FAQs

What is a typical example of cross-pollination? ›

The examples of the cross-pollinated plants are grasses, maple trees, tomato etc. In tomatoes the pollen grains are transmitted by the bees or the insects. Except tomato, all other plants given in the options are self-pollinated plants.

Wheat commonly is crossed by hand pollination or by approach crossing, so both methods are illustrated. Approach crossing can be used effectively to obtain crossed seed with a minimum of labor in both the field and greenhouse. Seed set from approach crossing is generally high.

Since the florets of rice are adichogamous, most of the florets are self‐pollinated at the time of floret opening (Jagoe, 1931).

Examples of cross-pollination plant

Apples, plums, pears, raspberries, blackberries, blackcurrants, strawberries, runner beans, pumpkins, daffodils, tulips, heather, lavender, and most blooming plants are examples of plants that employ insects for cross-pollination.

Cross-pollination is found in both angiosperms (flowering plants) and gymnosperms (cone-bearing plants) and facilitates cross-fertilization and outbreeding.

Tomatoes are self-pollinating plants; thus, emasculation (removal of the anthers from the female parent) is essential. All wild tomato species can be crossed with cultivated tomatoes (although it may be difficult); this is useful because wild tomatoes are a great source of desirable traits.

cross-pollinating. Readily crosses with any Beta vulgaris species: Swiss chard, leaf beet, spinach beet, etc. Will cross pollinated with parthenocarpic cucumber varieties. Please note: it is a commonly held belief that cucumbers will cross with squash and melons.

Various methods of cross pollination are entamophily (pollination by insects), anemophily (pollination by wind), hydrophily (pollination by water), zoophily (pollination by animals) and ornithophily(pollination by birds).

Cowpea is a self-pollinated crop and this is encouraged by the arrangement of floral parts. However, outcrossing has been reported and frequency of occurrence could vary depending on the genotypes involved and the environment where grown.

How are rice and wheat pollinated? ›

Their pollen grains are viable for only a few minutes. The period is sufficient for bud pollination to take place. Therefore despite being chasmogamous, rice and wheat are bud pollinated.

Cross-pollination is essential for apples, pears, most sweet cherries, and most Japanese plums. Cross-pollination is not essential, but does improve the number of fruit that form on apricots, European plums/prunes, tart cherries, peaches and nectarines. Pollen is primarily transferred by honeybees.

Examples. Examples of plants that use insects for cross-pollination include apples, plums, pears, raspberries, blackberries, blackcurrants, strawberries, runner beans, pumpkins, daffodils, tulips, heather, lavender, and most flowering plants.

Wheat is a strict self-pollinating crop, with less than 1% probability of cross-pollination (Griffin, 1987; Martin, 1990; Hucl, 1996), which is due to its cleistogamic (closed) floral morphologies (Nguyen et al., 2015). Wheat florets are hermaphrodites.

Tomatoes are self-pollinating, meaning they have flowers that contain both the male and female parts, so more than one plant is not needed for reproduction. The pollen falls within the flower to pollinate itself. That doesn't mean insects and wind aren't important, though.

In this process, the pollen grains transfer from the stigma of the same or genetically similar flower. Self-pollination can be observed in legumes such as orchids, sunflowers, peas, peanuts, oats, peaches, potatoes, wheat, and others.

The mixing of different characteristics occurs during seed development, and all flowering and cone-producing plants can cross-pollinate by natural or mechanical methods. This happens with plants in the same genus with some more vulnerable than others. It is rare for plants in different genera to cross-pollinate.

Eggplant is a self-pollinating plant, the flowers contain both anthers (which produce pollen) and pistils(which receive pollen). A light breeze or movement of flying insects can shift the anthers to the pistils in the flower and thus complete pollination.
