Abstract:

The objection ofthis experiment was to study the changes of contents of CTK, IAA and the ratio of CTK/IAA during heading stage , and to investigate the regulation of endogenous hormones in rice tiller. Exogenous 6-BA and IAA were used to regulate the development of tiller buds, establish the transfer between dormancy and germination, and measure the contents of CTK and IAA in elongated nodes and tiller buds located at the elongated nodes. The exogenous 6-BA Increased the CTK contents in nodes and tiller buds, decreased the IAA content in nodes had little effect in the content of IAA in tiller buds, significantly increased ratios of CTK/IAA in both nodes and tiller buds, and promoted the transfer from dormancy to germination. External IAA after removing panicle decreased CTK contents in nodes and tiller buds, which were maintained at a low level, increased the IAA content in buds, and significantly decreased the ratio of CTK/IAA in nodes and tiller buds, causing the transfer from germination to dormancy. Tiller development is determined by the balance between CTK and IAA, higher CTK/IAA ratio is benefit to the transfer from dormancy to germination, while lower CTK/IAA ratio inhibits the transfer. The ratios of CTK/IAA at 2.62.8 in nodes, 4.85.0 in tiller buds can be considered as the critical exponent of the transfer between dormancy and germination.

Key words: RiceTiller bud, Dormancy and germination, Endogenous hormone balance
