Effect Of Treatment

Background: Shallots are one of the horticultural commodities with low production growth value in Indonesia. Shallots production in Indonesia is limited by the quality of planting material and the climate, especially temperature. The flowering of shallots is a significant obstacle to the regulation of tuber development and bulbils. This study aimed to examine the effect of treatment on the initiation of flowering and the formation of bulbils. Methods: The method used was a complete randomized block design with six treatments: without treatment, vernalization at 5oC, Immersion GA3 100 ppm, Immersion IAA 100 ppm, Immersion NAA 100 ppm, injury to the flower stalk and three replications. Result: The treatment of flowering initiation and the formation of bulbils had a significant effect on the flowering day, the number of flower stalks, the percentage of flowering plants, number weight of bulbils and weight of bulbils. GA3 and vernalization can speed up the appearance of flowers and increase the percentage of flowering plants. GA3 and the opening of the flower stalks can encourage the formation of bulbils with a higher weight and diameter of the tubers. The flowering day had a negative correlation with the number of bulbils formed. Bulbils formation requires a higher content of endogenous GA3. GA3 can initiate the flowering and formation of shallot bulbils.

Effect Of Age

Background: Problems shallot cultivation in tropical regions such as Indonesia, is low productivity. Planting material is one of the causes of low productivity. The planting material used is a bulb that has been used continuously. It is makes planting material susceptible to infectious diseases and viruses. Efforts can be made to reducing the attack of virus infections in the planting material of the bulbs is by using seeds. However, seed production in Indonesia is still low due to the difficulty of flowering and low viability of seeds. The aim of this research was to detect flowering ability from the source of bulbs flowering and non-flowering clumps using Hd3a primers and endogenous GA3, also the effect of age of bulbs to flowering of shallot. Methods: The study used a complete randomized block design. The treatment consisted of two factors with three replications. The first factor was source of bulbs flowering and non-flowering clumps. The second factor was age bulbs which consists of three levels, namely the 60, 80 and 90 days age bulbs. The contents of gibberellins was analyzed using HPLC analysis. Molecular analysis to determine the potential of flowering genes used SSR primer (Hd3a). Result: Hd3a primer can be used as a marker of flowering shallot. Source of bulbs flowering and non-flowering clumps have the same flowering potential gene. The percentage of flowering in flowering clumps was higher than non-flowering clumps and correlates with endogenous gibberellins content. The age of bulbs indicates that older bulbs gave a higher percentage of flowering.

ABSTRACT: The production and quality of roses are influenced by fertilization management. The aim of this experiment was to evaluate the effects of doses of iron (Fe) in the production of potted rose bushes ( Rosa hybrida ). Treatments were based on five doses of Fe (0, 1, 3, 5 and 15mg kg-1) applied on the substrate, in a randomized block design with four replications. Seedlings presented two pairs of leaves and were individually transplanted into plastic pots (0.8dm3) containing commercial substrate. Each experimental plot consisted of a vase with a plant with two flower stalks. The following parameters were evaluated: number of leaves and flowers per flower stalk; dry matter production of roots, leaves and flowers; plant height and diameter and floral longevity. In addition, foliar levels of total chlorophyll and Fe were determined. Fertilization with Fe increases the production and quality of flowers of the rosebush cv. 'Shiny Terrazza' (r). Dose of Fe to be added to the substrate used in this study for maximum economic efficiency for this cultivar is 3.6mg kg-1.

