| Abstract | Multiplication techniques aiming to reduce time for plantlet production and increasethe number of plantlets from mother material of pineapple cv. Phetchaburi has beendeveloped. The experiment has been conducted at Phetchaburi Agricultural Research andDevelopment Center during 2011-2013 in 50% shading nursery and infield plots. In nurseryexperiment, 3 methods of cutting; crown leaf budding, sucker splitting and stem splittingwere employed with 5 replications in RCB designed. For field experiment, there were 2treatments i.e. apex destruction and young flower removal. The result of nurseryexperiment showed that after 3 months there were more plantlets produced from crownleave than from sucker cutting or stem cutting. However, the height of the plantlets waslower in crown leave than the other two methods. Duration in the nursery beforetransferring to the field was 8-11 months for all three methods. First time production costfor sucker and stem cutting was 313,141 and 247,621 baht/rai whereas production costper plantlet was 4.52 and 1.53 baht respectively. The cost in following production reducedto 187,012 and 121,492 baht/rai and cost per plantlet was 2.70 and 0.75 baht respectively.In the field, two destruction methods were applied to pineapple plants at 5 months afterplanting. The result showed that destruction at meristermatic apex produced moreplantlets while the height and weight werealso greater than the removal of theflowers. Planting time to harvesting ofplantlets of both methods was 14 months.Production cost and cost per plantlet ofmethod 1 and 2 were 136,000 and 96,000bath/rai and 0.85 and 1.09 baht respectively. |
