ABSTRACT.
We tested the effect of soil hypoxia from flooding on fruit drop in a mature orchard of ?Satsuma mandarin? (Citrus unshiu Marcow) trees on Pomeroy (Poncirus trifoliate (L.) Raf.) rootstock. Trees were flooded for 30 days with 10 cm water above the soil surface using a 60 cm high aluminum barrier which was buried to depth a 45 cm around the trees. Flooding began at flower anthesis and lasted until early fruit set. Flooding reduced the soil oxygen levels from 5 to 2 µg O2 cm-2 min-1. Relative fruit drop rate was higher in flooded trees than in non-flooded trees and the spring flush shoot numbers was reduced by flooding but not shoot length. Shoot water potential was reduced but leaf chlorophyll was not affected in leaves. Flooding immediately reduced net CO2 assimilation rate (ACO2), stomatal conductance and reduced quantum yield efficiency of the PSII after 3 weeks. There were only small
changes in internal CO2 concentration in leaves and no changes in maximum quantum efficiency (Fv/Fm) or basal chlorophyll florescence (Fo). This suggested that non-stomatal factors were more important than stomatal factors in limiting ACO2. Root function was reduced and an accumulation leaf starch was related to early fruit drop. Soil hypoxia from anthesis to early fruit set induced fruitlet abscission in Satsuma mandarin and was linked to tree water relations. |

Abstract:
Barley (Hordeum vulgare) is an important crop used for human consumption and mainly by the malt industry. Recently, a species of the root-knot nematode (Meloidogyne graminicola) was found and recorded to parasitize barley roots in Brazil. In this context, the objective of this work was to evaluate the susceptibility of 17 barley genotypes to M. graminicola in the greenhouse. Barley genotypes were individually inoculated with 5,000 eggs + second stage juveniles (J2) of Meloidogyne and kept in a greenhouse. After 60 days, the roots of each plant were evaluated for gall number, number of nematodes per root gram and reproduction factor (RF = final population / initial population). All barley genotypes evaluated behaved as susceptible to M. graminicola. The cultivar 'Scarlett' had the lowest RF (14.9), while the 'BRS Itanema' resulted in the highest RF (24.5).
