Problems solved by technology

Because when determining the flowering index, it is impossible to clearly determine which flowering branch
However, simply treat the clump type as a single plant type combined planting, and simply superimpose the measurement indicators, and it is impossible to screen out excellent varieties.

Embodiment 1

[0019] Selected 6 cluster-type spring dendrobium hybrid varieties with gradient differences in flower quality and broad representativeness: excellent varieties 'Senhe T-0' and 'Senhe T-2', medium varieties 'Huobird' and 'Senhe T-2' He 2004', inferior varieties 'Senhe H214' and 'Yinu 2#' were measured at the resting leaf stage of the annual seedlings of Dendrobium dendrobium and the full flowering stage of the corresponding three-year-old flowering plants respectively, and the obtained Data were analyzed using Excel and SPSS V18.0 software.

[0020] Seedling growth indicators include stem diameter, node length, number of nodes, number of leaves, leaf length, leaf width, plant height, fresh weight, root length, number of main roots, and root diameter. The measurement methods are:

[0021] Fresh weight (g): The weight of the whole plant without the stem nodes of the cuttings, weighed with an electronic balance, and the reading is accurate to 2 decimal places.

[0022] Plant heig...

Embodiment 2

[0054] When the annual seedlings of Dendrobium dendrobium enter the resting leaf stage, and the second leaf from the top to the bottom is about 5 cm long, 30 spring Dendrobium varieties 'Senhe 947' (evaluated as a middle-to-high variety in production) were randomly selected, and the leaves were measured. number, section number (method is the same as embodiment 1). The number of leaves is the total number of leaves of the plant, and the number of nodes is the total number of stem nodes from the root diameter to the top of the stem.

[0055] Take the mean value of the two indicators (the units are slices and nodes respectively), x 1 =3.9,x 2 =5.0, respectively substitute into the linear equation y 1 =2.061x 1 (number of leaves) -8.060, y 2 =1.534x 2 (Number of knots)-7.654, obtain its flower-forming quality comprehensive score y 1 =-0.022>-0.652 and y 2 =0.016>-0.652, which belongs to above-average variety, can be used for cultivation and production, and is consistent wit...

Abstract

The invention discloses an early screening method for good varieties of bundle plant type nobile-type dendrobium. The method comprises the following steps: a, determining the number of leaves and the number of segments of one-year-old seedlings in a leaf termination period; b, respectively substituting the mean values of the number of leaves and the number of segments into corresponding linear equations y1=2.061x1(the number of leaves)-8.060, and y2=1.534x2 (the number of segments)-7.654; calculating the comprehensive score of the quality of nobile-type dendrobium flowering; c, predicting the nobile-type dendrobium flowering quality according to the comprehensive score of the quality of nobile-type dendrobium products and a variety grade dividing reference standard. According to the early screening method for good varieties of the bundle plant type nobile-type dendrobium disclosed by the invention, the variety screening efficiency is improved; the screening cycle is shortened; the production cost is reduced.

Description

technical field [0001] The invention relates to a method for screening plant varieties, in particular to a method for early screening of cluster-type dendrobium species. Background technique [0002] Spring Dendrobium is favored by consumers all over the world because of its rich flower shapes and colors and long flowering period. It is a very popular high-end potted flower in countries such as today, Britain, and the United States. [0003] The plant type of spring dendrobium potted flowers can be divided into single plant type and cluster plant type. The former has obvious main branches with few branches, generally only the main branches bloom, and the number of flowering nodes is more, the plants are tall and strong; the latter main branches Not obvious, with many branches, the number of flowering branches ≥ 2, the number of total branches ≥ 4, the plant is relatively low, and the pseudobulbs are thin. [0004] As Dendrobium dendrobii is a perennial plant with a long veg...
