos,Anna Assimakopoulou +6 more
TL;DR: The present findings support the use of auxin as the PGR of choice for stone fruits and especially for apricot, while cytokinin do not seem to be able to improve fruit quality characteristics.
