Safflower (Carthamus tinctorius L.) presents a high susceptibility for the attack of pathogens, resulting in low productivity of seeds. Thus, we aimed to evaluate the physiological and sanitary quality of safflower seeds submitted to different treatments. The experiment was conducted in the Floricultural Sector and in the Didactic and Seed Research Laboratory, in completely randomized design, with 4x9 (lots of seeds and treatment of seeds), with four repetitions. The lots of seeds were cultivated in the crop 2017/2018, the sowing occurred in the first fortnight of each season of the year (autumn, winter, spring and summer). After collected, the lots were stored in cold chamber with average degree of humidity of 9.0%. The treatments of seeds were constituted by: control, thermotherapy via humid heat, thermotherapy via dry heat, Trichoderma harzianum, chemical fungicide with active ingredients of Carbendazim+Thiram, Metalaxyl-M+Fludioxonil and Carboxin+Thiram, vegetal extracts of Dendranthema grandiflora and of Melia azedaeach. We evaluated the seeds treated by the standard test of germination, length and mass of seedlings, emergence and sanity. We observed that all the tested treatments benefit the safflower culture, promoting improvement in its germination, with efficient establishment of seedlings in the field. At the same time that was carried out the infestation control of the pathogens on the same, among the treatments we highlight the chemical fungicide with active ingredient Carbendazim+Thiram.

The objectives of this work were to evaluate the method of thermotherapy via dry heat for the treatment of safflower (Carthamus tinctorius L.) seeds and, to verify its effect on the physiological and sanitary quality of seeds. The experiment was conducted in entirely randomized design, arranged in 5x6+1 factorial scheme, with six levels of temperature: 35, 45, 55, 65, 75 and 85 ºC and with five time periods: 24, 48, 72, 96 and 120 h, plus the additional treatment (control), with eight repetitions. The seeds were packaged in Kraft paper bags and submitted to the forced circulation greenhouse according to the factorial mentioned above. We evaluated the physiological and sanitary qualities by the standard tests of germination, length and mass of seedlings, emergence at field and sanity. We observed that the thermotherapy can be used as treatment of safflower seeds, and it is efficient in the control of phytopathogens, without damage to the physiological quality up to 45 ºC, and the combination of 45 ºC 24 h-1 provided better phytosanitary quality for these seeds, increasing their germinative potential and emergence at field.

Eggplant seeds germination can be slow and uneven, justifying the use of pre-germinative treatments to improve the performance of seed lots. One option of treatment is the controlled hydration of seeds by priming. In this way, this study aimed to evaluate the performance of eggplant seeds cv. Embu submitted to different methodologies of priming. The seeds used in the experiment were stored in cold chamber (15º C and 55% RH) in paper bags. The research was carried out at Central Laboratory of Seeds/UFLA. The seeds were submitted to the priming in aerated solutions varying the following factors: temperature (15º C and 25º C), time (24, 48 and 72 hours) and solution (water, PEG, KNO3 and PEG+KNO3). Seeds were washed in running water and dried at 30º C, until the return to the initial moisture content, around 10%. The variables analyzed were percentage of germination, percentage of emergence, speed index of emergence and electrical conductivity. The treatments were arranged in a completely randomized design, according to a factorial arrangement 2x3x4+1 (control - seeds without priming). The results showed that priming improves the vigour of eggplant seeds with no effect on viability; the priming in water or KNO3 is efficient to improve the seed vigour and priming in water or KNO3 may use temperature of 15º C or 25º C for 24, 48 or 72 hours.

The objective was to evaluate the physiological and sanitary quality of cockscomb seeds stored for different periods. The experiment was conducted in a completely randomized design, with a 2x5 factorial scheme (two species of cockscomb: Celosia argentea L. and Celosia cristata L., and five seed lots with different storage periods: 0, 4, 8, 12 and 16 years, from the date of harvest) with four replicates. After harvesting each batch of seeds, in their respective years, they were stored with an average moisture content of 11% and average germination of 98% in cold chamber in packages of Kraft paper (15 ºC and 40% RH). It was observed that the average vigor (first count of germination) of the seeds of the two species of cockscomb was 88%, and the average germination of normal seedlings was 89 and 96% for the C. argentea and C. cristata species, respectively, with mean germination of 2.9 days for all storage periods. The relative frequency demonstrated homogeneity in the germination of the two species of cockscomb maintaining germinative viability in all periods of storage. It is concluded that the physiological potential and sanitary quality of the seeds of the C. argentea and C. cristata were preserved for periods ranging from zero to sixteen years of storage.

ABSTRACT Ozonation has been proposed as an alternative for the post-harvest treatment of plant products. Therefore, the objective of this study was to evaluate the influence of the pH on the efficacy of ozonated water to control microorganisms and to determine the possible effects of ozone on the quality of stored strawberries. To evaluate the influence of pH on ozonated water in Portola variety strawberries, the strawberries were divided into six batches. Three batches were exposed to ozonated water and three batches were exposed to non-ozonized water with different pH levels and an immersion time of 5 min. The pH values used were 3.0, 6.5 and 8.7. After the ozonation, the fruits were stored in a cold chamber at 5 °C for 6 days, and analyses were performed every two days. A completely randomized design was adopted using a 6x4 factorial scheme with three replications. The aerobic mesophiles, molds and yeasts, total coliforms and Escherichia coli were quantified, and the presence of Salmonella spp. was assessed. For the quality evaluation, the mass loss, titratable acidity (TA), pH, soluble solids (SS), SS/TA ratio and color were analyzed. The pH of the water was verified to influenced the effectiveness of the ozonated water to control the aerobic mesophiles and molds and yeasts. The ozonated water can retard fresh mass losses and maintain the pH, soluble solids, titratable acidity, SS/TA ratio and color variables.

ABSTRACT Brazil is the world’s largest producer of sugarcane (Saccharum officinarum L.) and research aimed at propagation has promoted higher quality in production. The objective of this study was to investigate the effect of the variation of micrometeorological elements on the survival and quality of pre-sprouted sugarcane plantlets. The study was carried out in a protected environment (UFRPE). Plantlets of the cultivar RB92579 were obtained by the technique of production of pre-sprouted plantlets. The protected environments were divided into four modules covered with low-density polyethylene plastic + photo-selective shade nets and one module without shade net. Micrometeorological data of global and photosynthetically active solar radiation, air temperature, substrate temperature, relative humidity and the solar radiation spectrum were recorded in each module. The experiment was conducted in a completely randomized design and the principal component analysis was used to verify the association between the cultivation modules, micrometeorological variables and crop variables. Anti-UV low-density polyethylene plastic + freshnet led to lower transmittance of global solar radiation, higher percentage of photosynthetically active radiation and lower plantlet mortality. Substrate temperature above 30.2 °C resulted in higher plantlet mortality. Larger spectrum in the red range led to the production of better quality plantlet. The use of freshnet shade net promoted adequate conditions for the cultivation of sugarcane plantlets and allows obtaining better quality plantlets.
