GROWTH AND QUALITY OF CHRYSANTHEMUM (DENDRANTHEMA GRANDIFLORA) GROWN IN WET SHEET CULTURE AND DEEP FLOW TECHNIQUE

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.

O experimento foi desenvolvido na propriedade de um produtor tradicional, no Distrito de Holambra II, município de Paranapanema-SP (23º 4’S e 49º 00’ W), em cultivos rotineiramente desenvolvidos pelo produtor. Os tratamentos foram definidos por 6 níveis de tensão de água no substrato: 2, 3, 4, 6, 10 e 30 kPa. Para cada tensão foi calculado a altura correspondente na coluna de mercúrio, as lâminas e o tempo de irrigação. Os resultados obtidos demonstraram que a cultivar Puritan obteve a maior porcentagem de vasos de alta qualidade comercial (A1) nos tratamentos irrigados com as tensões de 2, 6 e 10 kPa e a menor porcentagem com a tensão de 30 kPa. UNITERMOS: Dendranthema grandiflora, tensão de água no substrato, manejo de água. FARIAS, M.F., SAAD, J.C.C., VILLAS BÔAS, R.L.COMMERCIAL QUALITY OF POT CHRYSANTHEMUM, CULTIVAR PURITAN, IRRIGATED AT DIFFERENT SUBSTRATE WATER TENSION IN A GREENHOUSE 2 ABSTRACT The objective of this research was to identify the substrate water tension that could result in better commercial quality of chrysanthemum Puritan, pot cultivated and grown in greenhouse. The present work was developed in a commercial field of a traditional flower grower in Holambra II, Paranapanema-SP (23º 4’S and 49º 00’ W). The treatments were 6 levels of substrate water tension: 2, 3, 4, 6, 10 and 30 kPa. For each tension, the corresponding tensiometer mercury column height, water depth and irrigation time were defined. Results showed that the greatest high quality vase percentage (A1) was obtained in the treatments which were irrigated at 2, 6 and 10 kPa substrate water tension and the slowest one at 30 kPa.

Post Harvest

Chrysanthemum (Dendranthema grandiflora) is an ornamental plant that has high economic value, including flowers that are in great demand at domestic or abroad. As cut flowers, chrysanthemums are used for decoration and flower arrangements at weddings, and for opening new offices. The quality of cut flowers depends on the appearance and durability of freshness. Flowers with prime quality have a higher sale value compared to low-quality cut flowers. To maintain the quality of prime cut flowers still need to be implemented several treatments, especially when the flowers are ready to harvest to the consumers. The handling of post-harvest chrysanthemums is an important factor that is inseparable from the stages of cultivation and greatly influences the selling value and added value that will be obtained by farmers and traders. The use of pulsing and holding liquid during display will extend the chrysanthemum vase life. By implementing post-harvest chrysanthemums in accordance with handling procedures (SOP), chrysanthemums will be obtained that can meet quality standards and can provide added value for farmers and flower traders

This work evaluated the effect of aqueous plant extracts from chrysanthemum (Dendranthema grandiflora Tzvelev), cinnamon (Melia azedarach L.) and clove (Syzygium aromaticum L.) in the physiological and sanitary quality of germinating Chenopodium quinoa Willd (quinoa) seeds, as an alternative to seed treatment. The experiment was carried out under laboratory conditions in the year 2018. The experimental design was completely randomized in a 2×10 factorial scheme (two lots of quinoa seeds × ten doses of concentrated plant extracts), with four replicates each. The quinoa seeds were exposed to the plant extracts separately for ten minutes by submersion at the concentrations of 0, 1, 5 and 10%. The variables evaluated were germination, first germination count, field emergence, germination and emergence speed index, seedling length and sanity. The aqueous plant extracts of Dendranthema grandiflora Tzvelev, Melia azadarach L. and Syzygium aromaticum L. used in the quinoa seed treatment raised the emergence speed and the fungi control of these seeds within the variations and situations of each batch. The D. grandiflora extract, in all concentrations used, improved seed germination index, obtaining the highest rate of 70% in seeds treated with 5% concentration compared to the control treatment, which obtained 59%. M. azedarach (10% concentration) is the best treatment for emergence speed improvement, while S. aromaticum (10% concentration) provides the highest control of pathogens: 28% in relation to the control treatment that obtained 75%. These results highlighted the viability of the use of these species with low toxicity to man and the environment as treatment of quinoa seeds.
