The study of the Suitable Aging of Syzygium cumini (L.) Skeels for Promoting Growth of Phlebopus portentosus (Berk. and Broome) Boedijn under Greenhouse Conditions

Abstract

The study of the suitable aging of Syzygium cumini (L.) Skeels for the growth of Phlebopus portentosus (Berk. and Broome) Boedijn under greenhouse conditions by transplanting mycelium of P. portentosus into seedlings aged for 1, 3, 5, 7 and 9 months. On 1 month after transplanting the data was collected to evaluate the stem height, stem diameter (diameter at the root neck level), biomass of the aboveground part (dry weight of leaves and stems), biomass of the underground part (root dry weight), number of branched roots, root length, number of leaves and percentage of ectomycorrhiza root formation. The results showed that S. cumini seedlings at 7 months were the optimum age for mycelium transplantation and were height seedling and stem diameter at root neck level had significantly different (P≤0.05) were 21.32±1.53 and 1.35±0.09 cm respectively. The number of leaves, root length, biomass of the aboveground part and underground part were 22±1.00 leaves, 645.36±24 mm, 5.2±0.31 g and 2.9±0.74 g respectively. While the percentage of root formation ectomycorrhiza most common when transplanting P. portentosus to 3-month-old seedlings. Based on this research was information to farmer and interested person for selected optimum age of plants host seedling to success of produce P. portentosus in the future.
