Some Characteristics Of Transpiration Of Promising Soybean’s Varieties

The article presents data obtained from the study of the daily intensity of transpiration during the flowering stage of soybean varieties. According to the data on the diurnal variation of transpiration intensity, this process was accelerated in Vilana and Ustoz MM-60 varieties of soybeans, and a relative decrease in intensity was observed in Baraka and Tomaris man-60 varieties. Different variations in the intensity of transpiration in the cross section of the studied varieties may depend on the biological characteristics of the varieties as well as the air temperature and its relative humidity level.

Impact Assessment of Houseplants on Atmospheric Relative Humidity in the Residential Buildings of Udaipur, Rajasthan

Flora is the nature’s most precious gift to man. In ancient times, regard and love for flora was so great that this kindred relationship was extended even to houseplants. In this study, relative humidity level in the selected rooms, i.e., drawing rooms and dining rooms of the 10 west facing residential buildings along with the National Highway- 8 in polluted zone, of Udaipur Rajasthan was analyzed. Four varieties of foliage and succulent plants were kept in one, two or four suitable corners with four different habits, viz., Opened and Closed windows and fan in ON and OFF mode. To find out the existing relative humidity level, all the experiments were done without any houseplants on day 1 in selected rooms. The houseplants were kept on day 2 to judge the impact of houseplants on humidity level and again houseplants were removed on day 3 to know the retention of impact of houseplants. As a result, it was found that foliage plants were more effective than succulents in maintaining the level of relative humidity of the atmosphere.

Effects of Humidity and Heat on the Conductivity of Poly(3-Alkylthiophenes)

ABSTRACTThe stability of the conductivity of poly(3-alkylthiophenes) has been studied in controlled environmental conditions. High humidity levels at elevated temperatures have been found to strongly influence the dedoping process. Highly FeCl3-doped samples lose their conductivity faster than lightly doped or undoped polymers. The conductivity of undoped poly(3-octylthiophene), however, initially increased by nearly two orders of magnitude as the relative humidity level was raised from 50% to 95% at 70 °C. The largest conductivity decay induced by humidity and heat was observed in thin samples. Measurements of the field-effect mobility reveal that the humidity-induced drop of the conductivity is caused by a decreasing number of active dopants, whereas heating the sample additionally results in a deterioration of the charge carrier mobility.

Influence of different temperature and relative humidity levels on the mycelial growth, conidial germination and anthracnose incidence of Colletotrichum gloeosporioides

Mango anthracnose caused by Colletotrichum gloeosporioides is a highly destructive pathogen that causes considerable damage, inflicting severe qualitative and quantitative losses. Among the external factors which influence the growth of fungi, temperature and relative humidity plays an important role. Each pathogen has got its own cardinal temperature and relative humidity, also understanding about these factors will help to standardize the management strategies. Among the six temperature levels tested, 25°C was found to be more conducive for the mycelial growth (88.33 mm), conidial germination (69.00%) of C. gloeosporioides, and maximum disease development (97.00 %) which was followed by room temperature (28+2°C).The maximum disease incidence of 97.00 per cent in the fruits was recorded at 25oC followed by room temperature (28±2oC) (83.33 %) after 10 days of inoculation. Among the seven relative humidity levels tested, the maximum mycelial growth (87.00 mm), conidial germination (72.00%) and maximum disease incidence (97.00 %) was recorded at 100 per cent relative humidity, which was followed by 92.9% relative humidity level (83.00 mm; 61.67% mycelial growth and conidia germination, respectively). The least mycelial growth (7.33 mm) and conidial germination (0.0%) was recorded at 36.8% relative humidity level.
