Predicting individual phenological phases in peaches using meteorological data

The submitted work deals with the relation between the sum of active temperatures above 7°C and important phenological phases in peach tree cultivation. The aim of the paper is to provide information for growers, especially regarding anticipated harvest dates, which is important for marketing. Data has been compiled for the period 1998–2007 for the variety Catherine, grown in the locality of Velké Bílovice in the Czech Republic. A relationship between the sum of active temperatures above 7°C from the beginning of the year up to the start of blossoming has been identified, and a model determining the harvest date on the basis of the sum of active temperatures in the periods of 30 days and 60 days after blossoming has been tested.

The study compares two methods for modeling the potential distribution of pests when applied to the European corn borer (Ostrinia nubilalisHubner). The development of the European corn borer (ECB) is known to be closely correlated with daily air temperature as well as other climate variables. The climatic parameters are, therefore, used to predict the potential geographical distribution using tested tools such as CLIMEX or ECAMON. These models consider the climatic suitability of a given site/region for the pest’s development and, thus, the possible establishment of a population at a given location. In this study, meteorological data from 1961 to 2000 and from 45 meteorological stations were used to characterise the current climate conditions in the Czech Republic. Validation was based on available field data of the occurrence of ECB in the same period. The climate parameters were later modified according to the estimates based on the combination of three SRES emission scenarios and three global circulation models. Under all climate change scenarios, we noted a marked shift of the pest’s potential niches to higher altitudes, which might lead to an increase in the infestation pressure during the first half of this century. The present area of the univoltine population will increase due to temperature increases even above 800 m a.s.l. In addition there is a risk of the establishment of a bivoltine population in the main agricultural areas and 38% of arable land in the Czech Republic before 2050.

Rainy Period

During the first part of July, 2006, a severe outbreak of disease on common snowberry shrubs, Symhoricarpos albus var. laevigata, was observed in some city ornamental parks and small gardens in Prague and its environs. Based on disease symptoms and pathogen characteristics both on leaves, shoots, fruits and in culture, it can be concluded that the outbreak of anthracnose on common snowberry was caused by Sphaceloma symphoricarpi Barus & Horsfall 1928. This is probably the first record of S. symphoricarpi in the Czech Republic. Of the surveyed Symphoricarpos species and varieties, i.e. S. albus var. albus, S. albus var. laevigata, S. orbiculatus, S. doorenbosii, and S. chenaultii, only S. albus var. laevigata was attacked by the pathogen. Common snowberry shrubs having semipendent branches appeared to be more susceptible than shrubs with upright ones. Disease symptoms and pathogen characteristics are described and illustrated. The analysis of meteorological data indicated that the outbreak of anthracnose of common snowberry might have been related with rainy and mild weather during May, and especially with a rainy period of 7 days at the end of May and beginning of June.

Experimental Plots

A higher than normal incidence of fruit doubles occurred in the Czech Republic in the 2004 season. Fruit doubles or twinning was most frequently observed among plum fruits sold in town markets, in mirabelle in small gardens in Prague and environs, and in apple, variety James Grieve, on the experimental plots of the Research Institute of Crop Production, Prague-Ruzyně. In other cases, only the terminal fruits were fully developed, usually in one apple spur, while basal fruits were retarded. Based on meteorological data and literature reports, it can be concluded that the higher incidence of fruit doubles in the CR in 2004 is correlated with heat and drought stress in 2003. The period between August 3 and August 15, 2003, was the time during which differentiating and developing flower buds might have been stressed and injured. In this period, there were high temperatures (30 to 38.9°C) each day and trees suffered water stress.
