Soil is one of the most important factors affecting the plant development on the basis. The method mostly applied for the purpose of accelerating the plant development and ensuring the increase in products is to increase the nutrients in the soil, namely fertilization. Fertilization ensures lots of food elements in the soil to get mixed in the soil and change the soil composition. Another factor affecting the plant growth speed and productivity is shadowing. Shadow conditions change the light receiving amounts of the plant and directly affect the plant photosynthesis speed. In addition; shadowing not only affects the dissolution and in-soil mixture speed of the fertilizers applied to the soil, but it also directly affects the humidity content of the soil. In this study, it has been aimed to determine the food element changes in the soil on the lavender individuals grown under different shadow conditions and fertilized with different fertilizers. The lavender used in the study has been selected due to the fact that it adapts to dry areas, it is abstinent in terms of soil and it is an important and income-generating medical aromatic plant. As a result of the study, it has been determined that shadowing statistically affects salt, carbon, phosphor, nitrogen and potassium and fertilization statistically affects phosphor, nitrogen, potassium, carbon and salt at least at 95% confidence level.

Appreciable Variation

The influence of stage of fruit development and plant growth regulators on somatic embryogenesis and the relation of cultivar response on somatic embryogenesis and subsequent plant development have been investigated in eight cultivars of pecan [Carya illinoensis (Wangenh.) C. Koch]. Explants from the micropylar region of the ovule were more embryogenic when removed from fruits in the liquid endosperm stage than were intact ovules from less-mature fruits or from cotyledonary segments of more-mature fruits. Explants conditioned on medium containing auxin alone or auxin + cytokinin produced more somatic embryos than medium containing cytokinin alone. Under the conditions of this study, frequency of embryogenesis, as well as the germination of somatic embryos leading to plant development, indicated appreciable variation among cultivars. Plant development was greatest by far from somatic embryos of `Schley' than other cultivars studied.

Significant Factors

Domestic waste from households is the biggest contributor to municipal waste management. Palangka Raya City is one of the cities that faces waste problems due to lack of awareness of the citizens. The culture of dumping garbage into river bodies is common for residents who live along the river banks. This study aims to determine waste generation and the factors affecting waste generation of household in the Palangka Raya City. The measurement of waste generation was carried out in accordance with the guidelines of SNI 19-3964-1994, while the variables that are suspected to influence the waste generation were collected by the questionnaire. To find out the factors affecting waste generation, data were analyzed by multiple linear regression. Based on the results of research conducted on 48 respondents obtained household waste generation in Palangka Raya City is 0.33 kg/person/day, while significant factors affecting waste generation are concern for the environment and income levels at a 95% confidence level and the number of family members at the 99% confidence level. While the recycling knowledge, education level, house size and installed electrical power did not significantly affect waste generation. With this information, it can be calculated the needs of TPS, the needs of the transport fleet, the needs of cleaning staff and plans for controlling household waste generation in the Palangka Raya City.

Burkholderia kururiensis is a diazotrophic bacterium originally isolated from a polluted aquifer environment and presents a high level of similarity with the rice endophyte "B. brasilensis" species. This work assessed the ability of B. kururiensis to endophytically colonize rice plantlets by monitoring different tissues of root-inoculated plants for the presence of bacterial growth in different media, electron microscopy and by 16S rDNA analysis. Observations of roots, stems and leaves of inoculated rice plantlets by electron microscopy revealed B. kururiensis colonization predominantly on root hair zones, demonstrating endophytic colonization primarily through the endodermis, followed by spreading into xylem vessels, a possible pathway leading to aerial parts. Although indifferent for the bacterial growth itself, addition of a nitrogen source was a limiting factor for endophytic colonization. As endophytic colonization was directly associated to an enhanced plant development, production of phytohormone auxin/indole-3-acetic acid by B. kururiensis was assayed with transgenic rice plantlets containing an auxin-responsive reporter (DR5-GUS). Our findings suggest the ability of auxin production by plant-associated B. kururiensis which may have a stimulatory effect on plant development, as evidenced by activation of DR5-GUS. We hereby demonstrate, for the first time, the ability of B. kururiensis to endophytically colonize rice, promoting both plant growth and rice grain yield.

The article presents the results of a field experiment to study the effects of different rates of the microbial preparation Diazobacterin under different methods of using the plant growth regulator Radostim (seed treatment before sowing and spraying crops) on the content of chlorophyll a and b in buckwheat leaves of Yelena variety, their sum and carotenoids. Determination of chlorophyll a and b, their sum and carotenoids was performed in selected samples of buckwheat leaves in the field conditions, in the phases of stem branching and the beginning of flowering according to the method described by V.F. Gavrylenko and T.V. Zhyhalova using a spectrophotometer. The pigment concentration was calculated from Holm-Wettstein's equations for 100 % acetone. It was found that the content of photosynthetic pigments in buckwheat leaves is conditioned by the weather, rates and methods of application of the studied microbial preparations and phases of plant development. In particular, the analysis of chlorophyll and carotenoid content in the early flowering phase of buckwheat plants showed a significant increase compared to the phase of stem branching, which may be due to increased physiological and biochemical processes in plants, against the background of improving mineral nutrition, growth and plant development. Thus, with the multiple use of the microbial preparation Diazobacterin in the rates of 150, 175 and 200 ml and the stimulator of plant growth Radostim in the rate of 250 ml / t for seed treatment before sowing, the content of chlorophylls a and b, their sum and carotenoids with increasing application of Diazobacterin increased and the excess relative to control ranged within: 29–31 % for chlorophyll a; 10–11 % for chlorophyll b; 24–26 % for their sum and 23–24 % for carotenoids. At the same time, with a complex application for pre-sowing seed treatment of a mixture of the microbial preparation Diazobacterin in the rate of 200 ml per hectare of seeds with the stimulator of plant growth Radostym in the rate of 250 ml / t followed by spraying on this background crops the stimulator of plant growth Radostim in the rate of 50 ml / ha buckwheat leaves form the highest content of chlorophyll a in comparison with the control (40 %); chlorophyll b (15 %); the sum of chlorophyll a + b (33 %) and carotenoids (29 %). These data indicate the creation of more favorable conditions for physiological and biochemical processes in plants, including photosynthesis, with the direct positive effect of which, functionally active pigment complex of the leaf apparatus of buckwheat is formed.

Growth Experiments

Commercially produced membrane rafts containing Celgard D-304 microporous, polypropylene film are used to support the growth of micropropagated plants in liquid media. This method is used because growth experiments using membranes resulted in plant growth rates equal to or greater than those grown on agar. Inconsistent results of plant growth on these rafts led to an interest in measuring the water vapor transmission rates (WVTR) of the membranes. A modified WVTR test (ASTM E96-80) was used on 15 raft samples. Results showed that the supplier's value of 49.2 g/m2 ·hr falls within the range of measured values of 39.2 to 54.8 g/m2·hr. Inconsistencies in growth of micropropagated plants may not be due to variability in the WVTR of the Celgard film. It is possible that the WVTR of the film is not the most important factor in facilitating liquid nutrient transport across the membrane. Other properties of the film need to be measured to determine factors affecting growth rates observed.
