A raspberry leaf spot infection initially causes dark green circular spots on the upper side of young leaves, which will eventually turn tan or gray. [3] These spots are typically 1–2 millimetres (0.039–0.079 in) in diameter, but can get as big as 4–6 millimetres (0.16–0.24 in). [4]
Rubus probus, commonly known as Atherton raspberry or wild raspberry, is a scrambling shrub in the family Rosaceae native to Malesia and Queensland. [ 2 ] [ 3 ] Atherton raspberry is a rampant grower and, like most Rubus species, can form dense thorny thickets. [ 4 ]
Rubus deliciosus is a deciduous shrub or vine growing to 1.5 m (5 ft), rarely 3 m (10 ft), with arching stems. Unlike many species of Rubus, the flowering stems are perennial.
The raspberry is the edible fruit of several plant species in the genus Rubus of the rose family, most of which are in the subgenus Idaeobatus. [1] The name also applies to these plants themselves. Raspberries are perennial with woody stems. [2] World production of raspberries in 2022 was 947,852 tonnes, led by Russia with 22% of the total.
Rubus leucodermis is a deciduous shrub growing to 0.5–2.5 metres (1 + 1 ⁄ 2 –8 feet), with prickly shoots. [5] While the crown is perennial, the canes are biennial, growing vegetatively one year, flowering and fruiting the second, and then dying.
The raspberry spur blight fungus spreads through the pycniospores that are released from the pycnidia. The spores are released and infect other raspberry plants with the help of rain through open wounds or natural openings. [7] The fungus will then spread throughout the plant and will live in lesions during the winter to survive.
Rubus is a large and diverse genus of flowering plants in the rose family, Rosaceae, subfamily Rosoideae, commonly known as brambles. [3] [4] [5] Fruits of various species are known as raspberries, blackberries, dewberries, and bristleberries.
The yellow Himalayan raspberry is a threat to native flora because it can outcompete other plants. More specifically, it has higher photosynthetic rates, higher nitrogen fixation rates, and therefore a higher photosynthetic nitrogen use efficiency (or PNUE). [17] The yellow Himalayan raspberry is currently only invasive on Hawaii. [12]
