Field microplot experiments were conducted from 1995 to 1998 to determine the relationship between fresh shoot weight of stalk-cut broadleaf and shade-grown cigar wrapper tobacco types (Nicotiana tabacum L.) and initial density of Globodera tabacum tabacum second stage juveniles (J2) per cm(3) soil. Total shoot weight was negatively correlated with initial nematode densities of 12.3 to 747.3 J2...

Epitrix hirtipennis (Melsheimer, 1847) (Coleoptera: Chrysomelidae: Galerucinae: Alticini), a leaf beetle native to North America, is recorded for the first time from Hungary. Several specimens were found on tobacco (Nicotiana tabacum L.) plantations in eastern and central parts of country. Its life cycle importance as pest are briefly discussed.

Ethylene is a plant hormone that influences many aspects of plant growth and development (10). The biosynthetic pathway of ethylene production in higher plants is well defined. The rate-limiting step in this pathway is the reaction catalyzed by ACC' synthase (S-adenosyl-L-methionine methyl-thioadenosine-lyase, EC 4.4.1.4), which converts Sadenosyl-L-methionine to ACC. Tobacco (Nicotiana tabacum...

This paper is the third and last instalment of our project of computation of the low-degree unramified cohomology of quadrics. As in the previous papers [15] and [16], we denote by η X the map H(F,Q/Z(n− 1))→ H nr(F (X)/F,Q/Z(n− 1)) for a smooth, projective quadric X defined over a field F of characteristic 6= 2. Recall that in these papers we proved that Ker η X is generated by symbols for n ≤...

tobacco (nicotiana tabacum l.) is an important industrial crop and its seeds contain significant amounts of oil. the extraction of oil components using solvent at high pressure, or supercritical fluid (scf), has received much attention. in the present study, statistical analyses showed that the average extraction yield of seed oil of five tobacco varieties using sfe was 9.33%, which was higher ...
