Today, the entire world is facing with the response of the nature to anthropic factors, also called climate change. Thereby, the impact of climate change is manifested globally, in all areas and sectors, including agriculture. This, as the main food supplier, is strictly dependent on the quality of the soil resources, which is in a continuous depreciation. The aim of this paper is to present some data related to Amaranthus sp., Limonium sp., Portulaca sp., and Festuca sp. grown in greenhouse conditions, on different types of soil, with pH and conductivity known in order to establish plant adaptability for soil remediation, using image analysis.

In Romania the climate is temperate continental, but climate change from recent times fragmenting this climate into one with nuances of excess. This is due to large temperature variations between the hot and cold seasons, but also of large temperature differences between day and night. In addition to these aspects, the uneven distribution of precipitation as well as extremely large variations in their total quantity registered from one year to another negatively influences the growth and fruiting of grapevine plants. This paper presents methods and systems for detecting water stress in viticulture. Among the most commonly used instruments are tensiometers and soil psychrometers to measure directly the capillary tension or energy with which water is withheld by the soil. [ABSTRACT FROM AUTHOR]

Recent climate changes, characterized by the rising of global temperatures and extending periods with extreme climatic phenomena, directly influence the quantity and quality of vegetable crops. Counteracting or mitigating the effects of climate change can be done through an appropriate strategy that involves the biological element (genotype) and the technological elements that can be applied to the cropps. In this paper, three tomato lines (L- 75, L-76, L-1.03) which are being elaborated at Vegetable Research and Development Station Buzau (V.R.D.S.) Buzau, Romania, were analyzed. The purpose was to investigate the response of plants (seedlings), which posses high nutritional value and ecological plasticity, from the selected tomato lines and cultivated under laboratory controlled conditions, on the performance of some physiological parameters, following the application of the additional light emitted by blue-light -emitting-diodes (LEDs).

This paper presents an analysis of the seedlings found in the Banu Mărăcine viticultural center, the degree of spreading, as well as some aspects related to their biology and ecology. It was used the method of comparative observation on the evolution of weeds and the changes which appear due to climatic factors. [ABSTRACT FROM AUTHOR]

This paper presents the The researches took place at the Bujoru Vine-Growing Research and Development Stage in 1992-2016 and targeted the spread of the main pathogens and pests in the vineyard plantations, an ecological phenomenon that is influenced by ecological zonal factors and ecological plasticity, each species occurs in nature on a given territory occupying a determined area. After analyzing the dynamics of the vineyard health status of the Bujoru viticulture ecosystem in the last 25 years, it is observed that the occurrence and evolution of the main pathogens were influenced by the climatic conditions area. In the vineyard plantations of the Bujoru vineyard, harmful fauna is relatively varied and numerous, but only a few pathogens (manna, mildew, gray rot) produce year-on-year significant economic damage. Pathogens were monitored by notaries observations and scores to determine the frequency (F), intensity (I) and attack rate (G.A %). [ABSTRACT FROM AUTHOR]

The vineyards in the south of Moldova are increasingly affected by climate change occurring over the last period. Reducing crop quality and quantity a hub of grape vineyards and affecting the occurrence of early winter frosts and excessive negative temperatures, the late spring frosts and drought of the vegetation period, result in significant losses for vineyard property. Witnessing lately to torrential rainfall, prolonged drought, excessive years of normal or dry years followed by rain. All these aspects influence of soil water reserves have mostly hydric deficit since June. The paper presents analysis of rainfall and soil humidity regime. For analysis of rainfall were recorded at weather station data used to SCDVV Bujoru. They collected soil samples monthly, on the horizon 0-100 cm, from 20 to 20 cm. With hydro index was calculated soil moisture in the soil available. Analyzed during the early vegetation period the soil water reserve is located in the humidity range of 55-70% of assets and soil water deficit is greatest in August. [ABSTRACT FROM AUTHOR]

Potato (Solanum tuberosum L.), the third (after wheat, corn and rice), most important food in the world is currently suffering from climate change. The potato crop is strongly influenced by the amount of precipitation and their distribution. The present study was conducted to determine the cultural behavior, respectively the response to hydric stress of some clones from the National Institute of Research and Development for Potato and Sugar Beet Brasov. Two factors were tested: factor I - potato breeding lines 27; factor II – culture medium (clasic medium Murashige –Skoog and medium Murashige –Skoog with osmotic agent). 1982/3 clone was identified with high values and significant differences in case of medium with PEG in 2% concentration, for the number of leaves/plantlets and for root lenght. Also, 1939/2 clone was identified with high values for the number of leaves/plantlets and 1982/1 clone for the root length. 1958/3 clone presented high values for two of the analyzed parameters: plantlet length and fresh plantlets weight, when was applied PEG 2% in the nutrition medium.

This study presents the first results on the non-destructive, DA meter-based optimum harvest maturity model for some disease-resistant apple cultivars, cultivated in the Bucharest area. Seven scab-resistant cultivars (Iris, Generos, Remar, Redix, Rebra, Ciprian, and Florina) were analyzed. The results bring important details about the pre-harvest and harvest maturation of the studied cultivars using the lAD index. Given the climate changes, this instrument can be accurately used to assess the maturity level of fruits, taking into account the particularities of each cultivar. In order to establish an optimal model for each cultivar, further researches are needed to correlate the optimal harvesting period index (IAD) with the required post-harvest period. DA-meter could be an important instrument to estimate the optimal parameters for self-life, also. [ABSTRACT FROM AUTHOR]

The aim ofthe current research was to assess some climate indicators such as temperature and precipitation relevant to 1972-2011 period at eight locations belonging Konya city of Turkey. In such study, trends in such parameters were analyzed by usage of Non-Parametric Mann-Kendall Test. In Konya general, increasing trend was found at absolute maximum temperature, and number of summer and tropical days. The decreasing trend related to absolute minimum temperature was detected. Although maximum rainfall was obtained from both winter, and spring seasons followed by autumn, the lowest one was observed at summer season. There was found important reducing trend at only Kulu and Karapinar places relevant to spring precipitation. In that regard, water resources should be managed with great care for reducing negative effects of climate changes on agro-production areas particularly water shortage regions such as Konya Closed Basin, Turkey.

In the context of climate change, increasing temperatures and reducing precipitation are stress factors for watermelon plants. In order to determine the resistance of native varieties to stress factors, the Dulce Dabulni, Oltenia and De Dabuleni varieties were studied using two watering ceilings: watering according to the technology specific to sandy soils and watering reduced to 1A. The main physiological processes number of fruits/plants, the average weight of a fruit, its production and its quality were determined. Under reduced watering conditions, at watermelons reduced their photosynthetic yield, and sweating losses were higher. The number of fruit/plant was maintained at both watering ceilings, instead the average weight of a fruit and the yields produced were higher in the optimally watered variants. At the minimum ceiling, a higher total dry matter and vitamin C was obtained, and at the optimum ceiling, higher levels of soluble dry matter and carbohydrates were obtained. The highest resistance to thermal the stress was due to the Oltenia variety, which achieved an average fruit weight of 6.1 kg/fruit and a production of 38.2 t/ha under conditions of low watering.
