The requirement for sterility in plant tissue cultures avoidance of dehydration can impose sealing requirements that severely limit the rate of gas exchange in and out of the culture vessel. Conditions within the culture vessel such as the depth of any water cover, the presence of gelling agents, the bulk and porosity of the tissue and the temperature also strongly influence in vitro rates of g...

A plant tissue-based chemiluminescence biosensor for ethanol based on using mushroom (Agaricus bisporus) tissue as the recognition element is proposed in this paper. The principle for ethanol sensing relies on the luminol-potassium hexacyanoferrate(III)-hydrogen peroxide transducer reaction, in which hydrogen peroxide is produced from the ethanol enzymatic catalytic oxidation by oxygen under th...

INTRODUCTION In 1902 Gottleib Haberlandt proposed the idea of growing individual plant cells on artificial medium. While Haberlandt never realized his idea, the 105 years since has seen the concept evolve into a powerful tool utilized throughout the plant sciences. Plant tissue culture broadly refers to growing plant cells, tissues, organs, seeds, or other plant parts in a sterile environment o...

THE transformations which different sugars undergo in plant tissue, independently of the photosynthetic process, are as yet imperfectly understood. There is every reason to assume that all the individual carbohydrates in plant material are capable of conversion into each other, though the experimental evidence at hand is insufficient to warrant definite conclusions in individual cases. This is ...

Plant petioles and stems are hierarchical cellular structures, displaying structural features defined at multiple length scales. The current work focuses on the multi-scale modelling of plant tissue, considering two orders of structural hierarchy, cell wall and tissue. The stiffness of plant tissue is largely governed by the geometry of the tissue cells, the composition of the cell wall and the...

Tissue culture is an in-vitro technique for replicating a plant without introducing the degree of genetic variability inherent in sexual reproduction. Tissue culture has proven commercially important for the replication of ornamental varieties of house plants and is used extensively in research for applications in forestry. Activated carbon (AC) was initially added to tissue culture media in an...

the effect of annona squamosa, lawsonia inermis and their combination with other herbal molluscicides were studied on different enzyme activity in the nervous tissue of lymnaea acuminata. twenty-four hour in vivo exposure to 40% and 80% of 24 h lc50 of plant derived molluscicides and their combination with other molluscicides such as cedrus deodara, azadirachta indica oil, allium sativum, polia...
