Abstract:
Prunella vulgaris is a perennial herb whose dry spike is used for medicine in China. It is also a very important traditional medicine. Current study was conducted to the biomass components factors of P. vulgaris in the different ecological environments for the development and protection. The results showed that the contribution factor of the production in different environments was significant differences. In favorable environment, the length of leaf, numbers of leaves, height, reproductive branch number of individuals gave the greatest contribution. In transitional habitats, the diameter of stem and spike, the length of leaf contributed the most. While in the undergrowth and dry hillside, the length of root, the width of leaf, the length of spike were the main factors for biomass.

02:27Trihybrid Crosses
Some of Mendel’s crosses examined three pairs of contrasting characteristics. Such a cross is called a trihybrid cross. A trihybrid cross is a combination of three individual monohybrid crosses. For example, plant height (tall vs. short), seed shape (round vs. wrinkled), and seed color (yellow vs. green).
The F1 generation plants of a trihybrid cross are heterozygous for all three traits and produce eight gametes. Upon self-fertilization, these gametes have an equal...
