Abstract

Strategi untuk memperbaiki sifat pertumbuhan tanaman budidaya adalah dengan melakukan penelusuran sifat tumbuh tanaman baik secara morfologi dan fisiologi. Penelitian ini bertujuan untuk membandingkan keragaan  pertumbuhan kultivar  kedelai asal subtropis yaitu Tambaguro dengan kedelai asal tropis yaitu Anjasmoro yang diberi cekaman kekeringan. Penelitian di lakukan di daerah tropis yaitu di Kelurahan Pasirwangi, Ujung Berung, Bandung menggunakan pot. Pertumbuhan tinggi tanaman kedelai kultivar Tambaguro berkisar 12 cm pada umur 2 MST (minggu setelah tanam) sampai 29 cm pada umur 6 MST, sedangkan tinggi tanaman kultivar Anjasmoro berkisar 10  cm pada 2 MST sampai 32 cm pada 6 MST. Tampilan konduktasi stomata untuk kedua kultivar menunjukkan penurunan seiring umur tanaman (2-6 MST) yaitu berkisar 1094 - 1042 mmol/m²•s untuk Tambaguro, dan 892-1319 mmol/m²•s untuk Anjasmoro. Kultivar Tambaguro memperlihatkan pertumbuhan tinggi tanaman lebih baik dari kultivar Anjasmoro pada awal tumbuh, namun tidak pada pertumbuhan umur lanjut, sedangkan Kultivar Anjasmoro memiliki keunggulan dalam pertumbuhan tinggi pada umur lanjut. Tampilan fisiologis berupa respons konduktansi stomata dan fluoresensi klorofil kultivar Tambaguro lebih baik dari Anjasmoro disemua umur pengamatan, sedangkan dalam kodisi cekaman kekeringan, tampilan fisiologis kedua kultivar  cenderung sama menunjukkan ada potensi keunggulan genetik yang perlu dipertimbangkan, terlebih kultivar Tambaguro ini merupakan jenis kedelai berbiji besar sehingga memiliki keungulan secara ekonomis.Kata Kunci:

Abstract

Hybrid seed is not always have good longetivity. Therefore, breeder should select longetivity character from parental lines to get hybrid with longetivity characeter. Longetivity character can be revealed by physical and physiological identification of seed. The aim of this research was to identify physical and physiological of 16 parental lines genotypes of sweetcorn after storage. The experimental design in this research used Randomized Complete Design. The treatment in this reserach used 16 Unpad sweet corn parental lines with two replications. The data were analyzed using the F test, Scott Knott 5%, and Duncan 5%. The results showed that there were significant differences in seed electrical conductivity, germination capacity, vigor index, normal seedling dry weight and 100 seeds weight , and seed growth simultaneously at 2 month storage, and normal seedling dry weight and 100 seeds weight at 4 month storage. The best genotypes after storage was 578 which was from P parent, according to the delta value of seed quality changed.

Abstract

The growth of wheat plants can be determined by measuring leaf area index and net assimilation rate. Both measurements require leaf area data. Measurement of leaf area of wheat in Indonesia requires a method that is not only accurate, but also easier and cheaper. One of them is the regression method. The purpose of this study was to determine an accurate regression equation model in predicting wheat leaf area. This research was conducted from March to June 2021 at the Experimental Station and Plant Production Technology Laboratory, Faculty of Agriculture, UNPAD, Jatinangor, Sumedang. The materials used in this study were various leaf area printing papers from wheat plants aged 14 days after planting (DAP), 28 DAP, and 42 DAP. The regression equation was assembled from the relationship between leaf area with leaf width and length, then compared with the actual leaf area that measured by scanning. The results showed that the linear, quadratic, cubic, and logarithmic regression equations had a coefficient of determination of more than 90% to predict leaf area, at the age of 14, 28, and 42 DAP, as well as all plant ages. Quadratic regression had a limit of data that can be entered, so it needed circumspection in using the formula. Cubic regression tended to have better accuracy in predicting leaf area at 14, 28, and 42 DAP, but the accuracy was the same as other regression equations at all plant ages.

Abstract

The variation of the seed size in each species and individuals might be from of difference species adaptation for  a difference environment. This difference may also arise from the constraints of limited formation of seed size. The use of adaptive ciltivars on the growth environment is very influential on the succes in the farm field. This research was aimed to find the adaptation of phase and size seed of two cultivars of soybeans in Jatinangor and Cikajang. This research was held in Jatinangor (Sumedang regency) and Cikajang (Garut regency) from April to July 2016. The design that used in this research was Randomized Block Design (RBD) and Duncan at 5% rate. Improved cultivars that tested in this research were placed at Grobogan and Anjasmoro which were repeated 5 times. The results of experiment showed that adaptation of size seed showed of 100 grains and large seeds. The low temperature condition can increase of variability of seed size. Heterogeneity of environment can not sustain the size of soybean seed. Genetic and environment factors influence significantly for weight of 100 grains and seed size Grobogan in Jatinangor. The weight of 100 grains Grobogan in Jatinangor and Cikajang haved a greater than Anjasmoro. Environmental factors influence yield of soybean, weight of 100 grains of cultivars in Cikajang haved a greater than Jatinangor caused by the seed size.

Abstract

Seed propagation of strawberry by in vitro culture is needed to obtain high quality seeds of strawberry in large quantities. In in vitro culture, a large number of shoots is expected can be produced at the multiplication stage. Cytokinins type of PGR can be added to culture media to produce a large number of shoot. The focus of this research was to compare the effect of BAP and Kinetin affected Sweet Charlie strawberry multiplication. The experiment was located at the Seed Technology Tissue Culture Laboratory, Faculty of Agriculture, Padjadjaran University. The experimental design was a Completely Randomized Design (CRD) with two treatments of different types of cytokinin, namely Benzyl Amino Purine (BAP) and Kinetin at 1 mg L-1 on Murashige and Skoog (MS) basic media, each treatment was repeated four times. This study showed that BAP had a better effect than Kinetin on the number of shoots, number of leaves, and wet weight of strawberry Sweet Charlie cultivar. The addition of BAP was recommended over Kinetin to obtain the highest number of shoots, the highest number of leaves, and the highest wet weight of culture on strawberry Sweet Charlie cultivar.
