Abstract
To investigate the influence of various levels of SOP and dipping time on seed germination and growth of pecan nuts, a study was carried out at Horticulture Department, Agriculture University Peshawar, Pakistan (during 2012). The experiment consists of SOP levels (0,2,4,6,8 & 10%) and dipping times (5,10,15 & 20 hours) respectively in order to find out the optimum level of SOP and best dipping time for successful germination and better growth of pecan nuts. The results revealed that SOP levels and dipping time significantly affected most of the parameters under study. The interactions between SOP and dipping time showed significant differences for all parameters except germination percentage, root length, leaf area plant-1, stem diameter. The pecan nuts treated with 10% SOP solution showed best result regarding, number of roots plant-1(73.00), seedling height plant-1 (22.53 cm), stem diameter plant-1 (0.63 cm), root length (61.67 cm), germination percentage (70.83%). The mean data for dipping time indicated that the pecan nuts dipped for 10 hours showed best results for number of roots plant-1(69.00), seedling height plant-1 (19.04 cm), root length plant-1 (56.11 cm), germination percentage (65.00 %), and. It was concluded from the experiment that SOP @ 10% with 10 hours of dipping time gave best results in seed germination, seedling growth and establishment of pecan nuts plants under agro climatic conditions of Peshawar, Pakistan.

Summary
Mississippi, New Mexico, Georgia, Texas, known as Caryaillinoinensis, belongs to Albana, Louisiana, Oklahoma, Florida, North family Juglandaceae. Parameters To study the influence of SOP and dipping time on germination of pecan nut, the following growth parameters were studied. Germination percentage Germinated seedlings were counted and average was calculated by using the following equation. Statistical computer software, MSTATC (Michigan State University, USA), was applied for computing both the ANOVA and LSD [5] Results and discussion Germination percentage The mean data regarding germination percentage is presented in Table 1 .The analysis of variance revealed that the germination percentage was significantly affected by different SOP levels and dipping time, while the interaction of SOP and dipping time showed non-significant effect on germination percentage. The mean table 1 shows that the highest germination percentage (70.83%) was recorded in nuts treated with 10% SOP solution, closely followed by nuts treated with 8% SOP (67.50%) which was at par with each other. Dipping duration for pecan nuts shows a significant difference for germination percentage. Tomato seeds were primed with 2% KNO3 solution [6]
