AI Technical Summary

Problems solved by technology

The premise of grafting and raising seedlings is the breeding of seedlings (rootstock), but the conventional method of accelerating germination and raising seedlings in sand beds often occurs that the seeds take root and sprout slowly (60-90 days), the germination rate is low (about 60%), and the root system is underdeveloped, causing transplanting. Problems such as low survival rate are not conducive to the development of subsequent grafting and breeding of lucuma
[0005] There are differences in the rooting and germination time, germination rate, and transplanting survival rate of different varieties of lucuma seeds. Literature (Xu Jian, Lu Yanchun, Wei Chizhang, Zhou Jing. Experiments on seed germination rate and grafting survival rate of different lucuma varieties (lines) [J]. South China Fruit Trees, 2014,43(01):55-56.) It is mentioned that there are differences in the germination rate and seedling rate of different varieties of seeds, the average germination rate is 82.8%, and the average seedling rate of germinated seeds is 78.5% , the germination rate and seedling rate of Xiantao 2 and Xiantao 1 are higher, but compared with Xiantao 2 and Xiantao 1, the germination rate and seedling rate of Xiantao 1 are lower than that of Xiantao 2

Embodiment 1

[0029] The screening of embodiment 1 exogenous hormone

[0030] The method for fast rooting and sprouting of lucuma seeds based on exogenous hormone treatment comprises the following steps:

[0031] (1) Seed selection: choose Xiantao No. 1 seeds with full grains, mature and healthy;

[0032] (2) Disinfection treatment: put the seeds into 2% sodium hypochlorite solution by volume fraction, soak and disinfect for 20 minutes, then clean them with warm water and dry them;

[0033] (3) Hormone soaking contrast experiment: put the sterilized seeds into different exogenous hormone solutions and clear water for 24 hours, and then take them out; that is, set up the following 4 groups of experiments: exogenous hormone combination GA 3 +BR, single hormone GA 3 , single hormone BR and clear water control group, each group treated 30 lucuma seeds, repeated 3 times:

[0034] ① Exogenous hormone combination GA 3 +BR:GA 3 (100mg / L): BR (0.05mg / L) = 1:1;

[0035] ②Single hormone GA 3 : ...

Embodiment 2

[0041] The screening of embodiment 2 hormone concentration

[0042] Step (1), (2) and (4) in embodiment 2 are identical with embodiment 1, and the difference of embodiment 2 and embodiment 1 is:

[0043] A, exogenous hormone solution selects hormone GA for use in the step (3) 3 Seed soaking in 3 concentrations, namely: 60mg / L, 80mg / L and 100mg / L. 30 lucuma seeds were soaked in these three concentrations respectively, soaked for 24 hours, and repeated 3 times. Observe the rooting and germination effect of seeds treated with different concentrations. See the comparative situation of seed rooting and germination effect figure 2 .

[0044] B, in the step (3), exogenous hormone solution selects 3 kinds of concentrations of hormone BR to soak seeds, is respectively: 0.05mg / L, 0.10mg / L and 0.15mg / L. 30 lucuma seeds were soaked in these three concentrations respectively, soaked for 24 hours, and repeated 3 times. Observe the rooting and germination effect of seeds treated with ...

Embodiment 3

[0048] The screening of embodiment 3 optimum soaking time

[0049] Step (1), (2) and (4) in embodiment 3 are identical with embodiment 1, and the difference of embodiment 3 and embodiment 1 is:

[0050] Use of exogenous hormones in combination with GA in step (3) 3 +BR:GA 3 (100mg / L): BR(0.05mg / L) = 1:1 to soak the seeds, set 3 different soaking times, 12h, 24h, 36h respectively, treat 30 lucuma seeds in each group, repeat 3 times. Observe the rooting and germination effects of seeds treated with different soaking times. The results showed that the seeds soaked for 24 hours had the best rooting and germination effect.

Abstract

The invention discloses a method for rapid rooting and budding of lucuma nervosa seeds based on exogenous hormone treatment, and belongs to the technical field of agricultural planting. The method comprises the processes of seed selection, disinfection treatment, hormone seed soaking and culture management, a hormone combined solution is used for treatment in the hormone seed soaking process, treated lucuma nervosa seedlings grow normally and have vigorous vitality and developed root systems, the rooting rate of lucuma nervosa seeds reaches 100% within 15 days, the budding rate reaches 100% within 30 days, and the germination rate reaches 100% within 30 days. Moreover, the germination uniformity of the seeds is high, the radicle length is long, the radicle thickness is large, the germ length is long, and the seedling raising period is obviously shortened, so that the seedling raising process is accelerated, the cultivated lucuma nervosa seedlings can greatly meet the requirements of grafting seedling raising, and the development of lucuma nervosa industrialization in China can be promoted.

Description

technical field [0001] The invention belongs to the technical field of agricultural planting, and in particular relates to a method for rapid rooting and sprouting of lucuma seeds based on exogenous hormone treatment. Background technique [0002] Lucuma nervosa (Lucuma nervosa A.DC.), also known as fairy peach, lion head fruit, egg fruit, peach olive, etc., belongs to Sapotaceae, and lucuma is a perennial evergreen small tree plant. It is native to the tropical regions of America. In recent years, it has been planted in Hainan, Guangdong, Guangxi, Yunnan, Fujian and other tropical regions in China. Large-scale planting has been formed in some areas. It has the characteristics of strong adaptability, less pests and diseases, and beautiful fruit shape. Lucuma fruit contains 29.1-30.6% of plant polysaccharides, 8.2-18.8% of starch, 1.0-1.42% of crude protein, 51.8-69.2 mg of vitamin C per 100 grams of pulp, and rich phosphorus, iron, calcium, and carotenoids and 12 kinds of a...
