Pollen Grain Observation Based on orthogonal experiment results, the power of the ultrasonic homogenizer was set to w and the sonication treatment lasted for 5 s each time with an interval of 10 s for a total of 7 times. Under blue exciting light, the green fluorescence was observed from both the treatment and control groups, and no visible difference presented.
Intercrop with pineapple, peas, gram, beans, papaya, turmeric, Ginger etc. Guava can in turn be used as an intercrop for other large trees such as Mango, Jackfruit, Coconut etc. To provide a strong framework and scaffold of branches. The system of training is open centre, in which the plants are headed back.
Primary shoots are retained for the initial framework which The feasibility of guava subsequently pruned one third to half after 3 months. After making the initial framework, the two side shoots are permitted to grow initially and after years, doubling of selected branches is continued.
As the flowers and fruits are borne on current season growth, thinning out is beneficial to encourage new shoots after harvest. All dead, diseased, unproductive branches, crowded shoots and water sprouts should be pruned back annually. Guava plants generally flower twice in a year viz: High yielding cultivars bear such heavy crops that many limbs are broken or badly bent.
Fruit thinning should be done in such a way that the tree will retain one fruit for every 50 leaves. Bagging at an early stage, found most effective against insect and disease infestation.
Protects the fruits from bird and bat damage. Getting fruits of good shape and size using brown paper bags. Pest and diseases of guava Fruit fly: The insect lays eggs at a time inside the fruit inserting ovipositor at maturity stage.
Eggs hatch within days and start feeding on fruit pulp. Fruit bagging is the most effective way to control the pest. Damaging the infested fruits with insect. Trap material should be changed at every days Fruit borer: The insect bores into the fruits at early stage and feed on the flesh and seeds.
Infestation of the pest is more frequent in the hilly regions. Mealy bug, scale insect and white fly: The insects suck on young shoots and leaves, secrete honey dew and create sooty mould.
Clean cultivation Infested leaves and shoots should be pruned and damaged at early stage of infestation. It can be controlled spraying Admire SL 0. Anthracnose caused by Colletotrichum gloesporioides is serious disease of guava.
The affected plants begin to die back from the top of the branch, while shoots, leaves and fruits are readily affected. The growing tips gradually turn dark brown and the black necrotic areas extend backward causing die back.
The disease is caused by Fusarium. It is characterized by the yellowing of leaves followed by drying of leaves and twigs from the tip and complete wilting of plants within days. It is difficult to control the disease by chemical means. Cultivation of resistant cultivars When the fruit ripens, the green colour changes to yellowish green or yellow.
Guava is harvested by hand with proper care.Updates Bertuzzi Plant on TV! Click here to see one of the latest Bertuzzi plant on the Vietnamese 3NTV channel..
