yield in most crops is resulted from a number of physiological processes which occurred during plant growth and development. these processes are realized at morphological, pheonological and physiological levels and often are controllded by many genes. in order to determine the effective of physiological traits onseed yield of soybean (glycine max l.) cultivars and their relationship with yield ...

Environmental stress can alter genetic variation and covariation underlying functional traits, and thus affect adaptive evolution in response to natural selection. However, the genetic basis of functional traits is rarely examined in contrasting resource environments, and consequently, there is no consensus regarding whether environmental stress constrains or facilitates adaptive evolution. We ...

A sample set of 21 rice varieties composed of 20 BRRI developed modern rice varieties and one local variety was selected to detect the genetic variation by using 13 morphological traits, 14 physiological traits and 34 SSR markers. All these three methods divide the varieties into five clusters and showed that there exist high genetic variations among the genotypes. Cluster analysis showed that ...

In order to study on different methods of application of polyamines (putrescine, spermine, spermidine) on some morphological, physiological, enzymatic and vase life of Rosa hybrida cv. ‘Dolce Vita’, experiment was conducted as a factorial experiment in a completely randomized design with 32 treatments, 3 replicates and each replication containing 5 vases, a total of 480 vases were executed.
