Flowering characters studied

Ebook "The families and genera of vascular plants - Volume XIII: Flowering plants, monocots (Poaceae)" is the outcome of a modern phylogenetic analysis of the grass family based on multiple sources of data, in particular molecular systematic studies resulting from a concerted effort by researchers worldwide, including the author. In the classification given here grasses are subdivided into 12 subfamilies with 29 tribes and over 700 genera. The keys and descriptions for the taxa above the rank of genus are hierarchical, i.e.

In the present study, microalgal biomass (Anabeana circinalis and Scenedesmus quadricauda) was used as biofertilizer in cucumber cultivation. The response of cucumber growth characters to microalgal biofertilizer was evaluated. Moreover, rhizosphere microbial diversity and community composition of cucumber was analyzed through 16S rRNA high-throughput Illumina sequencing data. The results showed that microalgal biomass as biofertilizer significantly promoted height, number of leaves and flower buds, and stem diameter of cucumber. The application of a high concentration of S.

Thirty seven rice genotypes were evaluated for their variability with regards to yield and yield components. Estimates of heritability and genetic advance in percent of mean were also obtained for the above traits. All the characters under study except days to fifty percent flowering exhibited high heritability coupled with high genetic advance as per cent of mean, which indicated that these traits were controlled by additive type of gene action in the inheritance of these characters.

Line × Tester analysis was carried out using 13 lines and 3 testers to estimate heterosis on seed yield and its contributing characters in Opium Poppy. The 39 resulting hybrids along with their parents were evaluated in Randomized Block Design during Rabi 2019-2020. The analysis of variance revealed the presence of variability among parents and crosses for the characters studied.
