Experiment Title Effect of fungicides on Pollen germination of Mango
Research Type Departmental Research
Experiment Background Mango (Mangifera indica. L.) is one of the most favorable and delicious fruit and is commonly 14 called “the king of fruits. It is one of the most important fruit crop of South Gujarat. It has greater economic impact. It is considered one of the most fragile crop to climate change and biotic stress. Various factors including diseases and insects are responsible for its low productivity. Among the mango cultivars, there is considerable variation in the quantity of production, fruit size, color, shape, flavor, texture, taste and susceptibility to diseases. Mango is attacked by several fungal diseases, i.e., blossom blight (anthracnose), dieback, fruit rot, root rot, malformation, and powdery mildew. Powdery mildew (Oidium mangiferae Berthet) is the most destructive disease affecting almost all the commercial cultivars causing considerable reduction of quantity and quality of mango yields. Mango powdery mildew is not easily controlled with cultural practices alone so mango orchards in South Gujarat are routinely sprayed during the bloom period by the use of several fungicidal applications. Effective control of powdery mildew is essential for a good fruit set. Besides the extensive use of fungicides for controlling mango powdery mildew, their effect on pollen germination and fruit yield must be studied. Good pollen viability and germination ability are necessary for mango fruit setting. A major goal of growers is obtaining the maximum yield. To achieve good yields, such growers must act with control measures during flowering with compounds that do not affect pollen vitality. Numerous studies have been done on the detrimental effects of fungicides on pollen germination, fruit set and yield, Dag et al., found that fungicides reduced pollen germination and fertility in mango. They inhibit pollen germination and pollen tube formation and thus affect fruit production. Hence, it is important to select fungicides that do not damage pollen vitality. So, considering the problem present experiment is furnished to know detrimental effect of fungicides on pollen vitality.