Differences in levels of lignin in the plant between conventional and transgenic cultivars RR has been reported by several authors, however, there are few studies evaluating the influence of spraying of glyphosate on the lignin in the plant and RR soybean seeds. The aim of this study was to evaluate the physiological quality of RR transgenic soybean seeds and the lignin contents of plants sprayed with the herbicide glyphosate. The assays were conducted both in greenhouse and field in the municipality of Lavras, MG, in the agricultural year 2007/08. The experiment was arranged in a splitplot design with four replicates, considering the treatments hand weeding and herbicide glyphosate as plots, and five RR soybean cultivars (BRS 245 RR, BRS 247 RR, Valiosa RR, Silvânia RR and Baliza RR) as splitplots. In the greenhouse, the cultivars tested were BRS 245 RR and Valiosa RR in a randomized block design with four replicates. The sprayings were carried out at stages V3, V7 and early R5 (3L/ha). The 1000 seed weight, mechanical injury, germination and germination velocity index, emergence velocity index, accelerated aging, electrical conductivity and water soaking seed test, lignin content in the seed coat, in the stem and legumes were determined. The spraying of glyphosate herbicide, in greenhouse and field, did not alter the physiological quality of seeds and the lignin contents in the plant.

The Impact

Exposure of bulbs to cold, a physiological phenomenon called vernalization, and bulb size are important factors in the production of lily bulbs and flowers. This study aimed to verify the influence of vernalization of bulbs on flowering cut lily plants, as well as the impact of size and shape of harvest on the production and quality of flowers and bulbs. In turn, the way the stems of the plants used for cut-flower production are cropped is of higher importance for the production of new flower bulbs. In this sense, the experiment was conducted in Viçosa, MG, in a greenhouse in a randomized block design, in split splot scheme with three replications, in which the vernalization periods (25, 35 and 45 days at 4 ± 1 C) constituted the plots; bulb sizes (diameters of 3.2-3.8 cm; 2.5-3.2 cm 1.9- and 2.5 cm), subplots and ways to harvest (full harvest of the stem at the required length for the commercial harvest of the flower, commercial stem harvest at the commercial length, maintaining 10cm of stem in the soil; removal of the floral buds as soon as their appearance is observed and harvest at the end of the season), the sub subplots. The bulbs were planted in beds, with 15 x 20 cm spacing. It was evaluated the number of plants that flowered and the number of flowers, the length and the diameter of the floral buds, fresh and dry weights, diameter and plant height as well as number, perimeter and amount of fresh and dry bulbs. There was a decrease in the plant height with the increase of the vernalization period and a reduction of the diameter of the planted bulbs, as well as of the number and the fresh and dry weights of the produced buds. The production of flowers and buds in number, size and weight was directly proportional to the size of the planted bulbs, while the form of harvest with removal of flower buds increased the number, the perimeter and the fresh and dry weights of the buds. Bulbs with diameter between 3.2 - 3.8 cm, stored for 25 days in cold chamber enable greater production of flowers and the highest stem height, factors that favor the increase in market value.

ABSTRACT Sweet sorghum culture is an alternative to sugar and ethanol production. With the aim of evaluating herbicide tank-mix selectivity associated or not to sweet sorghum seed treatment with naphthalic anhydride, two experiments with ESX5200 and EJX7C5110 hybrids were performed in red oxisol (clayey) field conditions, in the municipality of Campo Mourão, Paraná state. A randomized block design was used, with 4 x 2 factorial scheme, with four replications. The first factor represented three herbicide associations and a control sample without herbicide, and the second factor was constituted by the absence or presence of seed treatment with naphthalic anhydride (5.0 g kg-1). Herbicide treatments were tank-mixes of atrazine + S-metolachor (2,640 + 480 g ha 1) (pre-emergence); atrazine + S-metolachlor + isoxaflutole (2,640 + 480 + 11.25 g ha-1) (pre-emergence) and atrazine + S-metolachlor (1,500 + 384 g ha-1) (post-emergence). The following characteristics were evaluated: intoxication, plant height, stalk diameter, number of internodes per stalk and plant density, performed 60 days after emergence (DAE); stalk yield and Brix, were evaluated on day 85 DAE. Atrazine + S-metolachlor tank-mix applied in pre or post-emergence did not affect growth, development, yield and stalk quality of the ESX5200 and EJX7C5110 sweet sorghum hybrids. Sweet sorghum seed treatment with naphthalic anhydride provided partial protection against the action of atrazine + s-metolachlor + isoxaflutole tank-mixes, being more evident for the ESX5200 hybrid.
