Abstract:
The study was conducted to analyze species phenology and correlation between Aspect variations in different Aspect (East, West, North and Southern). The research exercise was carried out in Garhwal Himalayan Region of almost same altitudinal range. Eight randomly laid quadrates of 20 × 20 m were used to observe the reproductive Phenological events such as flowering initiation, open flower, fruit initiation and ripen fruit. In the study area dominated tree species was Lannea coromandelica, Adina cardifolia, Acacia catechu and Anogeissus latifolia are found almost all Aspect. Reproductive phenophases were monitored monthly for two season (winter and summer) and Statistical calculation Z-test, P-test, mean vector (μ) and length of mean vector (r) were carried out by using Oriana software, It may be concluded that the maximum flowering bud was found in Eastern aspect for Lannea coromandalica (7.8220) and the maximum number of open flower were found in Northern Aspect for Cassia fistula (8.8480). The maximum number of fruit initiation found in Eastern aspect for Anogeissus latifolia (20.9190) and the mature fruits were found maximum in Northern aspect for Adina cardifolia (71.1040).
