Another process employed to increase the formation of volatile compounds in fmit is that of bioregulators. When a bioregulator is appHed to lemon trees an increase in both the aldehyde and alcohol fractions of the lemon oil extracted from the fmit of the treated lemon trees was observed (78). 

When Norbert was born, New Orleans was still a small town by modern standards.

Table 2 represents a summary of the design of the chlorpyrifos re-entry studies. Five sites (three in California, one in Arizona, and one in Florida) were selected. The California orange harvesting and lemon tree pruning represented high crop re-entry activities, while the Florida tomato and... 

Arizona cauliflower scouting represented low crop activities. Five orange harvesters and five lemon tree pruners were tested using concurrent dosimetry and urinary monitoring techniques. The re-entry intervals were 43, 2, and 1 days for the orange harvesters, lemon tree pruners, and scouts, respectively. Re-entry workers were monitored for 5- to 6-hr work days in California and for a 4-hr work day in Florida and Arizona.

As opposed to the case of B, very few works investigate the direct effect of Ca on phenolic metabolism. Castaneda and Perez [131], working with lemon trees, observed that the application of 10 pM of CaCh increased PAL activity one hour earlier than control only if the trees were treated with cell walls isolated from the fungus Alternaria alternater, or...

FIGURE 7.15 The leaf of a lemon tree afflicted with chlorotic stippling because of exposure to oxidants in a smoggy atmosphere. This condition, which can seriously damage vegetation, is characterized by bleached or yellow spots on the leaves. 

Synephrine [l-p-hydroxy-a-(methylaminomethyl)benzyl alcohol] (51) and its lower homolog, octopamine (52) have been isolated from the leaves of lemon trees (Citrus spp.) though previously they had only been found in animals (52). Further examination of the grapefruit led to the isolation of a base, feruloylputreseine (53), which is the structure assigned to subaphylline first isolated from the unrelated SaUola subaphylla C. A. Mey. (54).
