S. Parmar University of Horticulture and Forestry, Nauni, Solan- 173230 (H. P.) during 2011- 2012. The study was carried out under three experiments, laid out in Randomized Block Design (factorial) with three replications. The experiment-I dealt with effect of auxin-chemical formulations and cutting types on rooting behaviour of Pittosporum floribundum in different seasons; experiment-II involved the study of air layering performance in Pittosporum floribundum using auxinchemical formulations while experiment-III related to nutrient analysis of leaves of Pittosporum floribundum to estimate the fodder values. Application of 0.4 % NAA + 3 % captan + 3 % sucrose-talc gave significantly maximum rooting (45.56 %) and enhanced root system (root number and root length) in spring season than in rainy season (32.22%). Coppice cuttings registered significantly superior rooting (42.22 %), mean root number (6.42) and mean root length (6.45cm) as compared to apical and basal cuttings in spring season. Overall significantly maximum sprouting of (100 %) was observed in cuttings taken from coppice shoots (C3) treated with 0.4 % NAA + 3 % captan + 3% sucrose-talc (T4) and planted during rainy season (S2). Significantly, maximum callusing (56.67 %) was registered when basal cuttings (C2) treated with 0.8 % NAA + 3 % captan + 3 % sucrose-talc (T6) in spring season (S1). Maximum rooting (60 %, mean root number (8.4) and mean root length (8.06cm) were achieved in spring season (S1) when coppice cuttings (C3) treated with 0.4 % NAA + 3 % captan + 3 % sucrose-talc (T4). Further, in air layering, significantly maximum callusing (36.67 %), rooting (63.33 %) and mean root length (13.53 cm) were registered in air layers treated with 0.8 % NAA + 3 % captan + 3 % sucrose-talc (T6) and prepared during rainy season (S2). Similarly, significantly maximum mean number of roots (4.68) were registered in air layers treated with 0.4 % NAA + 3 % captan + 3% sucrose-talc (T4) and prepared during rainy season (S2). Whereas the leaves of Pittosporum floribundum contains Crude protein (14.70%), Ether extract (3.81%), Crude fiber (10.28%), Organic matter (90.46%), Ash (9.54%), Neutral detergent fiber (30.67%), Acid detergent fiber (24.25%), Hemicellulose (6.42%), Lignin (7.33%), Calcium (2.80%) and Phosphorous (0.2 %).enThesis
