Embodiment 1

[0053] A kind of cultivation method of passion fruit stock of embodiment 1,

[0054] One, the cultivation of the hybrid progeny of rootstock fine-toothed green fruit adopts the conventional pollination method to carry out pollination, including the following steps:

[0055] (1) Selection and pretreatment of the female parent: On September 20, 2019, select 10 buds of healthy and disease-free Passiflora serrata that are about to open, use tweezers to open the petals and remove all their pollen, and use an impermeable Kraft paper bag to secure it and write the label;

[0056] (2) Selection and pretreatment of male parents: From 8:00 am to 10:00 am on September 21, 2019, select normal open,

[0057]For the flowers of healthy and disease-free green passionflower, use a clean brush to sweep its mature pollen into a clean disposable petri dish;

[0058] (3) Pollination: From 8:00 to 10:00 in the morning on September 21, 2019, use a clean brush to smear the pollen of Passiflora japo...

Embodiment 2

[0070] Embodiment 2 A kind of cultivation method of passion fruit seedling

[0071] One, the cultivation of rootstock green fruit fine-toothed hybrid progeny adopts the conventional pollination method to carry out pollination, including the following steps:

[0072] (1) Selection and pretreatment of the female parent: On October 8, 2019, select 15 buds of healthy and disease-free Passiflora japonica that are about to open, open the petals with tweezers and remove all their pollen, and use a water-tight Kraft paper bag to secure it and write the label;

[0073] (2) Selection and pretreatment of the male parent: at 8:00-10:00 am on October 9, 2019, select the flowers of Passiflora serrata that are normally open, healthy and disease-free, and use a clean brush to remove the mature pollen Sweep and drop into a clean disposable petri dish;

[0074] (3) Pollination: From 8:00 to 10:00 am on October 9, 2019, use a clean brush to smear the pollen of Passiflora japonica on the stigma...

Embodiment 3

[0086] Embodiment 3 rootstock resistance experiment comparison

[0087] The resistance of the rootstocks was compared by comparing the inoculation experiments of Passiflora serrata, the hybrid progenies of the green fruit and the hybrid progenies of the fine-toothed green fruit, and the control pictures of the stems of the experimental seedlings.

[0088] The inoculation method was used to verify the ability of the stem rot resistance of the hybrid progenies of the green fruit. Inoculate Fusarium solani (F.solani) on the PDA medium, place it in a constant temperature incubator at 28°C and incubate in the dark for 3-5 days, and when the colony is half full of the medium, use a sterile puncher The colony-growing culture medium was beaten into small cakes with a diameter of 60 mm. Select 20 strains of the fine-toothed green fruit hybrids whose seedling age is 4-6 months and have the same growth potential, draw a wound of 0.5 cm × 0.2 cm with a blade at the base of its stem, and ...

Abstract

The invention belongs to the field of high-quality seedling cultivation and application, and relates to a method for cultivating passion fruit seedlings. According to the method, a filial generation F1 obtained by hybridizing fine-tooth passion flowers and green-fruit passion flowers with high resistance is creatively selected as a stock, tender passion fruit branches with leaf buds are selected as scions, the seedlings cultivated through the grafting method are high in stem base rot resistance, and the branches of the seedlings are luxuriant, so that the seedling renewal planting frequency inthe passion fruit variety planting process is reduced, the cultivation management cost is reduced, the service life of passion fruit plants is prolonged, the harvesting life of the fruits is prolonged, the method has important significance in promoting large-scale planting of the passion fruits, operation is easy, cost is low, and the method is suitable for mass production in agriculture; and themethod has important enlightenment for high-quality seedling cultivation of other passiflora plants.

Description

technical field [0001] The technical invention belongs to the field of cultivation and application of high-quality seedlings, and in particular relates to a method for cultivating passion fruit seedlings. Background technique [0002] At present, the edible varieties of passionflower are mainly 6 types: purple fruit passionflower (Passiflora edulis Sims), yellow fruit passionflower (P.edulis Sim.F.flavicarpa Deg.), large fruit passionflower (P. .quadrangularisL.), banana passionflower (P.mollissima (Kunth) L.H.Bailey), camphor leaf passionflower (P.laurifolia L.), sweet fruit passionflower (P.ligularis Juss); The horticultural varieties of the species, the yellow fruit species, and the series of varieties that are crossed between the varieties are called passion fruit. Passion fruit is a tropical perennial herbaceous evergreen to woody climbing vine belonging to the Passiflora family Passiflora. Its origin is located in Australia and Brazil, and it is now widely planted in ...
