Abstract
The transition from vegetative growth to flowering is one of the most important periods of ontogenesis. Changes in apices of mangosteen Garcinia mangostana L. and rambutan Nephelium lappaceum L. were studied at Chanthaburi Horticultural Research Centre in Chanthaburi. Also strawberry Fragaria ananassa Duch. were studied at Doi Tung in Chiangrai. The samples were taken every fortnight and were dissected under a stereomicroscope magnified 10 to 64 times. Vegetative apices of all crops studied were seen as flattening apices. These were rounded and flattened in mangosteen lobed and flattened in rambutan and non-swelling with last trifoliate leaf in strawberry. The first evidence of flower initiation appeared as an enlargement and raising of the apices. Then the sepal development was noted. As sepals grew petal initiation was seen. When the sepals began to enclose the bud it was about the same time that the pistils and/or stamens began to develop. The minimum temperature was the most important factor and was higWy correlated with changes in apices of all crops studied.
