Pathogenic races of the melon-wilt Fusarium in Israel     

D. Netzer  Ch. Weintall 《Phytoparasitica》1979,7(3):203-205

Two races ofFusarium oxysporum f. sp.melonis were identified among 54 isolates of this pathogen, tested on three differential lines of melon. Of the two races, race 0 was the more prevalent, comprising 92.5% of the total number of isolates tested. Race 1 has been encountered so far in one growing area only. The identity of the local races is compared with those defined in France and in two areas of melon-growing in California.  相似文献   

Superovulation beim Rind: Hormonprofile bei Stimulation mit Serum-gonadotropin (PMSG) bzw. hypophysärem FSH*)     

D. Von Schams  Ch. Menzer  E. Schallenberger  B. Hoffmann  A. Prokopp  B. Hahn  R. Hahn 《Reproduction in domestic animals》1979,14(1):11-25

Contents: Superovulation in cattle: Hormonal profdes during superovulation with PMSG or pituitary FSH.: Hormonal profiles for LH, FSH, PMSG, progesterone in peripheral blood and oestrogens in urine during superovulation with PMSG (1500–3100 IU i. m.) or pituitary porcine FSH (5 mg i.m. 2 times daily for 5 days) were evaluated radioimmunologicaly. Two days after the begin of treatment luteolysis was induced by means of 0.5 mg Estrumat® i. m. The experiments were performed with 14 heifers and 2 cows. Blood samples were taken in 6 or 12 h intervals. Preovulatory LH and FSH peaks occurred coinciding with the onset o f oestrus in good responding animals instead of a few hours later, as in weakly responding animals or during normal oestrous cycle. PMSG could be still measured in peripheral blood 10 days after application. Preovulatory gonadotropin peaks are preceded in good responding animals by clear oestrogen peaks contrary t o weak responding ones. Progesterone concentrations of good responding animals increase faster after the preouulatory LH peak and reach higher absolute values compared t o bad responding ones or during normal oestrous cycle. Furthermore there was a clear difference in progesterone values between both stimulation methods. Progesterone concentrations after induction of superovulation with PMSG are significantly higher f o r about the same number of corpora lutea as after stimulation with pituitary FSH. For judgement of the success of stimulation the determination of progesterone can be considered as parameter. From the hormonal profiles no conclusion can be drawn why some animals don't respond to the stimulation.  相似文献

The effects of growth substances and photoperiod on the development of shoot apices of Vitis cultured in vitro     

R. Chée  R.M. Pool 《Scientia Horticulturae》1982,16(1):17-27

‘Rougeon’ grapevines were recovered from shoot apices using in vitro culture. Shoot development from apices 0.5–1 mm in length, which contained 2–4 leaf primordia was obtained with 5 × 10^?6M benzylaminopurine and 5 × 10^?7M naphthaleneacetic acid (NAA) under a 10-hour photoperiod, but not under continuous light, in a 15-hour photoperiod, or in darkness. At least one vigorous shoot was produced by 100% of the cultures.Rooting of these shoots was induced under the same photoperiod with the same basal culture media containing only 10^?7 M NAA. Roots were produced by 91% of the cultures. Zero-, 16- or 24-h photoperiods were ineffective in promoting root development.Rooted plantlets were transferred into soil with 80% of them surviving. The grapevines were allowed to reach an average length of 2 m in a growth chamber before growth conditions were modified to induce dormancy. Vines were planted in a vineyard; after 2 growing-seasons we were unable to distinguish the micropropagated vines from ‘Rougeon’ vines propagated in the standard manner, on the basis of fruit or vegetative morphology.  相似文献   

Relations entre le desséchement de la rafle et Botrytis cinerea sur raisins¹     

par Ch. BRECHBUHLER 《EPPO Bulletin》1982,12(2):29-35

Le dessèchement de la rafle d' origine physiologique et la pourriture pédonculaire due au champignon Botrytis cinerea sont encore trés souvent confondus par les praticiens et techniciens. De ce fait, les differences et analogies dans les symptomes sont discutees. Le dessèchement de la rafle est surtout caractérisé par la date d' apparition des atteintes, dans les 15 jours qui suivent la mi-véraison, et par la présence de nécroses bien localisées, sèches, a contours limites. De nombreux facteurs sont communs. Mais, contrairement à l' opinion encore très répandue, le dessèchement de la rafle ne favorise pas l' installation de B. cinerea. Certaines techniques, telles que l' effeuillage, le traitement a la gibbérelline, l' enlèvement de baies, réduisent les deux maladies. On constate alors un enrichissement en calcium et magnésium de la rafle qui s'accompagne d' un développement des faisceaux libéro-ligneux dans le cas de la gibbérelline. L' importance économique de la pourriture pédonculaire est plus grande; les pertes peuvent s'elever jusqu'a 50–60 % de la récolte contre moins de 25 % par le dessèchement de la rafle. Le traitement des grappes à la véraison, avec un mélange d' un sei magnésien et d' un fongicide de la famille des imides cycliques, est efficace.  相似文献   

Mycoplasma infections in sheep, goats and yaks     

Ch Damdinsurén 《Archiv fuer experimentelle veterinaermedizin》1989,43(5):763-767

Mycoplasmas were isolated from yak calves in Mongolia, the 1st experience worldwide with this species. They were also isolated from pathologically affected sheep and goat lambs. The disease was experimentally reproduced in yak calves as well as in sheep and goat lambs. Clinical manifestations were identical with those recordable from animals with spontaneous outbreak of the disease. This had been for the 1 time ever that a therapy was tested on animals with mycoplasmosis, using water with addition of oligodynamic silver. Something between 95 and 100% of all patients were clinically cured. The experimental vaccine involved was found to offer protection against mycoplasmosis to sheep and goat lambs. Damage association with mycoplasmosis was found to occur 1st in liver, spleen, and lymph nodes and to be subsequently proliferated to lung and other organs. Respiratory mycoplasmosis is the common definition used at present but is not in conformity with the pathological processes involved, as the major role is played by liver damage. Mycoplasmosis in these 3 species, therefore, should better be named mycoplasmosis bovi hepatica.  相似文献
