Abstract:
اجريت تجربة حقلية باستخدام اصص بلاستيكية في كلية التربية - جامعة تكريت بهدف دراسة تاثير حامض الهيوميك والاوكسينات في الصفات المظهرية والتشريحية لنبات حشيشة الليمون ومحتواه من المادة الفعالة, نفذت التجربة العاملية وفق التصميم العشوائي الكامل CRD وبثلاث مكر | Afield experiment was conducted using plastic pots on lemon grass to study effect of Humic acid and Auxins in growth, anatomical characteristics and its content of active constituents this plant in Tikrit University - College of Education, using the factorial experiment in CRD.The first factor was humic acid as organic acid fertilizer and two ways for applied, The first spraying with Lighumus 18 concentration 1.5 ml/2L of water(H1).The second addition Liqhumus 18 with irrigation water 1.5 ml/2L of water(H2)In addition to the treatment control(without Liqhumus 18(H0). The second factor two type of growth regulators(IAA And IBA) and their mixture as follow : 1 - spray growth regulator IAA 150mg/L(A1).2 - spray growth regulator IBA150mg/L(A2).3 - spray the mixture (IAA+IBA) 150mg/L(A3).4 - (Control) spraying with water. The data analysis ststistical using analysis of variance test (ANOVA) and compared between the treatment using Duncan test at 5% level of probability, and results of the experiment were as follow : 1 - The treatment (H2A3) was superior in plant hight(150.92cm), leaf area(3278.0cm2), number of leaves/plant(49.16)and shot dry weight(153.86 g) While the lowest value of plant high were(127.17cm)leaf area(1341.0cm2), leaf number/plant(29057)and shot dry weight (98.58gm)in the control treatment.2 - The treatment (H2A3) was superior significantly in all plant elements content : Nitrogen(2.78%), phosphorus(0.388%), potassium(2.95mg/l), Iron (87mg/i), Copper(16.8mg/l)and Zinc(15.8mg/l)whereas control treatments gave the lowest value were (1.31%), (0.29%), (1.05mg/l), (47.66mg/l), (12.0mg/l)and(3.10mg/l)respectively.3 - The treatment (H2A3)gave high number of oil cell in the leaf blade(5.88)cell, leaf mid rib(5.88)cell and leaf sheath(6.88)cell while less value were in the treatment(H0A2)which gave(3.22)cell in leaf blade and(2.66)and(3.66)cell on midrib and sheath respectively gave by control treatment4 - The treatment (H2A3) was superior significantly increased the volatile oil percentage by (1.04%), Specific gravity(0.9460), oil density(0.9260)and refractive index(1.4839).while less percentage were (0.68%), (0.8890), (0.8880)and(1.4820)respectively in the control.5 - The treatment(H0A3)was superior significantly in Citral a compound percentage by(32.87%), total citral(54.59%)and linalool(11.53) hn the leaf and sheath.in compare with treatments(H0A1), (H1A0)and(H1A2)which never contain Citral, while less percentage of total Citral was (2.06%)in the control.6 - The treatment(H0A1)was significantly increased compound Citral b compound percentage(27.82%) in the leaf and sheathwhile less Citral b percentage was(1.90%) in the control.7 - Superior the treatment(H2A0) significantly in Limonen compound percentage by(88.81%) in the leaf and sheathwhile less Limonen percentage was(21.72%) in the treatment(H1A1).8 - the treatment(H1A1)was significantly superior in Myrcin compound percentage by(35.83%) in the leaf and sheath in compare with(H1A0) which never contain Myrcin.9 - the treatment(H1A3)was significantly superior in Geraniol compound percentage by(36.14%) in the leaf and sheath in compare with(H0A3)and(H2A1) which never contain Geraniol.
