In order to set up large-scale acclimatization protocols of micropropagated plants, an in-depth knowledge of their physiological responses during in vitro to ex vitro transfer is required. This work describes the photosynthetic performance of Ulmus minor micropropagated plants during acclimatization at high irradiance (HI; 200 ± 20 μmol m−2 s−1 or low(More)
Extreme conditions, such as drought, high temperature, and solar irradiance intensity, are major factors limiting growth and productivity of grapevines. In a field experiment, kaolin particle film application on grapevine leaves was examined during two different summer conditions (in 2012 and 2013) with the aim to evaluate benefits of this practice against(More)
This paper presents a computer program written in BASIC for fitting different enzyme inhibition kinetic models. The program, based on a nonlinear least-squares regression, can be run on any microcomputer with the CP/M operating system. Weighting of observed initial velocities is decided by the user by assessing constant variance, proportional variance or by(More)
This study aimed to investigate the effects of irradiance on plant growth and content of proline and phytohormones during ex vitro acclimatization of micropropagated Ulmus minor plants. In vitro rooted plants were acclimatized to ex vitro conditions in a climate chamber with two irradiances, 200 μmol m−2 s−1 (high irradiance, HI) and 100 μmol m−2 s−1 (low(More)
This paper presents a program written in the BASIC language for the Radio Shack TRS-80 PC-1 or the Sharp PC 1211 pocket computers for fitting the Hill equation to experimental data. The program is based on a procedure involving a combination of an optimization technique and non-linear regression. The program determines precisely all three parameters of the(More)
Drought is often an important constraint on plant regeneration in the Mediterranean. Pistacia lentiscus is of particular interest in restoration actions in fire-prone areas. This study addressed the current knowledge gap on the physiological response of this species to drought during its initial development. We hypothesized that the seedlings would have a(More)
This paper presents a program written for the Radio Shack TRS-80 or the Sharp PC 1211 pocket computers for fitting the Michaelis-Menten equation to experimental data by a non-linear regression analysis. The program determines the kinetic parameters Km and Vm, their standard errors and the residual standard error. In addition it performs a simulation of a(More)
A screening method for the characterization and differentiation of proteinaceous samples and amino acid mixtures was applied to protein foods (4 protein-rich mixtures, one product sold as dietary supplement, and 3 raw materials of frequent use in the preparation of these products). Graphic profiles which describe the relative amounts of amino acid groups in(More)
Over the period from January 1980 to March 1988 the frequency of dysplastic abnormalities associated wits 202 apparently benign gastric ulcers was determined and their course monitored. The relevant data were then evaluated separately for the various subgroups the ulcers were divided into on the basis of their natural history. No correlation was detected(More)
The authors examine the clinical evolution of a patient with an oesophageal neoplasm with intraperitoneal liver metastases unnoticed in preoperative phase. Some months after the explorative operation, the patient first underwent a thoracotomy + a cervicostomy with monopolar exclusion of oesophagus because of a mediastinitis caused by a iatrogenic(More)
