“…This delay, in turn, contributes to an increase in the yield of the plant (Tao et al, 2006). The results from research show that correct growth and development of cucumber in all of its stages, requires sufficiently high T a (Lederle and Liebig, 1985a;Babik, 2004;Kalbarczyk, 2009b). Some authors suggest that soil warming partly counteracts the unfavourable influence of low T a at night on the growth of thermophilous plants (Ingratta, 1980;Liebig, 1985a).…”

Growing influence of anthropopressure and irregular changes in weather conditions necessitated conducting agroclimatic research into the assessment of plant cultivation risk caused by unfavourable meteorological conditions, including thermal conditions of air. The goal of the work was to assess the risk of pickling cucumber field cultivation in Poland caused by an unfavorable course of air temperature (T a ) in the period from sowing to the end of harvesting at the turn of the 20 th and 21 st centuries. To accomplish the goal, the study used data describing growth, development and crop productivity of cucumber in the years 1966-2005. Data was used concerning the described thermal conditions with the average T a in the whole growing season of the analysed plant. The data came from 28 experimental stations and 53 meteorological in Poland. The effect of T a in the growing season (sowing-end of harvesting) on the total and marketable yield of cucumber was evaluated. The study used curvilinear regression analysis with two variables. The highest risk of cucumber's cultivation caused by unfavorable thermal conditions of air was recorded in south-western, south-eastern, and also northern and north-eastern Poland. In these high risk areas reduction in the total yield oscillated between 15% and even over 21% below the multi-annual average. Reduction in the total yield occurred with frequency from 40% to above 80%. In south-western and south-eastern Poland, a reduction in the marketable yield amounted to maximally above 15%. A marketable yield reduction occurred with a frequency of from 50% to above 70%.Additional key words: air temperature; climate changes; growing season; reduction in yield. ResumenLas condiciones térmicas desfavorables del aire reducen la productividad de los cultivos de pepino encurtido (Cucumis sativus L.) en Polonia en el cambio de los siglos XX y XXI La creciente influencia de la acción humana y los irregulares cambios en las condiciones climáticas han hecho necesario llevar a cabo investigaciones agroclimáticas para evaluar el riesgo en el cultivo de plantas. El objetivo de este trabajo fue evaluar el riesgo en Polonia en el cultivo en campo de pepino, en el cambio de los siglos XX y XXI, causado por una evolución desfavorable de la temperatura del aire (T a ) en el período desde la siembra hasta el final de la cosecha. Se utilizaron los datos, obtenidos de 28 estaciones experimentales y 53 meteorológicas en Polonia, que describen el crecimiento, desarrollo y productividad de los cultivos de pepino en los años 1966-2005, relacionándolos con la T a media en todo el período vegetativo de la planta. Se evaluó el efecto de la T a en la temporada de cultivo (siembra-final de cosecha) sobre la producción total y comercial del pepino, utilizando un análisis de regresión curvilínea con dos variables. El mayor riesgo del cultivo de pepino debido a las desfavorables condiciones térmicas del aire se registró en el sur-oeste, sudeste y también norte y noreste de Polonia. En estas zonas de alto riesgo l...

“…Grafting has many benefits to plants grown in plastic houses, such as increasing tolerance to low temperature (Liebig, 1984), tolerance to soil salinity (Matsubara, 1989), and resistance to soil borne diseases (Oda, 1995). Eguchi and Koutaki (1986) reported that cucumber plants grafted onto C.ficifolia could be used for widespread cucumber production, as the grafted plants were more vigorous than the non grafted ones.…”

In this study, the effect of different rootstocks on cucumber survivals %, plant growth, fruit, yield and quality were studied by comparing grafted plants with nongrafted ones under plastic house during the winter seasons of 2010/2011 and 2011/2012, The cucumber (Cucumis sativas L,) c.v Balqis F1, was grafted onto 6001 (C.shantosa), Strong (C.mixita), Gumbo (C.maxima), Bottle gourd (Legenaria sosiraria), Vegetable sponge (Luffa cylindrica) and pumpkin (C.moschata). C.V Balqis F1 Non-grafted plants were used as control. Grafting significantly affected survival % , stem length ,stem diameter, internodes length , leaf area , plant fresh and dry weight. Control plants had low survival %, short stem length, internodes length and low leaf area, plant fresh and dry weights in both seasons. The highest number of flower/node, per plant and fruit setting % values were obtained from plants grafted onto 6001 followed by those grafted onto strong. The highest early yield and total yield per plant as a number and weight were obtained from plants grafted onto 6001 followed by the grafted onto strong. Grafting cucumber onto 6001 significantly increased fruit weight, length and shape index.

“…verificaram que o porta-enxerto "Tetsukabuto" aumentou a a produtividade do cultivar Ancor em 5,4% e diminuiu a de Nikkey em 15,6%, provavelmente, segundo os autores, devido ao aumento no vigor vegetativo do enxerto causado pela enxertia sobre este híbrido de abóbora. Liebig (1986), estudando os efeitos da temperatura no pepino, concluiu que a enxertia pode ser recomendada como forma de conferir tolerância às plantas a períodos curtos de frio. As plantas enxertadas sobreviveram a uma temperatura de 10ºC, enquanto que a temperatura mínima suportada pelas plantas não enxertadas foi de 14ºC.…”
