The study was conducted to investigate the influence of Indole Acetic Acid (IAA), Indole Butyric Acid (IBA) and Naphthalene Acetic Acid (NAA) each at 0, 1000, 2000, 3000, 4000, 5000 or 6000 ppm on the semi-hardwood cuttings of guava (Psidium guajava L.) Cv. Sufida taken in April, 1996. The cuttings were dipped in these solutions for 5 minutes. After treatment, the cuttings were planted and covered with transparent plastic sheet to arrest the water vapours for maintaining humidity. The experiment was laid out in the lathe house of Horticulture Section, Agricultural Research Institute, Tarnab, Peshawar. The auxins had no effect on the number of days to bud sprout whereas, sprouting in itself was significantly increased by IBA at 1000 and 3000 ppm and NAA at 2000 ppm with 79.84, 75.96 and 76.59% respectively. The highest survival (12.50%) was noted in the cuttings treated with IAA at 3000 and 6000 ppm, IBA and NAA both at 6000 ppm. IAA at 3000 ppm significantly increased the number of leaves (16) per cutting. The highest number of roots (23.75) per cutting was recorded in the cuttings treated with IBA at 4000 ppm. The significantly maximum root length (4.13 cm) was noted in the cuttings treated with IAA 3000 ppm. Cuttings treated with IAA at 5000 ppm and IBA at 4000 ppm exhibited significantly highest root weights of 16.25 and 16.62 g respectively.
Olive (Olea europaea L.) cuttings taken from different varieties, were studied at the Agricultural Research Institute, Tarnab, Peshawar in February 2000.The cuttings were struck in 3000-ppm solution of IBA for 5 minutes before planting on beds prepared from sand, silt and FYM and then were covered with transparent plastic sheets for arresting proper humidity. Varieties Azarbaijan and Earleeg showed significantly maximum number of leaves per cutting (65.88 and 64.55 respectively) and shoot length (18.21 and 17.88 cm respectively). Variety Azarbaijan gave significantly higher sprouting percentage (48.66%) and the number of shoots per cutting (4.88) followed by variety Earleeg with 35.55% sprouting and 3088 number of leaves per cutting. The shoot diameters were not significantly different in either variety. It can be concluded from the results that variety Azarbaijan gave the best performance followed by Earleeg in the agro-climatic conditions of Peshawar as regards the cutting performance is concerned.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
