PERTUMBUHAN VEGETATIF DAN GENERATIF Stachytarpeta jamaicensis(L.) Vahl
ABSTRACT: Stachytarpeta jamaicensis
belongs to family
Verbenaceae believed to
cure malaria, scabies,
headaches,stimulant, tonic, expectorant and fever. The research aims to
determine vegetative and generative growth of
Stachytarpeta jamaicensis was conducted in Purwodadi Botanic Garden in
October 2012 - June 2013
by observing 9 plants grouped in 3 replications. Seedlings with 6-12
leaves were planted in polybags with diameter 13 cm, height 16 cm filled with
soil media ‘katel’ (soil stream sediment).
The plants placed
outside the glass
house with light
penetration about 20%.
Growth observations conducted every
week to high,
leaf number, shoot/branch
number, spike number,
spike length, early
flowering and fruit maturity of the plants. The results
showed that the plant height, the leaf number, the shoot and branch and the
spik s number of the plants was increasing linearly up to the age of 90 days
after planting (DAP). Early and late flowering varied each 20-40 DAP and 69-83 DAP. The length of spikes
growth following the sigmoid curve and the
fruits mature at the age of 38 days after
fertilization.
