Problems solved by technology

There are many studies on the application of chemical regulation on tobacco, mainly in promoting the development of tobacco plants and regulating the content of tobacco leaves. There are few reports on the application of chemical regulation in tobacco seed production, especially in promoting the growth, flowering and development of axillary buds.

example 1 2012

[0024] Example 1: Axillary bud growth and flowering test induced by chemical regulation of B37, the male parent of Burley tobacco hybrid Eyan No. 1 in 2012.

[0025] In this example, B37, the male parent of the Burley tobacco hybrid Eyan 1, was used as the material, and indole-3-acetic acid (IAA), putrescine (Put), and vitamin E (VE) were selected as the chemical components for the germination and growth of the axillary buds of the tobacco plant. Induction regulators; chlormequat (CCC), 6-benzylaminoadenine (6-BA), spermidine (Spd), and vitamin E (VE) are chemical induction regulators of lateral branch flowering in tobacco plants. The test area is 1 mu, and the conventional production is a control area of ​​1 mu, a total of 2 mu. While the conditioner was applied to the test area, the same amount of water was applied to the control area. The field sampling method is sampling at five points, and 10 plants are taken at each point. After 7 days of applying the axillary bud germi...

example 2 2013

[0042] Example 2: Experiments on the growth and flowering of axillary buds induced by chemical regulation of the male parent K8 of flue-cured tobacco hybrid Jinshennong No. 1 in 2013.

Embodiment 2

[0043] In Example 2, the male parent K8 of flue-cured tobacco hybrid Jinshennong No. 1 was used as the material, and the selected chemical induction regulator and test method were the same as in Example 1. The test area is 2 mu, and the conventional production is a control area of ​​0.5 mu, a total of 2.5 mu.

[0044] The specific operation steps and methods are as follows:

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...
