The profile and levels of bioactive amines in different sorghum lines were reported for the first time. The amines were quantified by ion-pair HPLC, post-column derivatisation with o-phthalaldehyde and fluorimetric detection. The extraction procedure was optimised: 420 lm particle size, extraction with 5% trichloroacetic acid and three extractions. The screening of 22 sorghum lines showed that four of the ten amines investigated were detected. Spermine and spermidine were the prevalent amines (100%), followed by putrescine (77%) and cadaverine (14%). Total amines ranged from 5.8 to 41.4 mg/100 g, and the polyamines represented 60?100% of the total. Sorghum without tannin had higher amines levels compared to sorghum with tannin and cadaverine was specific to samples without tannin. Hydric stress caused accumulation of spermidine in the grains and affected the levels of other amines at rates depending on the presence or not of tannin. Sorghum is a significant source of polyamines. |

Abstract: The present study proposes to evaluate extracts from shoots of healthy soybean and potato plants for the treatment of plants of the same species cultivated subsequently. Two experiments were thus conducted separately after the soybean and potato inoculum production phases. For soybean, the experiment was laid out in a randomized-block design with five treatments and four replications, in which the following treatments were tested: 1. absolute control without inoculum or pesticides; 2. farmer management with pesticides, without inoculum; 3. use of inoculum, without insecticides; 4. use of inoculum, without fungicides; and 5. use of inoculum, without pesticides. In the soybean crop, the tested inoculum improved plant development and, increased the potassium content of the plant tissue as well as yield. For the potato crop, a randomized-block statistical design was adopted with two treatments and ten replications, using varieties Ágata and Atlantic. The following treatments were tested: 1. absolute control without inoculum, with pesticides; and 2. use of inoculum (foliar spraying), with pesticides. With the use of inoculum, varieties Ágata and Atlantic showed distinct responses regarding disease incidence and yield. Late blight was the disease that most affected both varieties, but only Atlantic showed a reduction in its incidence when the inoculum was applied. Variety Atlantic also exhibited an increase in the most valued commercial calibers, besides an increase in yield, with the use of the tested inoculum. Cultivar Ágata showed a marked reduction in tuber defects with the use of the inoculum on the plants.
