The feasibility of guava

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.

The feasibility of guava

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.

Complete Cultivation Guide of Guava Fruit

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.
