In comparison to controls reared in isolation, female rats reared in the presence of an adult male from weaning attained puberty 5 days earlier when living in groups or almost 9 days earlier when living singly with a male. Accelerated sexual development occurred in the absence of accelerated physical growth.

Due to its indeterminate growth habit, maturation of cotton (Gossypium hirsutum L.) is affected by many environmental and cultural factors. An easy and reliable measure of its progression toward maturity that can be attained during crop development is needed for both production and research programs. As a cotton plant develops, first-position flowers progress toward the plant apex, and their re...

The high postharvest losses (40 – 50%) reported in the mango value chain are partly attributed to lack of reliable maturity indices. Harvest is dictated by intended use and target market for fruits. aim this study was establish indices three commercial varieties namely ‘Van dyke,’ ‘Kent’ ‘Tommy Atkins’ Embu County Kenya. At least eighteen trees (six per variety) were randomly tagged at 50% flow...

Nyctanthes arbor-tristis Linn is an ornamental and medicinal plant utilised traditionally in India. The seeds of N. were reported to contain immense pharmaceutical value due the presence essential oils iridoid glycosides hence it know its right stage maturity. morphological analysis fruit seed was done assess different stages At maturity, average length breadth 21.3±0.45 mm 16.7±0.13 respective...

Fifty-one ewes, 50 wethers and 51 rams of Finn x whiteface or Suffolk x whiteface breeding were slaughtered at an average age of 271, 361, 459, 557 or 652 d to study changes in maturity characteristics with changes in age. When metacarpal epiphyseal cartilage (growth plates) ossifies with age, break joints on the distal end of the metacarpals fuse and the end of the bone then appears as a spool...

objective: flowering time (ft) in cereals controlled by genes that had a main factor on plant development. methods: genetic and phenotypic diversity of four flowering time genes (ft2, ft3, ft4, ppd-h1) in 19 genotypes of cultivated and wild barley was evaluated and a total of 107 alleles were amplified. genotypes based on days to flowering time and molecular data were grouped into early, middle...

The reproductive biology and the gonadal development cycle of the Neotropical cichlid fish, Crenicichla menezesi, is described. This species exhibits sexual dimorphism only during the spawning season. First sexual maturity of females is attained earlier than the males. Both macroscopic and histological investigations of ovaries and testes revealed four stages of gonadal maturation. Mean batch f...
