Evaluation of Brassica genotypes for resistance to shatter. I. Development of a laboratory test
SummaryA new test procedure for measuring shatter-resistance of siliquae of Brassica spp. is described. A siliqua with its proximal end clamped is loaded as a cantilever in a testing machine. TheExpand

Anatomical Basis of Shatter-resistance in the Oilseed Brassicas
Anatomical features of the siliqua valve and suture were studied in 13 Brassica accessions representing B. napus, B. campestris and B, juncea in order to investigate the basis of shatter-resistanceExpand

PENDULUM TEST FOR EVALUATION OF THE RUPTURE STRENGTH OF SEED PODS
A small impact pendulum was developed to measure the shatter resistance of seed pods. While clamped by their stems, the pods are hit by the rigid pendulum; the rupture energy is derived from theExpand

Measurement of the shear and tensile fracture properties of leaves of pasture grasses
The shear fracture properties of leaves of pasture grasses were measured using a shearing device consisting of 2 blades at fixed angles. The mechanics of the shearing process were examined with bothExpand

Evaluation of Brassica genotypes for resistance to shatter. II. Variation in siliqua strengh within and between accessions
SummaryWithin-plant variation in strength of the siliquae, studied in seven Brassica accessions, appears to be mostly associated with variation in size, rather than the position of the siliquae inExpand

Seasonal changes and the effect of temperature and leaf moisture content on intrinsic shear strength of leaves of pasture grasses
The intrinsic shear strength of leaves of 6 temperate pasture grasses was measured using a guillotine. The intrinsic shear strength of the leaves was represented as the force required to shear a leafExpand

Intrinsic shear strength of leaves of pasture grasses and legumes
The intrinsic shear strength of leaves of pasture grasses and legumes was compared. Intrinsic shear strength is calculated as the force required to shear a leaf, divided by the length of the cuttingExpand

The effects of temperature on the retention and denaturation of protein in lucerne leaves subjected to mechanical dewatering
The effects of pretreatment temperature on the retention and denaturation of protein were studied in relation to moisture removal from lucerne forage subjected to mechanical pressing. Leaf samplesExpand

Aerodynamic properties of threshed wheat materials
Abstract The terminal velocities of the straw and of the various particles which make up the head of Olympic wheat were measured by the floating and distance-time techniques. The expected ranges ofExpand
