Recent studies revealed that from various ecological factors influencing nectar yield and quality of a plant, soil properties can be as important as microclimatic features. To date, few studies have investigated the relationship of soil characters to nectar traits of bee pollinated plants growing in natural associations. Our study intended to reveal which soil properties had the most powerful impact on nectar variables of wild garlic (Allium ursinum L.). Specimens were collected from fourteen habitats in two different years, and were potted in their original soil under the same climatic conditions. Nectar volumes and sugar concentrations were measured and soil samples were analysed for fourteen parameters. Statistical analyses revealed that the number of nectar producing Allium flowers, as well as the nectar volume and sugar content of nectar in individual flowers were influenced by both year and habitat. The humus, iron and sulphate content of soil showed negative correlation with the number of flowers producing nectar; total nectar volumes were negatively correlated with humus and iron content, but positively affected by magnesium content of the soil. Our results suggest that in addition to the effect of microclimatic factors, certain soil properties can have significant impact on nectar traits.

Fertilization Level

Soil tillage and fertilization level are important in the system of agro-technical measures that increase soil fertility and sugar beets productivity. Today the cultivation of this crop requires a great deal of expense, therefore, there is a need for a wider study of the use of cheap soil cultivation, soil protection, energy-saving soil tillage technologies and appropriate ferti-lization levels. Under western Forest-Steppe of Ukraine conditions, investigations were conducted on dark grey podzolic light loamy soils where the influence of tillage models and fertilization levels on the formation of sugar beets root crops was studied. Shallow no-plow tillage of the soil on 14-16 cm is expedient to use as a main tillage under sugar beets. Under favorable weather and climatic conditions, it can provide yielding capacity at the level of deep fall plowing. The use of shallow no-plow tillage helped to increase the yielding capacity of sugar beet roots relative to plowing by 28-30 cm for 1.3 t / ha and the biological sugar output – for 0.2 t / ha. Then the sugar content was by 0.1% higher in the application of deep fall plowing on 28-30 cm. The optimization of the system of sugar beets fertilization allows ensuring the growth of the yielding capacity of root crops. It is established that the application of fertilizer norm N300P225K350 provides the yielding capacity at the level of 90 t / ha. The sugar content of root crops at the given fertilizer rate was the lowest in the experiment - 16.5 – 16.6%. Thanks to the high yielding capacity of root crops in terms of N300P225K350, the sugar harvesting was the highest and depending on the method of basic soil tillage was 14.95 – 14.79 t / ha. That is in 3.2 times more as to the control, in 1.3 times more than the norm of N180P135K210 and in 1.1 more than the fertilization level N240P180K280.

Abstract:Nectarivorous flower mites can reduce the volume of nectar available to pollinators. The effects of the flower mite Proctolaelaps sp. on nectar availability in flowers of a melittophilous bromeliad Neoregelia johannis (Bromeliaceae) was evaluated in a coastal rain forest in south-eastern Brazil. In a randomized block experiment utilizing 18 flower pairs, one per bromeliad ramet, pollinators (Bombus morio) and mites were excluded, and then nectar volume, sugar concentration and sugar mass were quantified over the anthesis period. Mites significantly reduced nectar volume early in the morning (6h00–8h00), but not later (10h00–12h00). Mites decreased total volume of nectar available up to 22%. Sugar concentration in nectar was higher earlier in the morning, and decreased between 10h00–12h00. The pronounced consumption of nectar by mites during the period of higher sugar concentration reduced the total amount of sugar available to pollinators by 31%. This is the first study showing that flower mites decrease nectar rewards in a melittophilous plant. Because nectar volume by itself incompletely describes nectar production rates and the effects of nectar removal by flower mites on the availability of sugar, our study highlights the inclusion of sugar content in future studies assessing the effects of thieves on nectar production rates.

Abstract Nowadays the study of the interrelation of the genotype of strawberry plants in garden and climatic conditions is extremely relevant. Due to the various systems of genetic control and the modifying effects of growing conditions on the manifestation of quantitative traits, there is the need to assess the genotypic variability of economically valuable features, focused on the identification of genotypes characterized by stability and adaptive qualities in growing conditions. The study examined 15 varieties of garden strawberries of domestic and foreign selection. The field experiments and surveys were carried out according to the Program generally accepted in the Russian Federation and methodology for the variety study of fruit, berry and nut crops. We studied such features as the number of peduncles (pcs/bush), number of berries (pcs/bush), average weight of berries (g), total and marketable yield (g/bush), sugar content in berries, soluble solids and ascorbic acid. The purpose of this work was to assess the genotype-year interrelation in terms of the variability of productivity features and berry quality and to identify strawberry varieties with a stable genotype. As a result of two-way analysis of variance for the variety-year interrelation, the obtained values were 1.10-8.50 at standard Fst. - 1.24. Statistically important differences had indicators of productivity of a bush between the first and second clusters (t = 5.89 at p <0.01), the first and third (t = 15.83 at p <0.01), the second and third clusters (t = 8.13 at p <0.01), as well as the average berry weight between the first and third, second and third clusters (t = 15.50 and 6.99 at p <0.01, respectively). Significant differences in the value of the Euclidean distance were revealed for varieties Mishutka (54.5), Daryonka (54.5), Pervoklassnitsa (58) realizing their productivity potential in different years of cultivation.

