“…The study also showed that the panicles that differentiated from larger ADs differentiated a larger number of PBs. Several studies have indicated that the final size of or the number of aboveground organs in rice correlated with the size of AD at the time of their differentiation (Yamazaki, 1963a;Fukushima, 1999) . Yamazaki ( 1963a) showed that the final size of rice leaves on a culm was larger, the higher the node position, and found that the final size of the leaf was proportional to the AD size at the time of its differentiation.…”

“…These serial sections were then used for measurements of the diameter and height of AD as well as for the determination of the developmental stage of the panicle. The growth of AD through successive plastochrons can be shown as a saw-toothed line (Yamazaki, 1963a;Lyndon, 1998). At the end of each plastochron, the formation of a new primordium results in an abrupt reduction in the size of the AD, from maximal to minimal.…”

“…In this experiment, plant age in leaf number was measured for all plants and we collected samples uniform in plant age as much as possible. The synchrony between leaf emergence and the differentiation of a leaf primordium (Yamazaki, 1963a) was also used to obtain uniform samples. However, because of the restriction in the numbers of pots and plants, uniformity of the sections was not satisfactory to obtain sufficiently precise data to analyze the relationship between AD size and morphological characters of panicle components.…”

“…3. Measurement of AD size and morphological characters of panicle components The base diameter and the height of ADs at the late vegetative stage and PI stage were measured according to the method of Yamazaki (1963a). The definitions of the diameter and the height of AD in this study are shown schematically in Fig.…”

“…The diameter of the AD during the vegetative stage increases with increasing plant age in leaf number, and the diameter at the time of the differentiation of a leaf primordium positively correlated with the width of the corresponding fully-expanded leaf blade (Yamazaki, 1963a). Rice plants under sparse planting conditions or sufficient nitrogen conditions had a large vegetative AD (Yamazaki, 1963b), and a larger number of spikelets per panicle.…”

Main-stem apical development and its inter-relations with other aspects of plant morphology were studied in seven field crops of winter wheat (Triticum aestivum L., cv. Maris Huntsman).Apical primordia were produced slowly in autumn and winter, then faster in spring as the weather became warmer. Spikelets were initiated about three times as fast as leaves. Leaf initiation ended at around the time that tiller bud initiation stopped. Apical dome length and diameter both increased during leaf initiation, reached a maximum at double ridges and then decreased. Double ridges appeared when very nearly 50 % (range 49-52 %) of the final number of spikelets was present. Spikelet initiation ended a few days after the first florets were initiated and when stem extension began, but usually before the stem apex rose above the soil. Floret initiation finished at about the time that the flag leaf appeared. Throughout tillering there was a strong association between tiller emergence and leaf appearance.There were considerable differences between seasons in the timing of developmental events on the apices of main stems, but a difference in sowing date of 5 months was reduced to little more than 1 month in the timing of anthesis and the maximum numbers of organs varied only slightly with sowing date.
