The invention belongs to the technical field of plant planting, and specifically discloses a prevention and control method for stem-base rot of passiflora caerulea. The prevention and control method for the stem-base rot of the passiflora caerulea comprises the following steps: (1) cutting a diseased part; (2) disinfecting a cut: after the cut is coated by alcohol, covering the cut by adopting a disposable cover bag; (3) performing coating by using a bactericide: coating the cut by adopting the bactericide, and covering the cut by adopting a disposable cover bag; (4) performing coating by using a recovery agent: coating the cut by adopting the recovery agent, and covering the cut by adopting a disposable cover bag; (5) performing painting by using a whitening agent; and (6) performing binding. The prevention and control method for the stem-base rot of the passiflora caerulea provided by the invention is scientific and effective, and breaks a current prevention and control method for spraying treatment only by using a single chemical agent; and chemical agent prevention and control and a physical matching technical measure are combined, the diseased part is treated in a targeted manner, and transmission and spread of the stem-base rot of the passiflora caerulea are timely and effectively stopped.

A method for group seedling cultivation of the apex of Passiflora violet, the method comprising anti-browning of explants, disinfection treatment, primary induction culture of axillary buds, induction culture of callus, subculture proliferation culture, rooting induction culture and bottle seedlings Transplanting technology link: take the young top shoots as explants, soak them in a mixed solution of antioxidant Vc and citric acid, and then sterilize them with potassium permanganate solution to improve the antioxidant and anti-browning effects of young explants. Ability and vitality; add activated charcoal and polyvinylpyrrolidone to the 3-stage medium of axillary bud induction, callus induction and subculture to absorb and secrete harmful substances and inhibit the production of browning substances. By adopting this method, the polluting rate and the browning rate of the initial induction of passionflower top shoots can be controlled below 10%; the initial induction survival rate of top shoots reaches more than 90%, the subculture multiplication coefficient of clustered buds is more than 5.0, and the rooting rate is more than 90%. ; The survival rate of transplanted bottle seedlings is over 95.0%. The invention can meet the needs of industrialized seedling cultivation.

The invention provides a passion flower reference gene PeNADP and a screening method and an application thereof, which belong to the field of molecular biology. The RNA-Seq sequencing data is used foranalyzing moderate or highly stable genes in the expression quantity to serve as candidate reference genes; according to the expression quantity value of the PeNADP, two genes with the highest expression quantity and two medium-high expression genes are selected, the primer is designed, verification is carried out on mRNA of different tissue parts of the passion flower variety with obvious phenotypic difference, the expression stability of each candidate reference gene is evaluated by utilizing software, and finally the proper passion flower reference gene PeNADP is screened out. The reference gene PeNADP can be stably expressed in stems, leaves, flowers and fruits of Tainung No.1 and gold berry No.2., and reference is provided for subsequent scientific research related to passion flowergene expression.

The invention discloses a seedling cultivation method capable of enhancing the resistance of a passion fruit plant to the stem base rot. The seedling cultivation method is characterized in that passiflora coccinea is taken as a rootstock, a passion fruit branch is taken as a scion, a splitting method is adopted for grafting cultivation, and a passion fruit seedling resistant to the stem base rot is obtained after grafting survival. The seedling cultivation method specifically comprises the following steps: rootstock selection and pretreatment, scion pretreatment, grafting, post-grafting management, transplantation and the like. The seedling cultivation method disclosed by the invention has the benefits that the advantages of the passiflora coccinea in the resistance to the stem base rot and the excellent fruit flavor of a passion fruit are integrated, and the defects that an original passion fruit seedling is susceptible to the stem base rot and is not strong in resistance are overcome, so that diseases in the passion fruit planting process are reduced, and the requirement that the seedling is required to be replanted every 1 to 3 years is avoided; the life span of the passion fruit plant and the fruit harvest life are prolonged, and the cultivating and planting costs of the seedling are reduced; therefore, the seedling cultivation method is of great significance in promoting the large-scale planting of passion fruits and has important enlightenment for the cultivation of high-quality seedlings of other plants of passiflora.

The invention relates to a homeopathic formulation prepared from the six homeopathic strains tabacum, Nux vomica, Aurum metallicum, Passiflora incarnata, Agnus castus and Lobelia inflata, said homeopathic formulation having beneficial effects on persons on tobacco or psychotrope withdrawal.
