Sebagai organisme yang bersifat sessile, tumbuhan dapat merespon perubahan lingkungan, salah satunya adalah pencemaran udara. Pencemaran udara dihasilkan dari kendaraan bermotor berupa gas karbon monoksida (CO), sulfur dioksida (SO2), nitrogen oksida (NOx), dan volatile organic compounds (VOCs). Kontak polutan dengan daun menyebabkan akumulasi pada jaringan mesofil daun. Selanjutnya akan terjadi respon anatomi daun, antara lain peningkatan jumlah sel stomata, penurunan panjang lebar celah...
Pilea microphylla (L.) Liebm. adalah gulma yang diketahui mempunyai kandungan senyawa fenolik dan flavonoid cukup tinggi, sehingga sering dimanfaatkan sebagai tumbuhan obat.

Penelitian bertujuan untuk mengetahui organ batang, akar, daun dengan membandingkan ukuran sel akar serta muda dewasa. Sampel diambil secara acak, pembuatan preparat...
Abstract The siam ( Chromolaena odorata L.) and babandotan Ageratum conyzoides is weeds that often grow on cultivated land. Therefore it reduces crop productivity. Weeds are generally invasive because of an allelochemical compound can inhibit the growth existing plants around it. It potential to be used as a bioherbicide control weeds. This study aims examine effects different organs (leaf, stem, root) L. at concentrations photosynthetic pigments number stomata leaves Completely Randomized...
Mustard plants are a type of vegetable favored by most people. Demand formustard continues to increase along with the increasing population and awareness nutritional needs, but there obstacles in production. This is due lack nutrients needed mustard plant for its growth. One effort production adding through fertilization. Fertilizers divided into two types, namely organic inorganic fertilizers. However, long-term use fertilizers can reduce soil quality environmental health. alternative...
Waterlogging is a shallow flooding in the area of root and some parts shoot. It one most common types agricultural areas. The duration waterlogging affects plant growth yield response to stress by interacting with their ability adapt. Plant adaptability during resilience post-waterlogging recovery conditions. In this research, we examined tolerance Capsicum frutescens short (1 day), medium (3 days) long (10 waterlogging, as well its implications on post-waterlogging, recovery, reproductive...
One ofthe way able to be conducted improve productivity of soy is with treatment organic fertilizer at different time and dose. This research aim know influence liquid fertilization crop productivity, knowing dose giving best result also interaction between Research Complete Random Device factorial pattern . First factor that : D0 ( without manure), D1 0,7 ml / 1 water litre), D2 1,4 litre) D3 2,1 litre). Second T1 morning), T2 daytime) T3 afternoon). Parameter perceived by hat amounts pod...
Soybean [Glycine max (L.) Merr. cv Grobogan] is one of the most important commodities in Indonesia, but its production often decreasing due to weed disturbance. One type that has an allelopathic effect A. conyzoides. Allelopathy a phenomenon plant releasing chemical exudate into environment can suppress growth other plants. This study aims determine total phenolic content conyzoides and examine allelochemical extract against soybean. The experiment was performed completely randomized design...
Sand is media plant which was ability fasten the water absorb of very low. Sea weed Gracilaria verrucosa pregnant gel able to water.
