Anggrek Phalaenopsis sp merupakan jenis anggrek endemik di hutan tropis Kalimantan yang mempunyai nilai eksotik yang tinggi. Indonesia adalah negara tropis yang mempunyai plasma nutfah anggrek sekitar 6000.Â Pengembangan anggrek ini di Indonesia masih secara tradisional sehingga belum mampu bersaing dengan negara lain Taiwan, Malaysia, Singgapur dan china.Â Perkembangan anggrek akan lebih pesat dengan kemajuan teknologi yaitu sistem bioreaktor sehingga mampu menghasilkan dalam sekala industri.Â Tujuan dari pada penelitan ini adalah ingin mengetahui peran TDZ dalam perkembangan induksi PLB. Pemberian TDZ 1 ppm meningkatkan berat basah PLB dan jumlah PLB sebesar masing-masing 34 g dan 40.Â Pada perlakuan kontrol (tanpa TDZ) akan membentuk sistem perakaran yaitu jumlah akar (5,5) dan panjang akar ( 16 cm).Sebaliknya, dengan pemberian TDZ justru tidak memunculkan system perakaran melainkan terjadi perkembangan PLB yang terjadi.

The study aimed to identify variations in morphological and molecular character of sugarcane mutants from the mutation of Ethyl Methane Sulphonate (EMS). It used 21 sugarcane mutants and two non-mutant PS865 plants as controls. The treatments with inundation were carried out on 1-17 mutants and non-mutants, while the treatments without inundation were carried out on 18-21 mutant plants and non-mutants. The tolerance characteristics base on the agronomic characters. The RAPD molecular character was observed to detect changes in genotypes and kinship relationships of the plants tested. The results showed that the characteristics of tolerance to the best inundation were found in mutants 1, mutants 3 and mutants 6 which were characterized by the root volume (cm3), fresh root weight (g), sucrose content and brix value (%). Mutant plants treated with inundation showed higher levels of sucrose and brix values. Whereas the control plants in fats, showed lower levels of sucrose and brix. Changes in sugarcane mutant genotypes from non-mutants based on RAPD markers ranged from 14.7 - 56.7 % which resulted in an average polymorphic band of 35.1 % from 37 DNA bands and produced four main groups based on dendrogram analysis.

Tomato has the characteristics natural to damage. Damage fruits are caused by destitute of fruit quality and sensory attributes. The loss of tomato production on harvest in developing countries reached 50% due to the long duration of tomato distribution. Servo varieties of tomatoes are in demand by farmers because of their genetic advantages, high productivity, and abundant fruit weights. The shortage of servo varieties of tomatoes is the short shelf life of fruit, which is seven days after harvest. Short shelf life is influenced by fruit thickness and fruit hardness. In improving the quality and shelf life of tomatoes, potassium (K) nutrition plays a role in photosynthetic translocation, strengthens the cell wall, and involved in the lignification process of sclerenchyma tissue. Tomatoes, as climacteric fruits have a high respiration rate influenced by ethylene. Ethylene production can be inhibited by calcium chloride (CaCl2) application by strengthening the cell wall mechanism, cross-link with pectin, and increase the cell wall regeneration can change the texture of the fruit become harder, and it reduces sensitivity to physiological damage. Based on the treatment of this research, the quality and shelf life of servo varieties of tomato is increased.
