Corn-stalk lodging and borer damage as influenced by varying corn densitiesand planting geometry with soybean (Glycine max. L. Merrill)
stalk lodging borer damage planting densities planting geometry soybean
2008/11/26
Cultural practices which increase the amount of insect pressure can also increase the amount of lodging that occurs in the corn crop. Studies were therefore carried out, in the late cropping seasons ...
Genetic analysis of morphological and physical stem characteristics determining lodging resistance in two- and six-rowed barley (Hordeum vulgare L.) lines
Hordeum vulgare doubled haploids Young’s modulus lodging

The study presents the results of genetic analysis of selected morphological and physical stem characteristics determining lodging resistance in doubled haploid (DH) lines of spring barley produced fr...
Genetic control of morphological and physical characteristics determining resistance to lodging in barley (Hordeum vulgare L.)
Hordeum vulgare L. DH lines genetic para- meters heritability resistance to lodging Young's modulus
2008/11/18
In the present paper evaluation of the effects of gene action on the properties determining resistance to lodging in barley is presented. Genetic analysis was performed on the data for doubled haplo...
Genotype-environment interaction of barley DH lines in terms of morphological and physical traits of the stem and the degree of lodging
Hordeum vulgare G x E interaction DH lines Young� s modulus lodging
2008/11/18
The study presents results of investigations concerning the effect of environmental conditions on the morphological and physical traits of the stalk and the degree of lodging in barley (Hordeum vulgar...
Significance of geometrical and physical features for genetic analysis of trials determining lodging resistance
Hordeum vulgare L. genetic parameters lodging resistance Young`s modulus
2008/11/12
In the paper 28 lines of doubled haploids (DH) produced from F1 hybrids Aramir x EP79 were investigated under field conditions. Lodging degree was estimated in the field applying a 9-grade scale (whe...
The effect of sowing density on the lodging and mechanical properties of rape stalks
rigidity dynamic shearing energy stem cross section area
2008/11/10
In this study, the mechanical properties of rape stalks are expressed by means of stalk rigidity determined in bending, and by means of dynamic shearing energy per unit of stalk cross section area. Ex...