Abstract. Yulistyarini T, Fiqa AP, Budiharta S, Rindyastuti R. 2020. Distribution of Gyrinops versteegii in varying vegetation structures, soil properties, and microclimates in western part of Flores Island, Indonesia. Biodiversitas 21: 1800-1808. Gyrinops versteegii is one of the agarwood-producing tropical plants that is distributed in the Lesser Sunda Islands to Sulawesi, Moluccas (Maluku), and Papua. The natural population of Gyrinops versteegii (Gilg.) Domke is widely exploited, making it being listed in CITES Appendix II. Despite largely exploited, information regarding the distribution of G. versteegii to reveal the habitat characteristics of its natural population is limited. The aims of the research were (i) to investigate the habitat characteristics of the distribution of G. versteegii in term of vegetation community, as well as soil and microclimate variables in its natural habitat in western part of Flores Island, and (ii) to study the relationship between its occurrence and ecological factors. The research was conducted in one community forest and three natural forests in the districts of Manggarai and West Manggarai, Flores Island, East Nusa Tenggara Province. Data on vegetation, soil properties and microclimates were collected by establishing 73 observation plots across the four studied areas. Data were analyzed to reveal vegetation composition and structure where G. versteegii occurred, the dispersion pattern, and relationship between its occurrence and ecological factors. Our study revealed that G. versteegii populations at four studied areas in Flores Island were distributed in a broad range of habitat characteristics with varying vegetation compositions and structures, canopy covers as well as soil and microclimates variables. The local/metapopulations of G. versteegii in these areas can be dispersed in clumped or uniform pattern. Nonetheless, some ecological variables might be important for the abundance of this species including soil texture, soil pH, C organic and Soil Organic Matters (SOM). The results of this study suggest a promising opportunity for the conservation efforts of G. versteegii through the possibility of planting this species in various land management including planted in monoculture system, polyculture system (e.g. home garden and agroforestry) as well as reintroduced into species-rich natural forest.

The impacts of agro-pastoral activities on soil properties, plus nutritive value and residual standing biomass of herbaceous plants in areas of different land uses in western Serengeti, were evaluated. Vegetation and soil were sampled along 4,000 m transects laid across fallow land, areas grazed only by livestock, mixed grazing (livestock and wildlife) and wildlife grazing only. A total number of 123 plant species were encountered during sampling. Analyses of soil and vegetation samples were conducted at Sokoine University of Agriculture laboratories. The estimated average density of grazing animals encountered was 160 TLU/km2 on transects within livestock-dominated grazing lands, 129 TLU/km2 for mixed grazing and 83 TLU/km2 for wildlife grazing only. Results indicated that ADF, IVDMD, IVOMD, ME and TDN in residual herbaceous forage at flowering were significantly (P<0.05) affected by land use type but CP, NDF and ADL were not affected. Soil pH, OC, CEC, C:N ratio and Ca differed significantly (P<0.05) between land use types. An overall evaluation indicated that regardless of climatic conditions, residual biomass of herbaceous plants in western Serengeti is determined by intensity of grazing, soil C:N ratio and concentrations of Ca and P in the soil. We conclude that agro-pastoral practices conducted in western Serengeti affected residual standing biomass of herbaceous plants and soil properties. We recommend that grazing pressure in communal grazing lands be reduced by either reducing number of grazing animals or duration of grazing in a particular grazing area, and specific studies be conducted to establish stocking rates appropriate for specific communal grazing lands in villages.

Replacement of topsoil to an appropriate depth is one of the key methods for ecological restoration. The objective of this study was to investigate the effects of topsoil replacement depth on vegetation and soil properties, and to identify the optimum soil depth for reclamation of coal mine spoils in a cold alpine mining area. We sowed 3 herbaceous species after coal mine spoil heaps were treated with topsoil to 3 depths (0, 20‒25, 40‒45 cm). The variations in vegetation community structure, plant growth, soil properties were measured at different replaced topsoil depths. The correlations between plant and soil properties were analyzed statistically. The results showed species richness, diversity and evenness were not significantly different among different depths of topsoil (P > 0.05). Vegetation coverage, density, height and aboveground biomass increased significantly (P < 0.05) with increasing topsoil depth. Soil properties did not change significantly with increasing topsoil depth (P > 0.05), but soil organic matter was significantly higher at 40‒45 cm topsoil depth than at other two depths (P < 0.05). All soil properties, with the exception of total potassium, were positively correlated with the plant growth parameters. The 40‒45 cm topsoil depth of replacement should be considered as effective method in reclaiming coal mine spoils. The use of both topsoil replacement to a depth of 40‒45 cm and sowing of suitable herbaceous seeds is found to be an effective restoration strategy. Additionally, fertilization might be used as a substitute for artificial topsoil replacement to improve soil quality and speed up revegetation process by the positive plant-soil interactions.
