Taking two-year old Malus hupehensis as test material, this paper studied its root nitric oxide (NO) production under waterlogging, and the effects of exogenous NaNO3 on this production. Waterlogging for 3-9 days promoted the NO production significantly. Within the 12 days of waterlogging, the NO
To explore the effects of different nitrate nitrogen levels (N0, N1, N2, N3 and N4 were equivalent to 0, 2.5, 5, 10, 20 mmol·L-115NO3- -N, respectively) on the growth, photosynthetic characteristics and 15N absorption, utilization and distribution, Malus hupehensis seedlings were grown in cultural
Abscisic acid (ABA) biosynthesis has been widely characterized in plants, whereas the effects of ABA biosynthesis on nitric oxide (NO) generation in osmotic stress are less well understood. In this study, Malus hupehensis Rehd. 9-cis-epoxycarotenoid dioxygenase gene (MhNCED3) which is the key gene
In order to explore the effects of potassium fertilizer on the absorption and utilization of nitrogen fertilizer, and provide theoretical basis for scientific fertilization in apple orchard, Malus hupehensis seedlings were used to study the effects of different potassium levels (K0, K1, K2, K3, K4,
SnRK1 (sucrose non-fermenting-1-related protein kinase 1) plays an important role in plant carbon metabolism and development. To understand the mechanism of carbon and nitrogen metabolism regulated by MhSnRK1 from pingyitiancha (Malus hupehensis Rehd. var. pinyiensis Jiang), two transgenic lines
We compared two apple rootstocks -Malus prunifolia and Malus hupehensis - that differ in their tolerance to this abiotic stress. The former is considered drought-tolerant, the latter, sensitive. We monitored changes in their leaf ultrastructure and responses by their antioxidant defense systems.
