Anti-mitotic agents such as colchicine have been used to induce polyploidy in various plants. On the other hand, vincristine and vinblastine are also antimitotic agent extracted from Periwincle (Catharanthus roseus [L] G. Don) were previously studied to produce autotetraploid on shallot tuber (Allium cepa L.). Therefore, in this study phenotype character and ploidy of muskmelon (Cucumis melo L.) produced by etanolic extract of periwikle leaves were determined. The effects of different concentration of etanolic extract of periwinkle leaves on polyploidy induction in muskmelon were examined. Melon seedling of two days old were immersed in 0.5%, 0.1%, and 0.05% for 8 hours. Then seedling was grown on the polybag and a drop of each concentration of periwinkle leaves’s etanolic extract was added into apical shoot.  Melon seedling of ten days old were moved and cultivated and harvested on 60 days after cultivation. Phenotypic character such as: plant high, stem diameter, leaf area, fruit weight, fruit area around, flesh fruit thickness, skin fruit thickness, fruit horizontal diameter, fruit, vertical diameter, number of seeds, weight of 100 gram of seed, seed leght, seed width, and seed thickness were examined. The ploidy degree was determined by count of chromosome number root tips of second generation muskmelon sprout. Result of this study revealed that 0.05% etanolic extract of periwinkle leaves for 8 hours immersed is optimum concentration to induce autotetraploid muskmelon (4n=48). Autotetraploid phenotypic character of muskmelon produced by 0.05% etanolic extract of periwinkle leaves were generally bigger than control plants statistically significant in stem diameter, leaf area, and fruit horizontal diameter. The result also showed that the chromosome number of second generation autotetraploid muskmelon sprout was tetraploid (4n=48).

The study aimed to determine the effect of NPK Mutiara fertilizer and liquid Nasa organic fertilizer as well as each of the main factors on the growth and yield of melon plants (Cucumis melo L). The experimental design used was factorial 4 x 4 in Completely Randomized Design (CRD). The first factor was the administration of NPK Mutiara fertilizer consisting of 4 levels, namely: 0, 5, 10, and 15 grams/plant, and the second factor Nasa liquid organic fertilizer consisted of 4 levels, namely: 0, 3, 6, and 9 cc/plant. so that 16 combinations of treatments were obtained. Each combination of treatments consisted of 3 replications so that 48 units of the plot were obtained. Data from the observations were analyzed statistically (variance analysis) and BNJ advanced tests at the level of 5%. The parameters observed were flowering age, harvest age, stem diameter, fruit weight per fruit, the thickness of fruit flesh, and taste test. Research shows that the interaction of NPK Mutiara fertilizer and Nasa liquid organic fertilizer does not significantly affect all parameters, but singly NPK Mutiara fertilizer and liquid Nasa organic fertilizer give an influence on the parameters of observation. The main influence of NPK Mutiara fertilizer influences all observation parameters, namely flowering age, harvest age, stem diameter, widest leaf area, fruit circumference, fruit weight per fruit, production per plot, and thickness of fruit flesh. The best treatment is the administration of Pearl 5K NPK/plant (K1). While the main factors for the provision of liquid organic fertilizer Nasa affect the parameters of flowering age, harvest age, and widest leaf area. The best treatment is the administration of 6 ml/l water (N2) liquid organic fertilizer.

GROWTH AND PRODUCTION OF MELON CULTIVATED IN GREENHOUSE UNDER DRIP IRRIGATION   2 ABSTRACT The objective of this study was to evaluate the effect of different irrigation depths on melon growing in greenhouse. The experiment was conducted in an experimental area of the Engineering Departament of the Universidade Federal de Lavras, Lavras/MG. Melon (Cucumis melo L., var. Inodorus, cv. Vereda) was drip irrigated, in a two-day interval, with four different depths. Crop evapotranspiration (ETc) was calculated with a reduced class A pan evaporimeter (ECA). Irrigation depths were input using four different fractions of the net depth (LL): 0.5.LL, 0.75 LL, 1.0.LL and 1.25.LL. Each irrigation treatment was applied to three plants rows, each one containing 8 plants. Only 6 plants located at the central row of each treatment were used for measurement. Evaluated parameters were: plant height, stem diameter measures, average weight and fruit longidutinal and transversal diameters. Average weight and fruit longidutinal and transversal diameters were not significantly affected by irrigation depth; however, they  presented smaller size  than the one demanded by the market. Plant height average and stem diameter average measurements showed tendency to be higher on the irrigation depth equivalent to 0.75.LL. KEYWORDS: irrigation depth, Cucumis melo L., fruit weigth.

This experiment quantified the effects of three root rot pathogens on muskmelon (Cucumis melo L., var. cantalupensis) growth traits using computerized image analysis. Plants were grown from seed in sand infested with the soilborne pathogen Monosporascus cannonballus, Acremonium cucurbitacearum, or Rhizopycnis vagum. After 28 days in the growth chamber, images of plants were analyzed to quantify their response. Compared to noninoculated muskmelons, inoculated plants had significantly increased mean root diameter (45%), decreased root length (26%, primarily in roots of <0.5 mm diameter), decreased number of root tips (27%), decreased rhizosphere volume (40%), and decreased cumulative and mean surface area of leaves (24%). Effects of M. cannonballus on muskmelon growth were significantly different compared to A. cucurbitacearum and R. vagum. Isolate effects manifested a greater magnitude of difference on muskmelon traits than those observed at the species level. Multivariate analyses of plant responses were more powerful than univariate analyses to differentiate among effects of pathogen species and pathogen isolates. Discriminant analysis were useful to identify groups of plant traits modified by each fungal species or isolate at low disease levels. Digital image analyses proved to be a useful technique in quantitative assessment of plant damage caused by soilborne root rot pathogens.
