Abstract

The invention provides a chemical induction adjusting method for tobacco axillary bud growth and development. The method includes from a tobacco plant budding period to a blooming period, using a prepared axillary bud growth chemical induction regulator to continuously spray entire tobacco plants for three days (once a day), or clamping cotton balls or brush pens dipped with the prepared axillary bud growth chemical induction regulator at 1-10 leaf axil of the tobacco plants from top to bottom; when axillary bud lateral branches grow to be 10-20cm and 1-2 new leaves of the lateral branches are already unfolded, pruning original leaves on the tobacco plants in batches; when the axillary bud lateral branches grow to be 20-30cm and the lateral branches are about to be in the budding period, using a prepared lateral branch blooming chemical induction regulator to continuously spray the entire tobacco plants for three days (once a day). By the method, more axillary buds of paternal tobacco plants are enabled to develop to be lateral branches, and more flowers and pollen are provided for hybrid seed production, so that the objectives of reduction of paternal planting area, lowering of seed production cost and improving of production benefit of tobacco hybrids are achieved.

Description

technical field

[0001] The invention relates to a chemically induced regulation method for the growth and development of crops, in particular to a chemically induced regulation method for the growth and development of tobacco axillary buds. Background technique

[0002] Tobacco is a limited compound cyme. The terminal buds of the tobacco plant, the terminal buds of each flower branch and the side buds of the flower base of each flower are not only differentiated to form a cyme-shaped main inflorescence, but the first, second and third axillary buds immediately below the inflorescence are "established buds". After opening, it gradually develops into cymose side flowering inflorescences from top to bottom. The "adventitious buds" in other leaf axils below the "established buds" are in a dormant state under the influence of apical growth dominance, and only when the inhibition of auxin polar transport formed by the apical meristem is released will the auxin gradually grow from...
