tissue culture methods provide tools to supplement traditional methods for collection, propagation and preservation of endangered plant species. in this study, in vitro propagation of diaphanoptera khorasanica rech.f., a rare and threatened plant species with limited distribution range and population was investigated. this species has a potential as an ornamental plant. single node explants wer...

A micropropagation protocol was developed which may assist in the safeguarding and augmentation of dwindling natural populations of Clinopodium odorum (Griseb.) Harley, a critically and endangered medicinal plant. Factors affecting culture initiation bud sprouting and growth, rooting, and acclimatization were studied, using nodal segments of in vitro germinated seedling as primary explants on s...

In vitro evaluations of salinity (NaCI) effects on three potato cultivars (Atlanta, Shepody and Shilbilaty ) were investigated with five NaCI levels ( 0, 25, 50, 75 and100 mM) by using single node explants. Significant differences were noticed among the cultivars followed by different NaCl levels. Salinity stress gradually depressed plant growth and root development with increased NaCl concentr...

The Dendrobium Orchid Gatton Sunray is a hybrid orchid of pulchellum × illustre . A study was aimed to find the best type medium and banana for multiplication Protocorm-Like Bodies (PLBs) this orchid. This research conducted from February September 2020 at Plant Tissue Culture Laboratory, Faculty Agriculture, University Bengkulu. Treatments included media cultivar ripe fruit, added as source or...

The current research work was carried out to verify the role of AgNO3 silver nitrate in germination and growth seedlings Leucaena leucocephala trees demonstrate effects on indicators such as stem height, root length, number vegetative branches leaves per seedling, well induction callus from leaf explant, In presence absence MS culture media. As different concentrations were used, continuous tha...

microbial cells are producers of natural polymers present in plant cells. production of pullulan (an extracellular microbial polysaccharide) by aureobasidium pullularia pullulans (p. pullulans) was studied under fermentation conditions, and kinetic parameters were determined. pullulan formation obeyed a growth and non-growth associated term. phb (polyhydroxybutyrates) an intracellular biopolyme...

to study the effects of nitrogen on tomato plant growth and the possibility of reducing nitrogen in drainage water, two nutrient solutions (complete nutrient solution (n+) and nutrient solution with a 30% decrease in n concentration (n-)) along with and three culture media (perlite, a mixture of perlite and nh4- enriched zeolite and finally a mixture of perlite and raw zeolite) were employed fo...
