Question

Dehiscence is porous and basal in the anthers of:
a. Solanum
b. Cassia
c. Barberry
d. Maize

Answer 1

Hint: Dehiscence is the splitting, at maturity along a built-in line of weakness in a plant structure in order to release its contents, and is common among fruits, anthers and sporangia.

Complete Answer:
a. Dehiscence of the reproductive structure will be of following types:
1. Longitudinal: The reproductive structure lobes burst on the ventral suture, seen unremarkably in several flowers.
2. Transverse: it's seen in monothecous anthers, as in family Malvaceae.
3. Porous and Apical: organic phenomenon through the top pore, as seen in the potato family.

b. The flowers of Cassia didymobotrya and C auriculata have 3 styles of fertile anthers that dissent in orientation, size, shape, and spore production. Flowers with fight-handed or left handed vogue deflections, i.e., enantiostyly flowers, occur within the same flower cluster. In Israel, each species square measure pollinated by spore grouping droning females of arthropod genus pubescens.

c. Japanese barberry shrubs are hotter and additional wet than alternative plants, making associate atmosphere wherever ticks will thrive and reproduce, increasing the danger of transmission of Lyme and alternative probably dangerous infectious diseases, specialists say.

d. By the utilization of DH-producing techniques varied cistron mixtures are often fastened in homozygous kind in an exceedingly short time. Moreover, DH lines possessing high fertility and favourable agronomical characters are often utilised directly in heterosis breeding to supply new hybrids that satisfy market demands. reproductive structure culture may well be a great tool for making maize inbred lines.

Hence option ‘A’ : is the correct answer.

Note: Anther dehiscence is the final function of the anther that causes the release of pollen grains.
