Abstract

The Salinity Stress Effect on Seed Viability and Vigor of Two Varieties of Soybean. Poorseed germination and crop stand are major problems in saline areas. The purpose of this study was todetermine the effect of salinity stress degrees of two varieties of soybeans. This research was conductedin March to April 2011 at the Seed Technology Laboratory, Bogor Agricultural University. Randomizedcompleted design was used with two treatment factors and three replications. First factor was varieties,i.e. Burangrang and Tanggamus. Second factor was consentrations of NaCl, i.e. 0, 2, 4, 6, 8, 10 g l-1.The results showed that the higher consentration of NaCl, the lower germination rate and seedling vigorindex. The NaCl concentration critical point of salinity stress based on germination rate of Burangrangand Tanggamus variety was 6 g l-1.

Abstract

In order to obtain high-quality seedlings, the effects of temperature, relative humidity, and photosynthetic photon flux density (PPFD), the seed of Phyllanthus niruri L. (meniran) were investigated in different microclimate (temperature, relative humidity, PPFD) environments. The present study was conducted from February to May 2024 at the experimental greenhouse and screen house of the National Research and Innovation Agency, Banten, Indonesia. Microclimate parameters were observed thrice daily at 8 am, 12 pm, and 3 pm during the research. The two environments significantly differ in microclimate. The average temperatures, relative humidity, and PPFD of environment 1 are 35.30±5.04 oC, 60.95±17.40%, and 483.33±406.00 µmol m-2 S-1, while environment 2 are 33.07±4.84 oC, 70.47±16.63% and 356.4±339.55 µmol m-2 S-1. All treatments were repeated 18 times. After the 21-day treatment during the seedling stage, P. niruri seedlings were observed, including the germination rate, number of leaves, shoot length, and chlorophyll content index. Results showed that the germination rate, leaves, shoot length, and chlorophyll content index significantly differ between P. niruri seedlings in both environments. Phyllanthus niruri that grow in environment 1 have a higher germination rate than in environment 2, likewise, the number of leaves, shoot length, and chlorophyll content index. This initial research showed that P. niruri seedling grows better in an environment with temperature, relative humidity, and PPFD, respectively 35.30±5.04 oC, 60.95±17.40%, and 483.33±406.00 µmol m-2 S-1.
