Efecto de algunos factores del ambiente in vitro en la multiplicacion del name (Dioscorea alata L.) II. Portador del nitrogeno


, : Efecto de algunos factores del ambiente in vitro en la multiplicacion del name (Dioscorea alata L.) II. Portador del nitrogeno. Alimentaria 38(326): 115-118

The effect of the ammonium and potassium nitrate on nodal segments micropropagation of yam was analysed. The evaluated variables were bud number, shoot length, extended totally leaves number and roots number. A totally randomized design and bifactorial variance analysis was used. The mean analysis was carried out by tendencies curved.

Tuberculous involvement of the oesophagus is a rare disease. Even if it is suspected, diagnosis is often difficult, though dysphagia and chest pain are the most common symptoms without any other specific signs of tuberculosis. The diagnosis is bas...

Stormwater runoff has resulted in heavy metal contamination throughout much of the Port Jackson estuary, Sydney (New South Wales, Australia).

We previously demonstrated that repeated application of 2,4,6-trinitro-1-chlorobenzene resulted in a site-restricted shift in the time course of Ag-specific hypersensitivity responses from a typical delayed-type to an early-type response. Here we...

Thirty-two vanB2 Enterococcus faecium isolates were found to harbor Tn5382. Twenty-four isolates had a 1,419-bp sequence inserted within the open reading frame (ORF) C of Tn5382. This 1,419-bp sequence contained a 638-bp ORF with a 72% amino acid...

Growth hormone (GH) and IGF-I have receptors within the corpus luteum (CL) and stimulate CL function. Our objective was to investigate the effects of GH, prolactin (PRL), IGF-I, IGF-II, LH, and FSH on progesterone secretion by porcine luteal cells...

The ratio of early transmitral velocity to tissue Doppler mitral annular early diastolic velocity (E/Ea) has been correlated with pulmonary capillary wedge pressure (PCWP) in a wide variety of cardiac conditions. The objective of this study was to...

Haragsim, O., 1977: Nectar production of cucumber varieties Parifin and Znojmia, and the activity of bees in pollinating their flowers. The morphology and anatomy of the nectaries of the Parifin variety, which is widely grown in Czechoslovakia, were studied. The nectar contained sucrose, glucose and fructose, with a total sugar content of about 30%. The variety Znojmia produced le...
