Abstract

There are many genetic which effect this fenotipic character, such as hybrid. In increasing of mulberry hybrids, it is needed to identify the characteristic of those hybrids. The purpose of this research is to identify morphological characteristics among mulberry hybrids. Observation was done to nine hybrids and five female, four male of mulberry. There are some similarities of morphological  characterictics i.e. : performance shcrub, pennivervis leaf, texture of leaf bottom smooth, phyllotaxis 2/5, leaf type singular, stem type woody, stem size cylinder, growth erectus, branch type monopodial, growth of branch patens, root type radix primaria, shoot position axillaris and it has stypulla. Differences of the characteristic on mulberry can be seen at leaf type shape, leaf bottom shape, leaf side, texture of leaf surface, leaf color, leaf index length/width, average of petiole length, lentisel density on surface stem, stem color, stem diameter, and average of internodal distance.

Abstract

The study aimed to examine the effect of number of axillary buds on different types of mulberry hybrid and their interaction on the survival rate and cutting growth. The research was conducted using Random Design of Factorial Group (RDFG). It consists of two treatment factors, i.e. four type of mulberry hybrid (M. SHA 4 x M. LUN 109, M. multicaulis x M. indica, M. australis x M. indica, M. nigra x M. indica) and four different numbers of axillary buds with 3 replications and 30 replicates for each unit experiment. The research shows that there were effect of axillary bud number, types of mulberry hybrid, and their interaction on the survival rate and growth of stem cutting of mulberry hybrid. The number of axillary bud for the best growth of stem cutting of mulberry hibrid for the best sprout length of cutting and the highest survival percentage (81, 668%) was the 3 axillary buds, while the 4 buds was the best according to the rank of whole parameter. The best cutting type of mulberry hybrid according to the rank of whole parameter was M. australis x M. indica. Interaction beetwen mulberry hybrid and the best sprout number according to the rank of whole parameter was M. australis x M. indica with 4 sprout number.

Abstract

Hybridization Morus sp, has given a significant impact increasing leaf productivity. There ore some good performaning Morus hybrids such as M. nigra x M. indica (M.N1). M. australis x M. indica (M.AsI). and M. alba var kanva which might be good forfeeding materials of silkworm. However, it is necessariy to test the leafsuitability asfeeding material to the quality of cocoon that will be produced. For that purpose one set offeeding experimentation using Bombyx mori L, (bivoltine silkworm egg F1 China and Japan double crossed with the code C 301) and three kinds of mulberry was established. The researeh located in Grogolan village, with 500 m asl. altitude, 2.500 mm - 3.000 mm rain per year, 75% relative humidity and 25° .3,0°C temperature. The study was arranged Randomized Completely Design with three replications. The result showed that the effects of mulberry leaves were non signifcant for the survival percentage of silkvorm instar I-III, the survival percentage of silkworm instar IV-V, weight of cocoon, weight of cocoon shell, cocoon shell percentage, length of filament, weight of filament, filament percentage and reelability of cocoon, There were significant differences in rendement ofrearing. In general, leaves those three hybrids are suitable for silkwonn feeding.

Abstract

The aim of the experiment was to investigate to success rate of shoot cuttings on by different media and the height of hedging of Eucalyptus pellita F. Muell seedlings. The experiment was arranged in completely randomized design with two factors. The first factor was media compound, consists of 3 levels: sand, coconut husk and mixture of sand +coconut husk (1:1). The second factor was the height of hedging, consist of 4 levels : 5 cm, 10 cm, 15 cm, and 20 cm above the ground. The result showed that the effect the treatment was  significantly affected the success rate of the shoot cuttings. The cuttings from seedlings, which hedged at 15 cm above ground showed the best result. The media that gave the best rooting success was sand river. The average of rooting percentage was 15 - 95%, shoot length was 0,45 cm - 6,29 cm, shoot dry weight was 0,005 g - 0,049 g and volume of root was 0,020 ml - 0,123 ml.
