2021-01Climate change is causing temperature increment in crop production areas worldwide, generating conditions of heat stress that negatively affect crop productivity. Tomato (Solanum lycopersicum), a major vegetable crop, is highly susceptible to conditions of heat stress. When tomato plants are exposed to ambient day/night temperatures that exceed 32 °C/20 °C, respectively, during the reproductive phase, fruit set and fruit weight are reduced, leading to a significant decrease in yield. Processing tomato cultivars are cultivated in open fields, where environmental conditions are not controlled; therefore, plants are exposed to multiple abiotic stresses, including heat stress. Nonetheless, information on stress response in processing tomatoes is very limited. Understanding the physiological response of modern processing tomato cultivars to heat stress may facilitate the development of thermotolerant cultivars. Here, we compared two tomato processing cultivars, H4107 and H9780, that we found to be constantly differing in yield performance. Using field and temperaturecontrolled greenhouse experiments, we show that the observed difference in yield is attributed to the occurrence of heat stress conditions. In addition, fruit set and seed production were significantly higher in the thermotolerant cultivar H4107, compared with H9780. Despite the general acceptance of pollen viability as a measure of thermotolerance, there was no difference in the percentage of viable pollen between H4107 and H9780 under either of the conditions tested. In addition to observations of similar pollen germination and bud abscission rates, our results suggest that processing tomato cultivars may present a particular case, in which pollen performance is not determining reproductive thermotolerance. Our results also demonstrate the value of combining controlled and uncontrolled experimental settings, in order to validate and identify heat stress-related responses, thus facilitating the development of thermotolerant processing tomato cultivarsSingh, Prasant Kumar
2016In the present paper, we presented the study of complaints on thirteen (13) different health symptoms faced by inhabitants living near mobile tower – Global System for Mobile Communication (GSM 900) and those inhabitants living in the area where there is no mobile tower. The study was conducted in two different localities in Aizawl in the year 2014. For the study, questionnaires were conducted in both the localities. Power densities were measured in different places in both the localities. Frequency spectrum was taken in each locality. Health complaints between the two localities were compared. It was found that power density is much higher in the area where there is mobile tower than the area where there is no mobile tower. Inhabitants living near mobile tower are having more health complaints than those inhabitants living in the area where there is no mobile tower. Responses from inhabitants who participated in the questionnaire from both the localities were statistically analysed and compared by performing Kruskal Walli’s t-test. Out of the thirteen (13) different symptoms studied it was found that the comparisons are statistically significant with p < 0.05 in six (6) symptoms. Women were statistically more affected (p < 0.05) thanRai, Dibya Prakash

2018Fishes of the genus Hemimyzon Regan, 1911, family Balitoridae, are found in the fast-flowing rivers of Southeast and East Asia, particularly in China, Taiwan, Thailand, Laos and Vietnam. The genus is very similar to the genus Balitora and can be separated mainly by having 3-7 simple pelvic rays and a more or less widened body, with pelvic-fin bases from widely separated to fused posteriorly (Kottelat, 2012). There are 16 valid species in the genus viz. H. confluens Kottelat, 2000, H. ecdyonuroides Freyhof & Herder, 2002, H. elongatus (Chen & Li, in Li & Chen, 1985), H. formosanus (Boulenger, 1894), H. khonensis Kottelat, 2000, H. macropterus Zheng, in Zheng & Huang, 1982, H. megalopseos Li & Chen, 1985, H. nanensis Doi & Kottelat, 1998, H. nujiangensis (Zhang & Zheng, in Zheng & Zhang, 1983), H. papilio Kottelat, 2000, H. pengi (Huang, in Zheng, Chen & Huang, 1982), H. pumilicorpora Zheng & Zhang, 1987, H. sheni Chen & Fang, 2009, H. taitungensis Tzeng & Shen, 1982, H. tchangi (Zheng, in Zheng, Chen & Huang, 1982) and H. yaotanensis (Fang, 1931) (see Kottelat, 2012). A survey conducted along the Kaladan River in Mizoram, northeastern India, resulted in the collection of a Hemimyzon species that markedly differs from all other congeners. It is described here as H. indicus.Lalramliana
