Analysis of the Factors Causing Differences in the Leaf-Senescence Pattern between Two Soybean Cultivars, Enrei and Tachinagaha: Comparison of root length and exudation rate among grafted plants [PDF]
To clarify the factors causing the differences in the leaf-senescence pattern between the soybean cultivars, Tachinagaha (T, late senescing cv) and Enrei (E, early senescing cv) , we grafted the T scion onto a T or E rootstock (T/T, T/E) andE scion onto ...

Differences in Sugar Accumulation and Mobilization between Sequential and Non-Sequential Senescence Wheat Cultivars under Natural and Drought Conditions. [PDF]
Wheat leaf non-sequential senescence at the late grain-filling stage involves the early senescence of younger flag leaves compared to that observed in older second leaves.

During winter, excised leaf tissue from Rumex obtusifolius degrades chlorophyll at twice the summer rate but the plant hormones, gibberellic acid and zeatin, inhibit the senescence rate by a constant percentage, regardless of season.

Intercropping and Nitrogen Fertilization Altered the Patterns of Leaf Senescence in Sorghum
Leaf senescence regulates grain yield. However, the modulation of leaf senescence in sorghum under legume-based intercrop systems and nitrogen (N) fertilization is not known.

Involvement of Abscisic Acid in PSII Photodamage and D1 Protein Turnover for Light-Induced Premature Senescence of Rice Flag Leaves. [PDF]
D1 protein in the PSII reaction center is the major target of photodamage, and it exhibits the highest turnover rate among all the thylakoid proteins.

Shade-Induced Leaf Senescence in Plants
Leaf senescence is a vital developmental process that involves the orderly breakdown of macromolecules to transfer nutrients from mature leaves to emerging and reproductive organs. This process is essential for a plant’s overall fitness.

359 Irrigation Rate and Nitrogen Concentration Affect Plant Growth and Leaf Senescence of Citrus Rootstock Seedlings [PDF]
The interactive effects of irrigation rate and nitrogen concentration of the irrigation water on the growth of seedlings of two citrus rootstocks were studied. Four-month old seedlings of Swingle citrumelo [ Citrus paradisi Macf.
