Abstract:

The aim of this research is to optimize growth and development of maize for biomass by selecting maize hybrids to fulfill their productivity potential. The following maize hybrids were the subject of research: Forteza, DM Native, DM Skarb. The greatest height of plants was formed in the interphase period of milk-wax maturity of grain in hybrid Forteza – 286.4 cm. In hybrid DM Native the height of plants was – 271.2 cm, hybrid DM Skarb – 263.6 cm. Weight of one plant of hybrids studied during the maize growing season ranged from 442 g to 760 g. Thus, the largest mass of maize plants was recorded in the milk-wax maturity stage. It was the largest at the hybrid Forteza and amounted to 760 g, that is more than at the hybrid DM Native for 3.4% (26 g) and at the hybrid DM Skarb for 6.6% (50 g). The average crop yield of the hybrid Forteza for the period of research was 55.1 t ha-1. Hybrids DM Native and DM Skarb provided this indicator at the level of 50.6 and 45.7 t ha-1 respectively. Hybrid Forteza provided a maximum crop yield 55.1 t ha-1 with plant height 286.4 cm, assimilation surface of one plant and a crop 0.59 m2; 42.8 thousand m2 ha-1 and plant weight 760 g.

Abstract:

During the last decade the introduction of more environmentally friendly technologies were raised more rapidly by the decline in the global fossil energy resources and the increased negative environmental impact of conventional vehicles. One of such technology is the hybrid, which is currently making the transition from conventional vehicle with internal combustion engine to an electric vehicle. At this time there exist a lot of offers of such vehicles from different manufacturers, but there do not exist many researches connected with real hybrid performance in different road cycles and conditions allowing evaluate its real economical performance.
This research was realized with the aim to evaluate performance and fuel consumption of hybrid electric vehicle and its conventional internal combustion engine analogue in laboratory conditions. Tests were realized with two new Toyota Yaris vehicles in Alternative Fuels and Research Laboratory on chassis dynamometer MD-1750 using AVL KMA Mobile system. The results showed better adaptation of Toyota Yaris Hybrid to urban operation, demonstrating 21.3% lower fuel consumption than Toyota Yaris conventional gasoline vehicle, accordingly 7.29 and 8.84 L (100 km)-1.

Abstract:

A cooperative blackcurrant breeding project between Sweden, Russia, Latvia and Lithuania studied yield, resistance to fungal diseases and pest, biochemical composition of berries of 20 new blackcurrant cultivars and hybrids at the Lithuanian Institute of Horticulture in 2004-2008. The blackcurrants were cultivated without plant protection against either diseases or pests. Yield, damage by fungal diseases and pest and biochemical composition was investigated. The hybrids BRi 9504-5, BRi 9568-1A, BRi 9508-3A and BRi 9508-3B were selected as possible cultivars.

Abstract:

Thirty apple (Malus domestica Mill.) cultivars and hybrids were evaluated for resistance to scab (Venturia inaequalis (Cke.) Wint.), apple blotch (Phyllosticta mali Pr.at Del.) and canker (Nectria galligena Bres.). Resistance to scab and apple blotch were studied in 2003–2005 and to canker in 2005. Injuries caused by fungal diseases were evaluated according to a 6 point scale: 0 – no disease symptoms detected on leaves or branches, 5 – injured more than 75% of leaf area or, in the case of canker, the branch is girdled by distorted area. Meteorological conditions were favourable or moderately favourable for the development of pathogens. It was ascertained that apple hybrids No 20429 and No 20016 are characterized as complex-resistant to scab, apple blotch and canker. Cultivar ‘Kurnakovskoe’ and hybrids No 19399, No 19707, No 19646, No 19942, No 20235, No 20239, No 20978 and No 24-40-52 are characterized as complex-resistant to scab and apple blotch. Cultivars ‘Delikates’, ‘Anteĭ’, hybrids No 25-50-126 and No 25-50-132 were the most sensitive to scab; ‘Pamyať Syubarovoĭ’ and No 25-51-122, to apple blotch, and ‘Katja’, ‘Yubilyar’, ‘Pamyať Syubarovoĭ’, ‘Bolotovskoe’ and No 19942, to canker.
