this research investigate the effects of different concentrations of salt: 0, 75, 100, 150 (mm nacl) and concentration of 0.05 mm gibberellic acid and 5µm salicylic acid on the content of proline and a, b chlorophylls of canola (hayola 401 and rgs). the results showed that with increasing in the amount of salinity in both chlorophylls decreased and the amount of decrease in chlorophyll b was mo...

The effects of breathing CO continuously at high altitude on the mean electrical axis of the heart, hematocrit ratio and body weight were studied in laboratory rats. Laboratory rats were exposed for 6 weeks to: 100 or 500 ppm CO; 15,000 feet stimulated high altitude (SHA); or 100 or 500 ppm CO at SHA. SHA decreased body weight significantly; CO and CO-SHA interaction had no significant effect o...

BACKGROUND Ischemia-reperfusion injury (IRI) is a major cause of cardiac damage following various pathological processes. Gaseous hydrogen sulfide (H2S) is protective during IRI by inducing a hypometabolic state in mice which is associated with anti-apoptotic, anti-inflammatory and antioxidant properties. We investigated whether gaseous H2S administration is protective in cardiac IRI and whethe...

アイリスは低温であっても乾式貯蔵により開花不良が発生するとともに，観賞期間が短いことが問題となっている．一方，出荷日を調整するために貯蔵は不可欠である．開花不良を改善するgibberellin（GA3）は薬剤が高価であり，これを含む品質保持剤の導入は生産現場において限定的である．そこで，GA3の代替として，GA3よりも安価で開花不良の改善効果について報告のあるsilver thio-sulfate complex（STS）およびSTSとbenzyladenine（BA）の組み合わせが開花不良と観賞期間に及ぼす効果について調査した．STSは，5°C・5日間の低温乾式貯蔵前の処理により，正常開花率は対照（水道水）区の0％に対し60％となり花被片展開を促進したが，その効果はGA3の100％より低かった．また，STSとGA3は観賞期間を4.0日から5.0日に延長したが，その効果はBAの5.8...

EFFECTS OF CARBON DIOXIDE ENRICHMENT AND IRRADIANCE ON EX VITRO ROOTING, ACCLIMATIZATION AND SUBSEQUENT GROWTH OF MICROPROPAGATED APPLE AND BLUEBERRY. Marvin Pritts and Dorcas Isuta*, Cornell University, Fruit and Vegetable Science Department. 134A Plant Science Building, Ithaca, NY 14850 Previous findings reveal that rooting and acclimatization of apple and blueberry plants is often difficult ...

Laboratory bioassay of the essential oil extracted from an indigenous plant, Ipomoea cairica, commonly known as 'Railway creeper', was carried out against the larvae of four vector species of mosquitoes in order to evaluate its mosquito larvicidal effect. Bioassay test revealed that the essential oil of the plant possess remarkable larvicidal properties as it could induce 100% mortality in the ...

Crop field soil collected from Sambalpur University campus of Odisha and treated with various fluoride concentrations was used to raise selected local crops. Background concentration of total and leachable fluoride content in soil was 95.19 and 8.89 ppm respectively. At the time of harvest of the crops, the total fluoride content was found to decrease and leachable fluoride content was found to...

Essential oils of seven Moroccan Labiatae were chemically analysed by GC-MS and evaluated for their in vitro antifungal activity against Botrytis cinerea. Among them, Origanum compactum and Thymus glandulosus greatly inhibited the growth of the mycelium. The inhibition of Botrytis cinerea was 100% for both oils at 100 ppm, while the IC(50)s were 35.1 and 79.2 ppm, respectively. Mentha pulegium ...
