Abstract
First sepal, numbered 1 in Fig. 1, developed to the opposite side from the terminal leaf on the main shoot of tomato plants with left-handed phyllotactic spirals. Second, 3rd, 4th and 5th sepals, numbered 2, 3, 4 and 5 in Fig. 1, respectively, developed in anticlockwise direction. The reverse was true on plants with right-handed phyllotactic spirals.
Although the developing order in 5 petals, 5 stamens and 2 carpels could not be determined, the same orderlines as in 5 sepals was presumed.
The main vascular connections observed in the fruits of tomato and pepper fruit were as follows: (1) peduncle to receptacle to sepal, (2) peduncle to receptacle to petal, (3) peduncle to receptacle to stamen, (4) peduncle to receptacle to pericarp to fruit distal end, (5) peduncle to receptacle to fruit axis to placenta to seed.
The direction of vascular bundles in each part was as follows: centrifugal in the sepal, petal and stamen, and acropetal in the pericarp and fruit axis. Vascular bundles in the pericarp were situated on the center of each carpel, and those in the fruit axis were on the border of each carpel.
The basic number of vascular bundles in each part was 1 each in the sepal, petal and stamen. In pericarp and fruit axis, the number of vascular bundles was as many as the number of carpels.
