Abstract

Jatropha curcas Linn., is one of the oil plant producers, which can be processed to be the substitute fuel for diesel. The purpose of this research is to gain information of accession crosses compatibility level from different selected Jatropha. The study was conducted using seven accessions of Indonesia Jatropha planting material, which has a high productivity expectations, the HS-49, SP-16, SP-38, SP-8, SM-33, SP-34, and SM-35. The seven accessions were selected mass. Jatropha accessions used as an elder in the course of this research came from Gardens Jatropha Plant Germplasm Collection located in Asembagus–Situbondo. The crossings between seven accessions are not entirely successfully producing fruit and seeds. The crossing between SP-38 X HS-49 produced the highest number of fruits and seeds and followed by the crossing between SM-35 X HS-49. Of all the 42 crossing combinations, there are 14 crossing combinations that do not produce fruit and seeds at all.

Abstract

Agave seeds have a relatively short lifespan, thus require appropriate storage methods to maintain their viability and germination capacity. This study aimed to identify the optimal combination of storage duration and seedling treatments to preserve seedling quality and growth performance of agave. The experiment was conducted in a factorial randomized complete design with three replications. Each experimental unit consisted of 10 plants. The first factor was storage duration (0, 21, and 35 days). The second factor was seedling treatments involving seeds with: (1) complete leaves and roots, (2) complete leaves and half roots, (3) top leaves and half roots, (4) complete leaves without roots, and (5) top leaves and no roots. The seedlings were stored in a greenhouse with average temperature 25.67 °C and relative humidity 82.92%. The observed parameters included weight loss, germination percentage, seedling height, number of leaves, leaf length and width, number and length of roots, and fresh weight after 45 days of planting. The results showed that storage duration and root or leaf trimming significantly affected seed viability and seedling growth. Storage for 21 days combined with full leaves and half roots produced the highest germination percentage, growth performance, and fresh weight. Agave seeds can be stored for up to 35 days while maintaining high viability, and different seed types stored for 35 days still exhibited 100% germination.
