Lower temperature during the dark cycle affects disease development on Lygodium microphyllum (Old World climbing fern) by Bipolaris sacchari
Growth chamber experiments were conducted to examine environmental parameters affecting disease development by the indigenous pathogen Bipolaris sacchari isolate LJB-1L on the invasive weed Lygodium microphyllum (Old World climbing fern). An initial experiment examined three different temperature regimes (20/15, 25/20, 30/25 C; light/dark cycle) and three different periods of leaf wetness (12, ...
متن کاملExploratory surveys in Australia and Asia for natural enemies of Old World climbing fern, Lygodium microphyllum: Lygodiaceae
Lygodium microphyllum, Old World climbing fern, is native to the wet tropics and subtropics of the Old World and an invasive weed in southern Florida. Exploration for natural enemies of this weed was conducted between 1997 and 2002 in Australia, China, India, Indonesia, Japan, Malaysia, New Caledonia, Singapore, Taiwan, Thailand, and Vietnam. Two species of mites and 20 insect species were coll...
متن کاملNew sterol esters from the flowers of Punica granatum Linn.
Two new beta-sitosterol esters have been isolated from the flowers of Punica granatum Linn. (Punicaceae) along with the known compounds n-tricosane (3), n-heptacosanyl n-hexanoate (4), olean-5,12-dien-3beta-ol-28-oic acid (5), and olean-12-en-3beta-ol-28-oic acid (6). The structures of the new phytosterols have been elucidated as stigmast-5-en-3beta-ol-3beta-dodecanoate (beta-sitosterol laurate...
متن کامل2′-Methylpyrazolo[4′,3′:16,17]androst-5-en-3β-ol
In the title compound, C(21)H(30)N(2)O, there are five fused rings. The A and C rings adopt chair conformations, ring B adopts an 8β,9α-half-chair conformation and ring D adopts a 14α-envelope conformation. The pyrazole ring is planar. Inter-molecular O-H⋯N hydrogen bonds [H⋯N = 1.88 (5) Å] help to stabilize the crystal structure. The absolute structure was deduced from those of the starting ma...
متن کاملLup-20(29)-en-28-ol-3-one (betulone)
The asymmetric unit of the title compound, C30H48O2, contains two independent mol-ecules, the main difference between them being that the isopropenyl group is rotated by approximately 180°. In each mol-ecule, the fused six-membered rings have chair-chair-chair-chair conformations and the cyclo-pentane ring adopts an envelope conformation with the C atom bearing the hy-droxy-methyl group as the ...
