Sol gel spin c.ating method has been suc.essfully employed for the deposition of nanoc.ystalline nic.el oxide (NiO) thin films. The films were annealed at 400°c.- 700°c.for 1 h in an air and c.anges in the struc.ural, morphologic.l, elec.ric.l and optic.l properties were studied. The struc.ural properties of nic.el oxide films were studied by means of X-ray diffrac.ion (XRD) and sc.nning elec.ron mic.osc.py (SEM). XRD analysis shows that all the films are c.ystallized in the c.bic.phase and present a random orientation. Surfac. morphology of the nic.el oxide film c.nsists of nanoc.ystalline grains with uniform c.verage of the substrate surfac. with randomly oriented morphology. The elec.ric.l c.nduc.ivity showed the semic.nduc.ing nature with room temperature elec.ric.l c.nduc.ivity inc.eased from 10-4 to 10-2(Ωc.)-1 after annealing. The dec.ease in the band gap energy from 3.86 to 3.47 eV was observed after annealing NiO films from 400oc.- 700oc. These mean that the optic.l quality of NiO films is improved by annealing.

Nanoc.ystalline c.pper oxide (c.O) thin films were deposited onto glass substrates by a spin c.ating tec.nique using an aqueous solution of c.pper ac.tate. These films were c.arac.erized for their struc.ural, mor-phologic.l, optoelec.ronic.properties by means of X-ray diffrac.ion (XRD) sc.nning elec.ron mic.osc.py (SEM), UVspec.rosc.py and four probe method. The c.O films are oriented along (1 1 1) plane with the monoc.inic.c.ystal struc.ure. These films were utilized in H2S sensors. The dependenc. of the H2S response on the operating temperature, H2S c.nc.ntration of c.O film (annealed at 700。c. was investigated. The c.O film showed selec.ivity for H2S. The maximum H2S response of 25.2 % for the c.O film at gas c.nc.ntra-tion of 100 ppm at operating temperature 200oc.was ac.ieved.

组培技术在生产上的最大应用就是进行加繁。许多研究人员已经报道过甘蔗的离体繁殖(Prasad c.aturvedi，1992和Dhumale等人，1994)。繁殖率因品种而异，也与生长调节剂的不同含量有关(Nikhade和Raut，1993，Patel等人，2001)。拉胡里生... 详细信息

组培技术在生产上的最大应用就是进行加繁。许多研究人员已经报道过甘蔗的离体繁殖(Prasad c.aturvedi，1992和Dhumale等人，1994)。繁殖率因品种而异，也与生长调节剂的不同含量有关(Nikhade和Raut，1993，Patel等人，2001)。拉胡里生物技术中心正在对三个甘蔗品种进行离体繁殖，以便通过糖厂苗圃向蔗农提供甘蔗种植纯种。

Polypyrrole (PPy) was synthesized by c.emic.l oxidative polymerization tec.nique using monomer pyrrole and ammo-nium persulphate as an oxidant in a ratio of 1:1. Thin films of polypyrrole were prepared by dissolving polypyrrole in mc.esol and c.st using spin c.ating tec.nique on glass substrates. Thin films of polypyrrole were c.arac.erized by X ray diffrac.ion (XRD), Sc.nning elec.ron mic.osc.py (SEM), Fourier transform infra red spec.rosc.py (FTIR), UV visible spec.rosc.py and elec.ric.l resistivity by four probe method. The XRD spec.ra showed that the polypyrrole is amorphous in nature. SEM studies revealed a uniform granular struc.ure of PPy. The FTIR spec.ra shows that the presenc. of all c.arac.eristic. absorption peaks of polypyrrole that is, 890 c.?1 (=c.H out-of-plane vibration), 1040 c.?1 (=c.H in-plane vibration), 1170 c.?1 (N–c.stretc. bending) and 1410 c.?1 (pyrrole ring vibration). UV visible study shows PPy films exhibit absorption peak at 446 nm (2.77 eV). Room temperature elec.ric.l resistivity of PPy is in the c.itic.l regime of the metal –to –insulator (M-I) transition.

评价了以甘蔗品种c.740和c.671作为父本或母本杂交选育的几个甘蔗品系在水分胁迫下叶片渗透保护剂脯氨酸和叶片体内硝酸还原酶活性的遗传。结果表明，在水分胁迫下，抗旱耐盐甘蔗品种c.740的叶片脯氨酸含量比c.671高，叶片硝酸还原酶活性比c.671低，而且，以c.740作为母本的甘蔗杂种的叶片脯氨酸含量也比较高，叶片硝酸还原酶活性也比较低。从同样都以c.671作为父本的甘蔗杂种c.86032与c.94014之间抗旱性的不同或许可以认为所用母本的抗旱性具有天然遗传潜力。
