The paper presents some aspects regarding the influence of climatic conditions (temperature, precipitation, humidity, etc.), the annual increases in some species of woody plants. The objective pursued was the determination of the length of the annual increases in the climatic conditions of the Iaşi 2013-2015. 2015 can be characterized as a year with relevant climatic peculiarities of what has negatively impacted the annual increases in comparison with annual increases in 2013 and 2014.

The apple blossom weevil (Anthonomus pomorum L.) is dispersed in almost every European country in the pome fruit growing regions; in Romania it can be observed between the Quercus forest steppe region and the steppe region, the economic impact being very important due to the damage produced by the pest which can achieve very high rates of losses. Forecasting the main biological development stages of the pest is a key element in the control of this pest.The main research objectives of the experiment were: the study of the biology of colonization dynamics of the pest according to the biological development stages; the comparing of the efficiency of two monitoring techniques: classical limb jarring method and newly designed bubble wrap method; the study of the main meteorological factors which had an impact of the apple blossom weevil biology. Capture results by the two monitoring techniques show close values, the seasonal culmination of the apple blossom weevil colonization occurred at the end of March (27.03.2015) with more than 50 adults/tree. Observations were effectuated according to the phenological stages of apple bud development (BBCH method); feeding of both female and male adults occurred between silvery green tip (BBCH 52) and pink bud stage (BBCH 57), thus crawling, feeding, mating, oviposition occurred on the days with temperatures above 6 ˚C. For every holometabolic development stage it was calculated the sum of temperatures at the beginning and at the end of the biological phase. For the newly designed bubble wrap method there where used two kind of bubble wrap types, results showed that the bubble wrap with larger spaces within the bubble wrap is more suitable for the weevil capture than smaller ones. With the use of the transparent bubble wrap method it was possible not only the reutilization of the wrap by tightening back on the trunk of trees but also the easy numbering of weevils without the risk of damaging the buds and the branches. The gathered data indicated that the main environmental factors expressed by the mean, minimum, maximum temperatures, relative humidity and rainfall influenced directly the completing of the biological developmental stages of the apple blossom weevil (Anthonomus pomorum L.).

The work presents the results of research and analysis conducted in 2002-2009, the Republic of Moldova regarding the influence of climatic conditions on passing the phenological phases of development and berries quality of introduced raspberry varieties. Is established that, the climatic conditions influence directly the development of raspberry varieties and berry quality, in particularity on bud break, flowering and ripening time. As a result of scientific researches it is established that: installed from the beginning of bud break to start flowering blooming in floral clock runs at an average of 28-51 days. From the start of flowering until the raspberry berry maturity is an average 27-47 days. Maturation begins in the second-third decade of June. Varieties which the fruit mass more stable regardless of the amount accumulated rainfall and temperature established with both these varieties are more resistant to drought. As you increase the number of erratic rainfall of 376.4 mm to 660.3 mm, weight gain without irrigation berries grade ranging from +0.1 till +2.1g .

This paper shows the results of studying the varieties of blackberry ‘Darrow’, ‘Thornfree’, ‘Smoothstem’ to obtain organic production in the climatic conditions of the Republic of Moldova. The research was based on monitoring the phenological, organoleptic, and biometric indicators in 2011, 2013 and 2014. The use of varieties with increased resistance to environmental conditions, pests and diseases is one of the essential ingredients, originated from the organic farming. During the years 2013-2014 in all varieties studied was not observed frostbites on blackberry plants, no symptoms of disease and pest attack. Biochemical composition of fruits was determined to remark the nutritional qualities and taste of organic blackberry fruit. In assessing the coefficient sugar / acidity, best manifested variety was ‘Thornfree’ by the average amount of 2.87, followed by ’Smoothstem’ variety - 2.76. After the dry matter content, stands out the Smoothstem variety, by the average amount of 12.02% for the period studied, but by the content of vitamin C is predominant the variety ‘Darrow’ with thorns by the average amount of 26.13 mg%. Regarding the level of productivity, the highest yields in 2014 were obtained from varieties without thorns, especially the variety ‘Thornfree’ with a value of 7.64 kg in a bush.
