Spatially heterogeneous distribution of interspecific competitors and intraspecific aggregation of offspring ramets may affect the growth and size structure of clonal plant populations, but these have been rarely studied. We conducted a greenhouse experiment in which we grew a population of eight offspring ramets (plants) of the stoloniferous clonal plant Hydrocotyle vulgaris aggregately or seg...

Barnyard grass (var. onyzicela) showed no apparent damage in paddy fields where hopperburn occurred by a large number of NL lugens. The causes of barnyard grass resistance to this inscct and thc insect-host interrelations of threc species of planthoppers (N. Iugens, L. striatellus and S. farctfera) between rice plant and barnyard grass were studicd. Nymphs of IV. Iugens could not grow by feedin...

in the present study, the effects of two arbuscular mycorrhizal fungi, glomus mosseae andglomus intraradices, alone and in combination, on the growth parameters, chlorophyll and the root-rot disease of pea (pisum sativum) caused by fusarium solani f.sp. pisi were evaluated under greenhouse conditions. eight different treatments in four replications were designed in randomized blocks. compared w...

The present study was carried out to evaluate the effect of Mr. Trivedi’s biofield energy treatment on mustard (Brassica juncea) and chick pea (Cicer arietinum) for their growth, yield, and yield attributes. Both the samples were divided into two groups. One group was remained as untreated and coded as control, while the other group (both seed and plot) was subjected to Mr. Trivedi’s biofield e...

Smýkal P. (2014): Pea (Pisum sativum L.) in biology prior and after Mendel’s discovery. Czech. J. Genet. Plant Breed., 50: 52–64. Pea (Pisum sativum L.) has been extensively used in early hybridization studies and it was the model organism of choice for Mendel’s discovery of the laws of inheritance, making pea part of the foundation of modern genetics. Pea has also been used as model for experi...

Identifying key yield components can help establish better crop management strategies to increase crop yield. The present research was conducted in south-western Saskatchewan in 1999 and 2000 to determine the interrelationships among various yield components and their direct and indirect effects of each component on seed yield of field pea (Pisum sativum L.). The semi-leafless cultivar Carrera ...

Legumes are a rich source of valuable nutrients thus represent important component in human and animal nutrition. The most often limiting factor legume production is the presence seed pests, such as bean weevil Acanthoscelides obtectus (Say, 1831). This work tested suitability three different species (common bean, faba grass pea), with growing interest diet, for development weevil, aiming to pr...

Introduction Beach pea (Lathyrus maritimus [L.] Bigel.), a potential cold-climate circumpolar legume crop, naturally grows along the shorelines of Newfoundland, Canada. It is perennial and persistent for many years, and is resistant to drought and frost. It forms large continuous stands by rhizomes and has prolific seed production. Sometimes, the vegetative parts of beach pea are used as fodder...
