Drought Stress Decreases Morphophysiological Characteristics of (L.) Pierre a Biodiesel Tree.

<b>Background and Objective:</b> Drought stress is a condition of water shortage in plants. One tree species targeted for planting on marginal lands is <i>Pongamia pinnata</i> which produces oil for biodiesel feedstock. The aims of the present study were to evaluate the morphophysiological response of <i>Pongamia pinnata</i> and its resistance mechanism under drought stress at the seedling stage.

Beneficial Root-Associated Microbiome during Drought and Flooding Stress in Plants.

Crop productivity is seriously threatened by the rise in the frequency and severity of drought and flood events around the world. Reduced drought and flooding stress in vulnerable species and ecosystems depends on our ability to comprehend how drought and flooding affect plant physiology and plant-associated microbes. Involvement of both abscisic acid ABA-dependent and ABA-independent pathways has been noted during drought.

Physiological Responses to Drought in Six Rice (L.) Cultivars Cultivated in North Sulawesi, Indonesia.

Background And Objective: The drought-tolerant crop plants, including rice, are required for fulfilling food requirements when drought occurs in Indonesia. The response to drought stress in rice cultivars could be studied based on the morphological, anatomical and physiological characteristics. This study evaluated the drought tolerance based on the physiological characteristics at the vegetative phase in six rice cultivars cultivated in North Sulawesi, Indonesia.

Partial Submergence Tolerance in Rice ( L.) Cultivated in North Sulawesi at the Vegetative Phase.

Background And Objective: The partial-submergence-tolerant crop plants, including rice are required for fulfilling food needs when a flooding disaster occurs in Indonesia. The information of effective selection method for obtaining submergence tolerant rice is required for increasing the North Sulawesi capacity as a pillar of national food security. This study evaluated the partial-submergence-tolerance in 10 rice cultivars that are cultivated in North Sulawesi Province based on the morphological characters (plant height, shoot dry mass, shoot length, root dry mass, root length, root volume, shoot:root ratio and leaf number) at the vegetative phase.
