SEVERA, L.: Shape and strength of Red Haven peaches at the diff erent stages of their maturity. Acta univ. agric. et silvic. Mendel. Brun., 2008, LVI, No. 4, pp. 161–168 Global shape of the peaches of the Red Haven variety (harvested on diff erent days during July, 2007) has been characterized by calculating the H/Ds, H/Dc and Dc/Ds ratios. There is no, or nearly no, differences between peaches harvested at the diff erent days. The shape of the all tested peaches was very close to round one. The more detailed description of the peach shape is based on the Elliptic Fourier analysis (EFDs) of the digital photos. The knowledge of the parameters (curvature etc.) is very useful e.g. for the evaluation of the results of the strength tests. Compression tests have been also perforemd – the whole peaches have been compressed between two plates at the constant cross–head velocity 20 mm/min. The force–displacement curves are characterised by certain monotonic increase and the point called bioyield, where force exhibits a drop. The bioyield signifi cantly decreases with the date of the harvesting. There is no evidence of the dependence of this parameter on the direction of loading. The same result is approximatively valid for apparent modulus of elasticity E. The force–displacement curves have been successfully modelled by non-linear mathematical models. peach, strength properties, shape analysis, maturity The quality of peaches at consumption depends highly on maturity and ripeness at harvest. There are three stages of peach fruit development. Following bloom, Stage I is a period of cell division and rapid fruit growth, during which the endocarp accounts for most of the size increase (Ryugo, 1988). Stage I ceases about 50 to 60 days a er bloom. Stage II, which can last for varying lengths of time, is marked by pit hardening and slow fruit growth, whereas rapid growth until harvest occurs in Stage III. Fruit growth during the fi nal period is through enlargement of the mesocarp cells (Ryugo, 1988). Stage III usually lasts approximately six weeks see Fig. 1. 1: Schematic of the fruit growth curves (redesigned picture from Jackson, 1975)
