Definition of pharmacognosy 2). The size of the F 1 generation is a crucial matter, large F 1 population is difficult to handle, but the large F 1 population has the greater opportunity of rare recombination to occur. It can also be known as regeneration. (d) Cellular totipotency. Summary Sp hybridization occurs when a C has 2 attached groups sp hybrid orbital has 50% s and 50% p character the 2 sp hybrids are oriented at an angle of 180o to each other each sp hybrid orbital is involved in a σ bond formation and the remaining two p orbital forms two bonds a triple bond = one σ + two bonds A.K.Gupta, PGT Chemistry, KVS ZIET BBSR Chapter: Pharmacognosy and Phytochemistry : Cultivation, Collection and Processing of Herbal Drugs The crude drugs which reach the market and pharmaceutical industries will have passed through different stages that have some effect in the nature and amount of active constituents responsible for therapeutic activity. Types of Hybridization 3. Place the slide at room temperature for the hybridization of probe and DNA. Labelling and bagging. 5. HCCH Ethyne • Combine carbon AO first • Only combine (hybridise) AO we need • Each carbon attached to 2 groups so hybridise 2 AO • Remember conservation of orbitals Owing to the uniqueness of such properties and uses of an element, we are able to derive many practical applications of such elements. In a reversal of this process, a double-stranded DNA (or RNA, or DNA/RNA) molecule can be heated to break the base pairing and separate the two strands. Thermodynamics ppt lecture notes for lectures on our chemistry, study of the website and those topics in. Hybrid: The fusion of two cells of two different plants. These hormones are produced in almost all parts of the plant and are transmitted to various parts of the plant. iii) Transgenic plants and their applications . (a) Organogenesis. Manual of Practical Pharmacognosy &Phytochemistry Lab. This type of hybridization involves the mixing of one ‘s’ orbital and one ‘p’ orbital of equal energy to give a new hybrid orbital known as an sp hybridized orbital. sp hybridization is also called diagonal hybridization. Each sp hybridized orbital has an equal amount of s and p character, i.e., 50% s and p character. They also allow to achieve the large scale multiplication of disease-free plants, faster cloning and the conservation of desired genotypes, in a very short span of time. The WBCS Prelims syllabus consists of eight topics.
