The somatic regeneration of maize depends on its genotypes, so improving variety with modern biotechnology is severely restricted. Locating the quantitative trait loci (QTLs) associated important for breeding elite inbred lines that undergo genetic transformations. Here, by crossing high-regeneration line H99 and non-regeneration Fr993, an F2 population F2:3 F2:4 families were constructed. Imma...

Sunflower (Helianthus annuus) is a crop of increasing importance as source seed oil and proteins; nonetheless, the number studies on sunflower tissue culture somewhat limited. The development competent in vitro direct organogenesis protocol involves important basic steps regeneration. In our study, chemically sterilized seeds were planted induction media, 52.54 % germination efficiency was foun...

Background: Monovarietal cultivation of cotton plant allowed the genetic erosion for traditional varieties that proceed essential traits mainly involved in breeding. These need to be preserved future used. This study aims evaluate effect gibberellic acid on seed germination and Benzylaminopurin (BAP), Kinetin (KIN), α-naphthalene acetic (NAA) activated charcoal (CA) seedlings growth obtained fr...

Epiphyllous plantlets develop on leaves of Bryophyllum marnierianum when they are excised from the plant. Shortly after leaf excision, plantlet shoots develop from primordia located near the leaf margin. After the shoots have enlarged for several days, roots appear at their base. In this investigation, factors regulating plantlet root development were studied. The auxin transport inhibitor 2,3,...

Factors like slow and seasonal multiplication and infection with pathogens have constrained the use of conventional plant propagation methods, thus lead to development of new and novel methods of propagation like in vitro multiplication which ensures the production of virus and disease free elite planting material in large numbers. In the present work, in vitro regeneration protocol has been st...
