Abstract: AVES, JUSTINE JOY MEDINA, MOJICA, MARINETTE PANGANIBAN and NUESTRO, LEI ANNE BAYBAY. Effects of Vesicular Arbuscular Mycorrhizal Root Inoculant on the Growth of Jatropha (Jatropha curcas L,) Cuttings. Research III. Cavite State University-Science High school, Indang, Cavite. April 2008. Adviser: Dr. Yolanda A. Tagan. This research study, Effects of Vesicular Arbuscular Mycorrhizal Root Inoculant on Indang, Cavite from September 2007 to December 2007 primarily to determine the effects of VAM inoculant on the growth of Jatropha cuttings. Specifically, it aimed to determine how VAM colonization enhanced the survival of Jatropha cuttings, to compare the effects of VAM and different rooting hormones on the survival of Jatropha cuttings and to assess the degree of VAM colonization on the roots of Jatropha cuttings. A total of 120 cuttings were arranged in a Complete Randomized Design (CRD) with four treatments replicated three times. Treatments evaluated were as follows: T1 — cuttings without VAM; T2 — cuttings treated with VAM; T3 — cuttings treated with VAM + Cocogro; and T4 — cuttings treated with VAM + NAA. Stem cuttings were subjected to observation for three months. The data gathered include percent survival of the cuttings, number of days of first leaf emergence, number of leaves, leaf length, primary root length and degree of VAM colonization. VAM inoculated cuttings had higher percent survival and mean number of leaves than cuttings treated with VAM + hormones; however, when compared to cuttings treated without VAM the result showed that water alone is better. VAM inoculated cuttings had the longest primary root length among the four treatments. VAM inoculated cuttings had the highest mean number of days of leaf emergence while cuttings treated with water alone emerged the earliest. Cuttings treated with water alone had the highest mean leaf length while VAM inoculated cuttings had the lowest mean leaf length. This study showed that VAM can colonize roots of Jatropha cuttings as manifested by the fungal spores shown in the microscopic examination. The spores were observed to have greenish substance around it.
