روياندن بذر و تفاوت در توانمندي هاي نونهالي در دو گونه از جنس مورينگا

Seed germinating and the differences between seedling characteristics of two Moringa species

Moringa peregrina is a valuable tree with economical and medicinal values as well as environmental importance. Due to several reasons such as seed harvesting, the species lacks enough regeneration in its habitats in the country. There are several restrictions on seedling production of the species for which optimizing seedling production is of great importance. Seed germination and seedling production of two species of moringa named M. oleifera and M peregrina were investigated on three different media, MS without sucrose, sterile mixture of pit and vermiculite and normal mixture of pit and vermiculite based on completely randomized design. Characteristics such as main root and hypocotyls length were recorded and analyzed after seed germination and seedling growth. In spite of a long period of seed sowing, the seeds sown in pots and magentas did not germinate enough but sowing the uncoated seeds on MS medium resulted in a good seed germination and seedling growth. In other words, this method may be easily used for old seed reclamation and seedling production on the two species. There were significant differences on early vegetative growth and growth speed of the two species based on the plantlets grown on the MS medium, which are discussed in the text.
