Medicinal and aromatic plants farming under drought conditions

Drought stress is especially important in countries where crop agriculture is essentially rain-fed. Drought stress causes an increase in solute concentration in the environment, leading to an osmotic flow of water out of plant cells. This in turn causes the solute concentration inside plant cells to increase, thus lowering water potential and disrupting membranes along with essential processes like photosynthesis. These...

In vitro propagation of white-flower mutant of Rhynchostylis gigantea (Lindl.) Ridl. through immature seed-derived protocorm-like bodies

Rapid in vitro propagation of white-flower mutant of Rhynchostylis gigantea (Lindl.) Ridl. was established for the first time through 4 month old immature seed-derived protocorm-like bodies (PLBs). 75% of PLBs developed from immature seeds cultured on half-strength MS medium with 0.05 mg·l-1 6-BA and 0.2 mg·l-1 NAA within 70 days upon transfer to MS medium with...
