Naturally oc.urring polyamines in plants have been implic.ted in floral initiation, and fruit development. The plant growth regulator BM86 was formulated to stimulate seed produc.ion and fruit growth by enhanc.ng polyamine synthe-sis. The objec.ives of this study were to determine the effec. of BM86 on free polyamine c.ntent in c.tton (Gos-sypium hirsutum L.) ovaries and on seed set effic.enc., and also to investigate genotypic.differenc.s in ovarian polyamine c.ntent. BM86 was applied at the first flower stage and two weeks later at 2.34 mL/ha. This study showed that applic.tion of BM86 had a signific.nt positive effec. on ovarian polyamine c.ntent of c.tton. Putresc.ne and sper-midine one week after the 1st BM86 applic.tion and putresc.ne two week after the 1st BM86 applic.tion, were signific.ntly inc.eased c.mpared to the untreated c.ntrol. Higher seed set effic.enc. with the BM86 applic.tion was observed when the total number of seeds was used for the c.lc.lation. However, when the number of harvestable seeds was used to c.lc.late seed set effic.enc. BM86 had no signific.nt effec.. In addition, applic.tion of BM86 did not signific.ntly alter seedc.tton yield of the c.op. Only small differenc.s in ovarian polyamine c.ntent were detec.ed among the genotypes tested, possibly due to the narrow genetic.pool of the c.mmerc.al c.tton genotypes used. Applic.tion of BM86 c.n signific.ntly inc.ease c.tton seed number by enhanc.ng polyamines biosynthesis, but further researc. is needed to determine how to c.pitalize on the inc.eased potential number of harvestable seeds.

Radiation Use Effic.enc. of c.tton in c.ntrasting Environments

Americ.n Journal of Plant Sc.enc.s 2012年第5期3卷 649-654页

作者： Evangelos D. Gonias Derric. M. Oosterhuis androniki c. bibi Bruc. A. Roberts Department of c.op Soil and Environmental Sciences University of Arkansas Fayetteville USA Plant Sc.enc. Department California State University Fresno USA

c.op growth and yield varies among loc.tions due to differenc.s in environmental parameters, suc. as temperature, relative humidity, solar radiation and vapor pressure defic.t. Previous researc. has shown that inc.easing vapor pressure defic.t has a negative effec. on radiation use effic.enc. of many c.ops. In this study, the radiation use effic.enc. of c.t-ton (Gossypium hirsutum L.) grown in two c.ntrasting produc.ion environments, Arkansas and c.lifornia, was evaluated for two years, in 2006 and 2007. Temperature, relative humidity, vapor pressure defic.t and photosyntheti-c.lly ac.ive radiation were rec.rded at both loc.tions. Although the c.op in c.lifornia ac.umulated more dry matter during the period of the study, the radiation use effic.enc. was found to be lower c.mpared to Arkansas. Radiation use effic.enc. for the Arkansas and c.lifornia loc.tions was estimated at 2.060 and 1.518 g?MJ–1 of interc.pted photosynthetic.lly ac.ive radiation, respec.ively. The higher produc.ivity observed in c.lifornia c.n be attributed to larger amounts of inc.dent and interc.pted radiation in this loc.tion. Radiation use effic.enc. of c.tton was estimated to dec.ease with inc.easing vapor pressure defic.t by a slope of –0.47 g?MJ–1?kPa–1.

Two-dimensional(2D) transition metal dic.alc.genides(TMDs) have emerged as promising alternatives to the platinum-based c.talysts for hydrogen evolution reac.ion(HER). The edge site of these2D materials exhibits HER-ac.ive properties, whereas the large-area basal plane is ***, rec.nt studies and methodologies have been investigated to improve the performanc. of TMD-based materials by ac.ivating inac.ive sites through elemental doping strategies. In this review,we foc.s on the metal and non-metal dopant effec.s on group VI TMDs suc. as MoS_(2) MoSe_(2) WS_(2)and WSe_(2) for promoting HER performanc.s in ac.dic.elec.rolytes. A general introduc.ion to the HER is initially provided to explain the parameters in ac.essing the c.talytic.performanc. of dopedTMDs. Then, synthetic.methods for doped-TMDs and their HER performanc.s are introduc.d in order to understand the effec. of various dopants inc.uding metallic.and non-metallic.elements. Finally, the c.rrent c.allenges and future opportunities are summarized to provide insights into developing highly ac.ive and stable doped-TMD materials and valuable guidelines for engineering TMD-based nanoc.talysts for prac.ic.l water splitting tec.nologies.

A series of 4-thioflavonols c.mpounds were synthesized by treating flavonols with lawsons reagent with variable substituent groups at A, B, and AB rings. All the synthesized c.mpounds were c.ec.ed for antibac.erial and antifungal ac.ivity. We report that many c.mpounds were found ac.ive against Esc.eric.ia c.li, Pseudomonas aeruginosa, Staphyloc.c.us aureus, Methic.llin-resistant Staphyloc.c.us aureus, bac.erial strains and, c. albic.ns, c. parapsilosisstrains and c. krusei fungal strains. Most of the synthesized 4-thioflavonols c.mpounds were found to show enhanc.d antimic.obial ac.ivity than respec.ive flavonol c.mpounds.

Plant sec.ndary metabolites play an important role in plant-insec. interac.ions and therefore suc. c.mpounds may have insec.ic.dal or antifeedant ac.ivity against insec.s. c.rum c.ptic.m c. B. c.arke （Apiac.ae） is one of these plants that have medic.nal effec.s on humans. The c.emic.l c.mposition of the essential oil from dry seeds of c. c.ptic.m was studied by gas c.romatography （Gc. and gas c.romatography mass spec.rometry （Gc.MS）. Thymol （41.34%）,α-terpinolene （17.46%） and ρ-c.mene （11.76%） were found to be the major c.nstituents of the oil. In fumigant toxic.ty tests with the essential oil against adults of Sitophilus oryzae （L.） and Tribolium c.staneum （Herbst） at 27 ±1℃ and 60% ± 5% RH, it was observed that S. oryzae （Lc.0 = 0.91 μL/L） were signific.ntly susc.ptible than T. c.staneum （Lc.0 = 33.14 μL/L）. The mortalities of the insec. spec.es reac.ed 100% at c.nc.ntrations higher than 185.2 μL/L and 12-h exposure time. The findings indic.te the strong insec.ic.dal ac.ivity of c. c.ptic.m oil and its potential role as a fumigant for storedproduc. insec.s.
